DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a MIDI (Musical Instrument Digit) supplied from, for example, a sequencer or the like.
al Interface) information or MIDI generated in the device itself
The present invention relates to an electronic musical instrument control device that performs predetermined processing on information and supplies the processed information to a synthesizer (sound source).

[0002]

2. Description of the Related Art Conventionally, MID has been used as an international standard for music information.
I is defined. Therefore, in an electronic musical instrument or the like configured to be able to handle MIDI information,
It is possible to generate a musical tone by driving a sound source based on musical tone information generated in the own device, and of course, generate a musical tone by driving a sound source in the own device based on MIDI information supplied from the outside. Has become.

[0003] However, such electronic musical instruments differ depending on the class, but cannot be said to have a sufficient function of processing MIDI information, and cannot be said to have excellent operability of equipment. Therefore, there is a demand for an electronic musical instrument control device that is excellent in operability and enables a player to freely and abundantly create musical tones according to his / her sensibility.

[0004] Conventional electronic musical instruments configured to handle MIDI information have the following various problems. (1) Conventionally, in addition to functions that can be played by oneself,
A master keyboard that can control DI devices was developed,
It has been put to practical use. This master keyboard has a function of simultaneously outputting about four channels of program change signals stored in advance in order to change the timbre. However, if you want to control more channels or output a volume signal at the same time,
It is necessary to repeat the same operation a plurality of times, resulting in poor operability.

(2) There are the following problems with the technology for transmitting and processing MIDI signals of electronic musical instruments. Generally, a sequencer has a function of setting a MIDI output channel. There are many synthesizers and the like that can set a MIDI output channel and a MIDI input channel. However,
Conventionally, the output source or the receiving side of the MIDI signal only recognizes the MIDI channel and performs the channel switching process. Therefore, when many MIDI devices are controlled by one device, it is necessary to set each MIDI device, and the operation is complicated, resulting in poor operability.

(3) Conventionally, M input from an electronic musical instrument or the like
2. Description of the Related Art There is known an electronic musical instrument control device as a MIDI information dividing device for dividing and outputting IDI information according to predetermined conditions and controlling a plurality of sound sources. For example, the connection destination of the MIDI information is switched to the MIDI connector (16
A MIDI patch bay that can be selected in units of channels) and a synthesizer that can switch timbres depending on the range and velocity of the same sound source are commercially available. On the other hand, in order to generate a musical tone suitable for a sound source, or to generate a musical tone using a sound source that the player prefers, the player performs MID for each MIDI channel.
There is a demand to select an output destination of the I information.
However, as described above, in the configuration in which the output destination is selected for each connector or the timbre is switched within the same sound source, the M
It was not possible to switch the output destination (sound a different sound source) for each IDI channel.

(4) Conventionally, the MIDI shown in (3) above
Although an electronic musical instrument control device is known as an information dividing device, in some devices, a channel message that directly affects sound generation is output from a first output terminal, and other messages are output from a second output terminal. It has specifications that request that However, such a configuration in which the output destination is selected for each connector or the timbre is switched within the same sound source as described above cannot meet such a demand.

(5) Conventionally, the MIDI shown in the above (3)
Although an electronic musical instrument control device as an information dividing device is known, a player has to generate a musical tone suitable for a sound source.
Alternatively, there is a demand to select an output destination according to the level of a note number in order to generate a musical tone using a sound source that the player prefers. For example, a note with a low note number is used for the bass and sounds the first sound source,
A sound having a high note number is a case where the second sound source is desired to be sounded for a melody. However, as described above, the output destination can be selected for each connector,
In a configuration in which the timbres are switched within the same sound source, it has not been possible to respond to a request to select an output destination according to the level of a note number.

(6) Conventionally, the MIDI shown in (3) above
Although an electronic musical instrument control device is known as an information dividing device, an electronic musical instrument generally has a limited number of simultaneous sounds due to its configuration. Therefore, a single electronic musical instrument cannot simultaneously generate more than a predetermined number of sounds. On the other hand, for example, an acoustic piano is capable of simultaneous sound generation by the number of keys provided. As in the case of such a piano, an electronic musical instrument capable of simultaneously producing more sounds is desired in order to enable a variety of performances using more sounds. However, as described above, the configuration in which the output destination is selected for each connector or the timbre is switched within the same sound source cannot meet the above demand.

(7) Conventionally, the MIDI shown in (3) above
Although an electronic musical instrument control device as an information dividing device is known, a player has to generate a musical tone suitable for a sound source.
Alternatively, there is a demand to select an output destination in accordance with the velocity of a message having a note number in order to generate a musical tone using a sound source desired by a player. However, in the configuration in which the output destination is selected for each connector as described above, or the timbre is switched within the same sound source, the request for selecting the output destination in accordance with the velocity of the message having the note number cannot be met. .

(8) Conventionally, as a method of changing the volume, a method of changing the volume using volume information is known.
By the way, musical instruments generally have a characteristic that the timbre changes as well as the volume in accordance with the strength of the keystroke. Therefore, the method of changing the volume based on the volume information has a disadvantage that it is almost impossible to change the volume according to the change in the velocity of the input sound. Further, in the case of creating automatic performance data, there has been a demand for creating data with the same velocity.

(9) Conventionally, there has been known an electronic musical instrument control device having a display device for displaying a negative fader value. Such an electronic musical instrument control device generally has 16 (17) faders, and is used for processing input MIDI information with the faders and outputting the processed MIDI information. In such a device, 1
In order to display the fader values of the six channels collectively on a 16-digit liquid crystal display device (hereinafter referred to as “LCD”), each fader value (usually 0 to 127) is represented by one character (5 × 5). It is necessary to express in 7). For this purpose, for example, as shown in FIG. 50 (a) or (b), it is conceivable to omit the ones place and express the fader value with 0 to 12. However, in a mode in which the fader value is added to the velocity of the input MIDI information and output, the fader value needs to be negative (for example,
"-64 to 63"). If this is to be expressed as “−6 to 6” by omitting the ones digit in the same manner as above, for example, as shown in FIG. In this case, minus "-" must be expressed in one line. As a result, the visual difference between the positive number and the negative number becomes small, and the visibility deteriorates. This tendency becomes particularly strong when other numbers are displayed on the left and right. Further, since numbers are arranged in 16 digits, it is very difficult to distinguish between "12" and "-2", for example, as shown in FIG. In this case, there is no point in displaying the values of all the faders until the characters are packed into 16 digits.

(10) Conventionally, there has been known a device which outputs MIDI volume information using a slide-type volume (fader). In such a device, the correspondence between the actual volume and the position of the fader may change due to a mode change on the transmission side or an operation on the reception side. That is, 16
In a device that controls the volume of 16 channels with a book fader, if the volume of the other device changes without permission, the position and volume of the fader must be adjusted unless the fader corresponding to the shifted channel is moved. Cannot match. Then all faders must be moved to achieve a perfect match. Since it is not possible to judge whether or not it is out of sight just by looking at it, there is a possibility that it may not be known which fader (channel) has been moved. Also, when the fader is moved when it is out of alignment, the volume suddenly changes. Therefore, it is often desirable to make the volume coincide at the same time as much as possible. Furthermore, if you try to match the fader with the actual volume, the fader will move,
There was a problem when I wanted to keep the fader fixed (not moving).

(11) Conventionally, there is a MIDI volume controller (mixer) and a master keyboard capable of outputting MIDI volume information. However, M
IDI volume information can be output only in, for example, the mixer mode for changing the volume, and the volume cannot be changed in another mode. Therefore, when it is desired to change the volume in the predetermined mode, it is necessary to return to the mode in which the volume can be changed once, and there is a disadvantage that the operability is poor.

(12) Conventionally, in a device that assigns exclusive data to a slide volume (fader) and outputs the exclusive data by moving the fader, the exclusive data is fixed or selected from a predetermined repertoire. Had become the way. For this reason, it has been difficult for a user to prepare exclusive data of a device desired by the user or to obtain exclusive data of a new device.

(13) Generally, in an electronic musical instrument such as a synthesizer, parameters such as timbre are set.
It has data input means such as one or more faders. Some have a dedicated remote controller. However, conventionally, a parameter to be changed is called by a mode switch or the like, and then data is changed by a fader or the like. Therefore, there is a problem that operability is poor.

[0017]

(1) First invention First, prior to executing the setup function of the present invention, the SETUP EDIT switch of the mode select key 28 is pressed to enter the setup edit mode. And
The following parameters are set and are written to a plurality (64) of patches in the setup storage area of the data memory 7. 1) The values of the volume for 16 channels and the master volume (0 to 127), transmission or non-transmission. 2) Program change numbers for 16 channels. There may be none. 3) Fader on / off information. 4) Patch name.

An example of using the setup edit function will be described. First, in the setup edit mode, the screen shown in FIG. 50 (a) is displayed on the display 22. In this state, change the patch number (# 01) and the patch name (BCDDEFG), and operate the fader to set a predetermined value to each channel.
When the EDIT switch is operated, the screen changes to the set volume screen shown in FIG. Here, the volume of each channel is set. Next, the SETUP EDIT switch is operated to switch to the screen shown in FIG. 9C, and the timbre is selected by sending the program change number. Further, the name of the setup patch can be set instead of the screen shown in FIG.

After the above-mentioned patch generation is completed, when the batch number in which the above data is written is input, the patch is called, and at the same time, the volume and the program change number for 16 channels are output from the electronic musical instrument controller. . At this time, the movement of the fader can be ignored so that the setting does not change even if the fader is moved. The setup function of the present invention is realized as follows. That is, S of the mode select key 28
By pressing the ETUP switch, the electronic musical instrument control device enters a setup mode, and a display as shown in FIG. 64 is made on the display 22. In FIG. 64, 1) shows a patch number, 2) shows a patch name, 3) shows a volume value of a channel at a cursor position, and 4) shows an approximate value of a volume of each channel. The details of the setup process will be described with reference to the flowchart of FIG.

In this setup process, first, the presence or absence of a switch event is checked (step S2301).
If it is determined that a switch event has occurred, it is checked whether the current mode is the setup mode (step S2302). Here, if it is determined that the mode is the setup mode, it is checked whether or not the setup number (setup number) is designated (step S2303). If it is determined that the setup number has been designated, that is, if the setup number designation input has been made from the ten keys 26, it is checked whether or not the input data has been determined (step S2304).

When it is determined that the input data has been determined, the determined data is transferred to the current program buffer C.
_P_B, the data load pointer is changed based on the value, and the setup data in the setup storage area indicated by the data load pointer is transferred to the setup data load area (step S230).
5).

Next, the preset volume buffer P
_V_B data (volume value) is loaded into the fader data buffer F_D_B (step S230)
6). In the preset volume buffer P_V_B,
The position data of the faders 1 to 17 is stored, and is moved to a fader data buffer F_D_B which also stores the position data of the faders 1 to 17. Next, the value of each channel of the fader data buffer F_D_B is multiplied by the master volume value, and the result is loaded into the volume data buffer V_D_B (step S230).
7).

Next, the program send (PROGRAM SEN)
D) Call the processing routine (see FIG. 24) (step S2308). In this program send processing routine, a MIDI format program change message (for 16 channels) is created. That is, first,
The counter pointer is initialized to zero (step S24)
1). The content of this counter pointer is used as a channel number in the following processing.

Next, the preset program buffer P
The data of _P_B is read (step S242). Program change data is stored in the preset program buffer P_P_B. Next, it is checked whether or not the most significant bit MSB of the read data is “1” (step S243). Here, when it is determined that the most significant bit MSB is “0”, it means that the program change data should be transmitted, and the counter pointer value is set to the channel number (ch N
A program change message with the status set to O) and the contents of the preset program buffer P_P_B as a program number is created and written to the internal event buffer IB (step S244).

Next, the counter pointer is incremented (step S245), and it is checked whether or not the content of the counter pointer has become "16" (step S24).
6). If it is determined that the value is not "16", the process returns to step S242, and the counter pointer is set to "1".
The same process is repeated until “6” is reached.

When it is determined that the counter pointer has become "16" by the above repetitive execution, the program change message of the channel whose MSB of the program change data is "0" is sent to the internal event buffer IB.
Then, the process returns from the program send processing routine and returns to step S2309 of the setup processing routine.

Next, the fader on / off flag F_O
It is checked whether the MSB of F_F is “0” (step S2309). Here, the MSB of the fader on / off flag F_OF_F is a flag that instructs volume transmission prohibition at the time of setup readout, and specifies “1” to prohibit transmission. Therefore, MS of F_OF_F
When it is determined that B is "1", the process returns from the setup processing routine without performing any processing.

On the other hand, if it is determined that the MSB of F_OF_F is “0”, it means that transmission is permitted, and “1” is written to all bits of F_E_F (step S2310). F_E_F is a flag that stores whether a fader event has occurred. Therefore, in this case, it is assumed that all faders have an event.

Next, a volume fader (VOLUME FAD)
ER) Call a processing routine (FIG. 25) (step S2311). In the volume fader processing routine, a control change message (for 16 channels) for changing the volume value is created. That is, first,
The counter pointer is initialized to zero (Step S25)
1). The content of this counter pointer is used as a channel number in the following processing.

Next, F_E_F is shifted left (or right) by one bit (step S252). Then, it is checked whether the carry is "1" (step S25).
3). If the carry is not "1", it is determined that there is no fader event corresponding to the channel, and the flow branches to step S256. On the other hand, when it is determined that the carry is “1”, it is determined that a fader event corresponding to the channel has occurred, and a value is read from the volume data buffer V_D_B (step S254). At this time, the volume value calculated in step S2307 of the setup processing routine is stored in V_D_B.

Next, a status using a counter pointer value as a channel number, a constant, and a volume message (control message) using the contents of V_D_B as a volume value are created and written into the internal event buffer IB (step S255).

Next, the counter pointer is incremented (step S256), and it is checked whether or not the content of the counter pointer has become "16" (step S25).
7). If it is determined that the value is not “16”, the process returns to step S252, and the counter pointer is set to “1”.
The same process is repeated until “6” is reached. When it is determined that the counter pointer has become "16" by the above-described repetitive execution, volume messages of all channels are created in the internal event buffer IB, and thereafter, the process returns from the volume fader processing routine. Return from the setup process. Thereafter, the message created in the internal event buffer IB is sent to the outside by the internal MIDI event processing routine (FIG. 21), and the external device is set to the initial state.

Next, although not directly related to the present invention, the operation in the setup edit mode for creating a setup patch will be briefly described below.
First, by pressing the SETUP switch of the mode select key 28 and then inputting a desired patch number with the numeric keypad 26, a display as shown in FIG. 64 is made on the display 22 (in the figure, the patch number is displayed). "01" is input).

In FIG. 64, 1) is a patch number,
2) indicates the patch name, 3) indicates the volume value of the channel at the cursor position, and 4) indicates the approximate value of the volume of each channel. By pressing the SETUP EDIT switch from this state, a setup volume edit mode is entered, and a display as shown in FIG. 65 is made on the display 22.

In FIG. 65, 1) indicates, by “ON” or “OFF”, whether or not a volume value is transmitted when this setup patch is called, 2) a value at a cursor position, and 3) a value at each cursor position. It shows the approximate value of the volume of the channel. Details of the setup volume editing process (setup setting process 1) will be described with reference to the flowchart in FIG.

In this process, first, the presence or absence of a switch event is checked (step S281). When it is determined that a switch event has occurred, it is checked whether or not the volume value transmission prohibition setting mode at the time of setup reading is set. Is performed (step S282). This is performed by referring to the mode flag register M_F_R. Here, when it is determined that the mode is the volume value transmission prohibition setting mode at the time of setup reading, it is checked whether or not the shift key 25 has been pressed (step S283). It is checked whether the "-NO DELETE" key has been pressed (step S284).

If it is determined that the "-NO DELETE" key has been pressed, information indicating volume value transmission prohibition is written to the fader on / off flag F_OF_F (step S285). On the other hand, if it is determined that the “-NO DELETE” key has not been pressed, “+ YES INSER
It is checked whether the "T" key has been pressed (step S286).

If it is determined that the "+ YES INSERT" key has been pressed, information indicating permission of volume value transmission is written to the fader on / off flag F_OF_F (step S285). As described above, information indicating prohibition or permission of volume value transmission of the selected setup patch is set.

Next, by pressing the SETUP EDIT switch again from this state, a setup program change edit mode is entered.
The display as shown in FIG. 66 is performed.

In FIG. 66, 1) indicates a program change number of a channel at a cursor position, and 2) indicates transmission or non-transmission of program change information of each channel by "T" or "-". The details of the setup program change edit processing (setup setting processing 2) will be described with reference to the flowchart in FIG.

In this processing, first, the presence or absence of a switch event is checked (step S2901). When it is determined that a switch event has occurred, it is checked whether or not a setup program setting mode is set (step S290).
2902). This is the mode flag register M_F_R
Is performed by referring to. Here, if it is determined that the mode is the setup program setting mode, it is checked whether or not the ten key 26 is pressed (step S29).
03), when it is determined that the numeric key 26 has been pressed,
It is checked whether the input data (program number) has been determined (step S2904). If it is determined that the input data has not been determined, the input data is written to the write data buffer, and the routine returns. In this case, it waits for the next numeric key input.

On the other hand, when it is determined in step S2904 that the input data is determined, the determined data (program number) is written to the address indicated by the data write pointer (step S2906). As a result, the program change data is written to the preset program buffer P_P_B. Next, the address indicated by the data write pointer, that is,
The MSB of the data written in step S2906 is set to "0" (step S2910). This instructs transmission of the data. Then, the routine returns from this routine.

If it is determined in step S2903 that the key is not a numeric key, it is checked whether the "-NO DELETE" key has been pressed (step S2907).
If it is determined that the "-NO DELETE" key has been pressed, the MSB of the data at the address indicated by the data write pointer is set to "1" (step S290).
8). This instructs not to transmit the data. Then, the routine returns from this routine.

In step S2907, "-NO DELET
If it is determined that the key is not the "E" key, "+ YES INSERT"
It is checked whether a key has been pressed (step S290).
9). Here, when it is determined that the “+ YES INSERT” key has been pressed, the MSB of the data at the address indicated by the data write pointer is set to “0” and the data is transmitted, as described above. And then return from this routine. With the above, the program change number of the selected setup patch is input,
Also, transmission / non-transmission is set.

Next, when the SETUP EDIT switch is pressed again from this state, a channel convert edit mode is entered, and the display 22 displays as shown in FIG. In FIG. 67, 1) indicates the changed channel number of each channel. For example, one channel input is output as two channels. The details of the channel convert edit processing (setup setting processing 3) will be described with reference to the flowchart of FIG.

In this process, first, the presence or absence of a switch event is checked (step S301). When it is determined that there is a switch event, it is checked whether or not a channel conversion setting mode is set (step S30).
2). This is performed by referring to the mode flag register M_F_R. If it is determined that the mode is the channel conversion setting mode, it is checked whether or not the numeric keypad 26 has been pressed (step S303). If it is determined that the numeric keypad 26 has been pressed, the input data (program number ) Is checked to determine whether it has been determined (step S304). If it is determined that the input data has not been determined, the input data is written to the write data buffer, and the routine returns. In this case, it waits for the next numeric key input.

On the other hand, if it is determined in step S304 that the input data has been determined, the determined data (changed channel number) is written to the address indicated by the data write pointer (step S295). This allows
The changed channel number is written to CH_C_T. Then, the routine returns from this routine. As described above, when the channel conversion process is completed and the setup function is executed, data is output to the changed channel.

Next, when the SETUP EDIT switch is pressed again from this state, the fader on / off edit mode is entered, and the display shown in FIG. 68 is displayed on the display 22. In FIG. 68, 1) indicates “ON / OFF” as to whether the fader is valid or turned when the setup patch is called. Details of the fader on / off edit processing (setup setting processing 4) will be described with reference to the flowchart of FIG.

In this process, first, the presence / absence of a switch event is checked (step S311). When it is determined that a switch event has occurred, it is determined whether or not the set-up mode is a mode for setting fader valid / invalid. A check is made (step S312). This is performed by referring to the mode flag register M_F_R. Here, when it is determined that the mode is for setting the fader valid / invalid, it is checked whether the “-NO DELETE” key has been pressed (step S313). here,
If it is determined that the "-NO DELETE" key has been pressed, fader invalid information is written to the fader on / off flag (step S314). Then, the routine returns from this routine.

In the above step S313, "-NO DELETE"
If it is determined that the key is not a key, it is checked whether the "+ YES INSERT" key has been pressed (step S315).
Here, when it is determined that the “+ YES INSERT” key has been pressed, information on the validity of the fader is written into the fader on / off flag (step S314). Then, the routine returns from this routine. As described above, when the fader on / off edit processing is completed and the setup function is executed, the function of enabling or disabling the fader is activated.

In the above-described setup edit mode, when the WRITE key 24 is pressed, a setup data memory writing process for writing the data set as described above into the setup storage area of the RAM 7 is executed. That is, when the WRITE key 24 is pressed, a display as shown in FIG. 69 is performed. In FIG. 69, 1) is the name of the patch to be written, and 2) is the patch number of the writing destination. Details of the setup data memory writing process will be described with reference to the flowchart of FIG.

In this process, first, it is checked whether or not there is a switch event (step S331). When it is determined that there is a switch event, it is checked whether or not the mode is the setup setting mode (step S332). This is performed by referring to the mode flag register M_F_R. Here, when it is determined that the mode is the setup setting mode, it is checked whether the WRITE key 24 has been pressed (step S333). Where W
If it is determined that the RITE key 24 has been pressed, a change process to the setup write preparation mode is performed (step S334). This is because the mode flag register M_F_
This is a process of setting the corresponding bit of R.

Next, the current program buffer C_
The write destination address based on P_B is written to the data load pointer (step S335), and the process returns from this routine. Current program buffer C
_P_B is a buffer that stores the currently read setup number. From the contents of C_P_B, the storage address of the corresponding setup number in the setup storage area is calculated.

In this state, when the "+ YES INSERT" key or the "-NO DELETE" key is pressed, the writing or the stop of the writing is performed. Details of this processing will be described with reference to the flowchart in FIG.

In this processing, first, the presence or absence of a switch event is checked (step S3401). When it is determined that there is a switch event, it is checked whether or not a setup write preparation mode is set (step S33).
2). This is performed by referring to the mode flag register M_F_R.

If it is determined that the mode is the setup write preparation mode, it is checked whether the "+ YES INSERT" key has been pressed (step S3403). When the "+ YES INSERT" key is pressed, the display shown in FIG. 70 is displayed on the display 22 to call attention of the operator. Here, when it is determined that the "+ YES INSERT" key has been pressed, all the setup data in the setup data load area (temporary) is transferred from the address of the data load pointer to the upper level (step S).
3404). Then, the routine returns from this routine.
This completes the writing of the setup data into the memory.

On the other hand, in step S3403, "+ YES INS
If it is determined that the key is not "ERT" key, "-NO DELETE"
It is checked whether the key has been pressed (step S34).
05). If it is determined that the "-NO DELETE" key has been pressed, the mode is changed to the setup setting mode (step S3406), and the routine returns. This returns to the state before the WRITE key 24 was pressed.

In step S3405, "-NO DELET
If it is determined that the key is not the “E” key, it is checked whether the numeric keypad 26 has been pressed (step S340).
7). If it is determined that the numeric key 26 has been pressed, it is recognized that the patch number has been changed, the current program buffer C_P_B is changed to a value corresponding to the numeric key input (step S3408), and the current program buffer C_P_B is changed. The base write destination address is written to the data load pointer (step S340).
9) Then, return from this routine. Thus, the processing in the setup edit mode is completed.

(2) Second invention When MIDI data is received at the input terminal IN1, the CPU
5 is received. The processing of this reception interruption is shown in the MIDI reception interruption 0 processing routine of FIG.

That is, first, it is checked whether or not the received data is a real-time message (step S51).
This is determined by checking the status (first byte) of the received data. If it is determined that the message is not a real-time message, the data is stored in the receive buffer RB0 (step S52), and the process returns from this processing routine. On the other hand, if it is determined that the message is a real-time message, it is checked whether the real-time separate flag is on (step S).
53). Then, if the real-time separate flag is on, transmission processing to the output terminal OUT2 is performed (step S55), and thereafter, the processing returns from this processing routine.

If the real-time separation flag is not on, the transmission processing to the output terminal OUT1 (step S54) and the transmission processing to the output terminal OUT2 (step S55) are performed, and thereafter, the process returns from this processing routine. That is, in this routine, it is determined only whether or not the received message is a real-time message.
1. Perform transmission processing for OUT2 and end the processing. If the message is not a real-time message, the received message is stored in the receive buffer RB0, and the process ends.

Similarly, when MIDI data is received at the input terminal IN2, a reception interrupt to the CPU 5 is made. The processing of this reception interruption is shown in the MIDI reception interruption 1 processing routine of FIG. That is, first, it is checked whether or not the received data is a real-time message (step S61). This is determined by examining the status (first byte) of the received data. If it is determined that the message is not a real-time message, the data is stored in the receive buffer RB1 (step S62), and the process returns from this processing routine. On the other hand, if it is determined that the message is a real-time message, the process returns from this processing routine without performing any processing.

That is, in this routine, it is determined only whether or not the received message is a real-time message. If the received message is a real-time message, the process is terminated without doing anything. If it is not a real-time message, the received message is stored in the receive buffer RB1, and the process is terminated. As described above, MIDI data from the outside is stored in the receive buffers RB0 and RB1.

On the other hand, the timer 11 interrupts the CPU 5 at predetermined intervals independently of the above operation. When this interrupt occurs, the received data (RB0, RB0,
RB1) The processing routine is started.

That is, first, it is checked whether or not the receive buffer RB0 is empty (Step S71). If not, the reception data processing subroutine (FIG. 8) is called (Step S7).
2). Next, it is checked whether or not the receiving buffer RB1 is empty (Step S7).
3) If not empty, the reception data processing subroutine (FIG. 8) is called (step S74). As described above, the receiving buffers RB0 and RB1 are constantly monitored, and if there is data, the reception data processing is performed.

The received data is processed according to the illustrated flow by a received data processing subroutine shown in FIG. Here, only the portions related to the present invention will be described, and other portions will be described in the corresponding invention section.

That is, first, the receiving buffers RB0, R
The received data is read from B1 (step S8)
01). Next, it is checked whether or not the received data is a status byte, that is, whether or not the received data is a first byte (step S802). If it is determined that the received data is a status byte, it is checked whether the received data has an exclusive status (step S8).
03), if it is not the exclusive status, the flow branches to step S807. Then, it is checked whether the received data is a channel message or a common message. When it is determined that the message is a channel message, a channel conversion processing routine (FIG. 19) is called.

That is, the channel conversion processing routine is called when the status is other than the exclusive status and a channel message is issued. In the channel conversion process, first, it is checked whether the channel (Ch) data included in the status is the same as the data set in the system channel register B_C_R (step S191).

When it is determined that they are not the same,
The channel (Ch) data included in the status is F_C
It is checked whether the data is the same as the data set in _B (step S191). If it is determined that they are not the same, the channel (C
h) Replace the data with the data stored in the area corresponding to CH_C_T (step S193). Then, the process returns from this processing routine.

An example of the channel conversion is shown in Table 1 below. Table 1 Channel conversion example

As can be understood from the above processing, when the channel indicated by the received data is the same as the system channel of the electronic musical instrument control device, and the channel set as the channel control target (set to F_C_B) If they are the same, the channel conversion process is not performed.

When the above channel conversion processing is completed, the flow returns to step S809 of the reception data processing subroutine, and the converted reception data is stored in the status buffer (MB).
_RS). Then, the process returns from this processing routine. As described above, according to the present invention, the MID
Since the electronic musical instrument control device is interposed between the output source of the I information and the receiving side of the MIDI information, the channel conversion is performed during the transmission of the MIDI signal.
The output source of the IDI information is associated with each channel on the receiving side of the MIDI information so that environment setting and the like can be easily performed.

(3) Third invention The following describes the division method when using the MIDI information division function of the electronic musical instrument control device of the present invention, and the setting mode of the associated parameter (indicated by []). There is something. 1) Off 2) MIDI channel [Output destination (1,
(2, 1 + 2 is not output)] 3) Odd / even note number [ON / OFF for each channel
Off] 4) Large / small note number [boundary value, output destination of higher value (1, 2), on / off for each channel] 5) High / low velocity [boundary value, higher value output 6) Channel messages, exclusive messages / real-time messages, system common messages

In such a configuration, the input M
The type and value of the IDI information are determined, the MIDI information is divided based on the selected division information and the set parameters, and the divided MIDI information is output to the output terminals OUT1 and OUT2.

FIG. 51 is a diagram showing a first connection example of the electronic musical instrument control device. In the figure, 40 is a synthesizer (or an electronic piano or the like), 41 is an electronic musical instrument control device, 42 and 43 are sound sources, and 44 and 45 are speakers.
When the mode 1) is set in such a connection relationship, the sound sources 42 and 43 are sounded in the same manner. When the mode 3) is set and the switch of the set MIDI channel is turned on, the sound of the odd-numbered keys is output from the sound source 42, and the sound of the even-numbered keys is output from the sound source 42. 42.

When the mode 4) is set and the MIDI channel is switched on with the boundary value being C3 and higher than that as the sound source 43, the threshold value is lower than C3 (note No. = 00).
To 3BH) is output from the sound source 42, and the signal above C3 (note No. = 3C to 7FH) is output from the sound source 43. When mode 5) is set and the MIDI channel is switched on with the boundary value being 64 and the sound source 43 being higher than 64, the sound source 42 is output at velocities 0 to 63, and the sound source 43 is output at velocities 64 to 127. Output from

FIG. 52 is a diagram showing a second connection example of the electronic musical instrument control device. In FIG. 52, a sequencer (or a personal computer or the like) 46 is connected instead of the synthesizer (or the electronic piano or the like). In such a connection relation, the mode 2) is set, and the output of the channel corresponding to the sound source 42 is set to “1”.
Assuming that the outputs of the other channels are all “2”, the output destination “1” is sounded from the sound source 42, and the output destination “2” is sounded from the sound source 43.

It is also possible to output to the sound source 42 and the sound source 43 in units of channels, or not to output both. Further, if the sound source 43 contains music data and it is desired to synchronize the performance with the performance of a sequencer (or a personal computer) 46, a mode
By setting 6), the performance information of the sequencer (or personal computer or the like) 46 is output from the sound source 42, and the information such as the clock is output from the sound source 43.

Although the functions of the electronic musical instrument control device have been schematically described above, the present invention is a portion corresponding to the mode 2). Hereinafter, details of the present invention will be described.

(A) Setting of division method (setting of separate menu) In order to execute the channel separation function of the present invention, first, a division method is set. Once the splitting method is set,
The corresponding bit of the separate flag SP_F is set to “1”. SP_F is a 1-byte flag register. The correspondence between the division method and each bit of SP_F is as follows:

(C) MIDI signal processing The flow of processing of a MIDI signal will now be described with reference to FIGS.
This will be described with reference to FIGS. 14 and 21. MID
The MIDI message input to the I input terminal IN1 is
The processing is performed according to the MIDI reception interrupt 0 processing flow of FIG. Since the details of this processing have been described in the section of the second invention, the description is omitted here. MIDI input terminal IN2
The MIDI message input to the
Processing is performed according to the reception interrupt 1 processing flow. The details of this processing have also been described in the section of the second invention, and a description thereof will be omitted here.

The MIDI reception interrupts 0 and 1 process received data on a byte-by-byte basis. The received data stored in the receive buffers RB0, RB1 are processed by the received data processing interrupt routine of FIG. In this routine, RB
If the received data exists in 0 and 1, the reception data processing subroutine shown in FIG. 8 is called to terminate the processing. Since the details of the reception data processing subroutine have been described in the section of the second invention, the description is omitted here. The reception data processing interrupt routine and the reception data processing subroutine perform the processing for each byte.

The processing when the note-on message is stored in RB0 will be described below. The note-on message is composed of three bytes as described below. "90 _H, 40 _H, 7F _H" ... M1 1 byte is the status byte, the type of messages in the upper 4 bits and represents the number of the MIDI channel in the lower 4 bits (9 = note on, 0 = Channel , 0 represent the first channel). The second byte indicates a note number. The third byte indicates velocity.

The reception data processing subroutine reads the reception data from RB0 (step S801) and checks whether or not it is a status byte (step S8).
02). If it is determined that the status byte is the status byte, the process goes through steps S803 and S807 to step S80.
9 is executed. That is, the status is stored in the status buffer in the MB. If the received message M1 has been stored, “90 _H ” is stored. Thus, the process returns from this subroutine.

After the above operation, when the received data processing subroutine is called again, “40” is determined in step S801.
_H ”is read out, and the process goes through step S802 to step S8.
10 is executed. That is, “40 _H ” is stored in the data buffer (MB).

Next, the message of the MB is completed.
It is checked whether or not it is (step S811).
If so, return from this subroutine. In this example,
"90 _H , 40_H "Is stored only,
Since the process has not been completed, the process is terminated as it is, and the process returns.
After the above operation is completed, the reception data processing subroutine is executed again.
Is completed, "7F" is set in step S801._H Read out
Then, step S810 is executed after step S802.
It is. That is, “7F_H "Ranks as data buffer (MB)
Will be delivered.

Next, it is checked whether or not the message of the MB is completed (step S811).
Proceed to step S812. In this example, "90 _H, 40
_H , 7F _H ”, the message is completed, and the process proceeds to step S812. In step S812, it is checked whether the message is note-on. In this case, since “90 _H ” is the status of the note-on message, the mode determination processing in step S813 is performed. Here, if it is determined that the mode is the channel separate mode, steps S814, S815,
The process proceeds to step S817 without performing the process of S816.

Then, the contents of the MB are transferred to the PTB. In this case, the three bytes of "90 _H, 40 _H, 7F _H" is transferred. Next, it is checked whether or not the status byte is a program change (Cn _H ) (step S818). In this case, since the status is not a program change status, a separate flag determination process is performed (step S820). That is, SP_F is checked. In this case, since SP_F is "01 _H ", the channel separation processing routine (FIG. 14) is called (step S821).

Next, regarding the channel separation processing,
This will be described with reference to the flowchart of FIG. In the channel separation process, first, it is checked whether the message is a common message (step S141). In this case, since it is not a common message, the process proceeds to step S142, and it is checked whether or not the bit of O_P_R1 corresponding to the channel included in the message is “1”. In this example, as shown in Table 3,
Since the bit of O_P_R1 is “0”, TB0_O
Call the P subroutine. (Step S143).
As shown in FIG. 8, the TB0_OP subroutine performs a process of storing one message in the transmission buffer TB0. By the process of step S143, all data stored in the PTB is transferred to TB0.

Next, it is checked whether or not the O_P_R2 bit corresponding to the channel included in the message is “1”. In this example, as shown in Table 3, O_P_
Since the bit of R2 is "1", the routine returns from this routine without calling the TB1_OP subroutine, that is, without writing the data in the PTB to TB1.

With the above processing, the process returns from the channel separation processing routine, and the reception data processing subroutine also returns to end the channel separation processing.

The data written to TB0 and TB1 is
The MIDI output terminal OUT is output by MIDI transmission interrupt 0 (FIG. 9) and MIDI transmission interrupt 1 (FIG. 10), respectively.
1. Output from OUT2 to an external device. Where M
The IDI transmission interrupt processing 0 routine is started by an interrupt generated upon completion of transmission of one message, and checks whether or not data exists in TB0 (step S91). A process of outputting the data to the output terminal POUT1 via the I / O port 10) is performed (step S92).

The MIDI transmission interrupt processing 1 routine is started by an interrupt generated upon completion of one message transmission, and checks whether data is present in TB1 (step S1).
01), if it is determined that there is data, send port 1
A process of outputting the data to the output terminal OUT2 via the (I / O port 10) is performed (step S102).

As described above, according to the present invention,
By setting O_P_R1 and O_P_R2 arbitrarily, the output terminal 1, the output terminal 2, or the output terminals 1 and 2 can be controlled so as to be divided and output for each channel. A suitable environment and utilization method can be realized.

(4) Fourth Invention The present invention is a part corresponding to the mode 6) described in the section of the third invention. Hereinafter, details of the present invention will be described.
According to the present invention, when bit 4 of SP_R is “1”, of the input MIDI information, the channel message and the system message are output from the output terminal OUT1, and the other (system common message, real-time message, etc.) are output from the output terminal OUT2. Output from

(A) Setting of division method (setting of separate menu) In order to execute the real-time separation function of the present invention, first, a division method is set. Since the details have already been described in the section of the third invention, they are omitted here. 73rd
The figure is a display example of the display 22 when the real-time separation is set. Hereinafter, the processing of the real-time separation in the example shown in FIG. 73 will be described.

(B) Division condition setting In this division, division conditions are not set. That is,
When the fourth bit from the upper bit of SP_F is set (see Table 2), the channel message and the system message are automatically output from the output terminal OUT1, and otherwise (system common message, real-time message, etc.).
Is output from the output terminal OUT2.

(C) MIDI Signal Processing Hereinafter, the flow of processing of MIDI signals will be described with reference to FIGS. 5 to 10 and FIG. The MIDI message input to the MIDI input terminal IN1 is the MIDI message shown in FIG.
The processing is performed according to the IDI reception interrupt 0 processing flow. That is, in this processing routine, it is checked only whether the received message is a real-time message. When it is determined that the received message is a real-time message, it is checked whether bit 4 of SP_F is “1” or not. If not, the transmission process is performed for the output terminals OUT1 and OUT2, and the process ends.

On the other hand, if the bit 4 of SP_F is “1”, the transmission processing is performed only to the output terminal OUT2, and the processing is terminated. If the message is not a real-time message, the received message is stored in RB0, and the process is terminated.

The MI input to the MIDI input terminal IN2
The DI message is processed according to the MIDI reception interrupt 1 processing flow of FIG. That is, in this processing routine, it is checked only whether the received message is a real-time message, and if it is determined that the received message is a real-time message, the processing is terminated without any processing. on the other hand,
If it is determined that the message is not a real-time message, R
The received message is stored in B1, and the process ends.

In the MIDI reception interrupt 0, 1 processing, the reception data is processed for each byte. The reception data stored in RB0, RB1 is processed by the reception data processing interrupt routine of FIG. In this routine, if reception data exists in RB0, RB1, the reception data processing subroutine shown in FIG. 8 is called to terminate the processing. Since the details of the reception data processing subroutine have been described in the section of the second invention, the description is omitted here. The reception data processing interrupt routine and the reception data processing subroutine perform processing for each byte.

The processing when the note-on message or the system common message is stored in RB0 will be described below. The note-on message is one of the channel messages, and is composed of 3 bytes as indicated by M1 in the third aspect of the present invention.

The system common message is composed of 3 bytes as described below. “F2 _H , 40 _H , 00 _H ”... M2 The first byte indicates the function of the message, and the following two bytes are parameters relating to the function.

Receive data processing subroutine (FIG. 8)
Stores the status of the received data in the status buffer in the MB, as already described in the third invention. If the received message M1 has been stored, "90
_H "is stored, and then the process returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the second byte of the reception data, that is, "40", as described above in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
Since only up to " _90H , _40H " are stored, it is determined that the message is not completed, and the routine returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the third byte of the reception data, that is, "7F", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
"90 _H, 40 _H, 7F _H" so stored until it is determined that the message is complete, the process proceeds to step S812.

After step S812, the process proceeds to the determination of the separate flag (step S820) through the same steps as described in the third invention. That is, the separate flag SP_F is checked. In this case, SP_F is "10
_H ", the real-time separation processing routine (FIG. 18) is called (step S825).

Next, the real-time separation processing will be described with reference to the flowchart of FIG. In the real-time separation processing, first, it is checked whether or not the message is a system common message (step S181). In this case, it is not a system common message (it is a channel message)
Therefore, TB0_OP is called (step S18).
3). That is, all data (one message) stored in the PTB is written to the transmission buffer TB0. The data written to TB0 is output from MIDI output terminal OUT1 to an external device by MIDI transmission interrupt 0 (FIG. 9).

Next, the operation when the received data is the system common message M2 will be described. Also in this case, the real-time separation processing routine (FIG. 18) is called through the same steps as described above, but differs from the above in that TB1_OP is called in this routine. That is, by calling TB1_OP in step S182, all data (one message) stored in the PTB is written to the transmission buffer TB1. The data written in TB1 is output from MIDI output terminal OUT2 to an external device by MIDI transmission interrupt 1 (FIG. 10).

As described above, channel messages that directly affect sound generation can be output from the first output terminal, and other messages can be output from the second output terminal. it can. Further, by such a divided output, it is possible to provide an environment and a utilization method suitable for a player's request and a sound source.

(B) Division condition setting In this division, the division conditions are O_P_R4, SPL
_P_F and N_N_B. O_P_R4
Is a 2-byte register, each bit corresponding to a MIDI channel. If a predetermined bit of O_P_R4 is “1”, a message of the MIDI channel corresponding to that bit is output to the MIDI output terminals OUT1 and OUT1.
2 is output. If the predetermined bit of O_P_R4 is “1” and the message of the MIDI channel corresponding to the bit is note-on, note-off or channel key pressure, the note number is determined according to the division condition, and the message is determined. Output terminal O
Output from only UT2 or only OUT1.

N_N_B is a 1-byte register,
The note number threshold is written. The note number of the MIDI message is compared with the content of N_N_B, and the output terminal OUT1 or OUT2 is determined according to the comparison result and the content of SPL_P_F.

SPL_P_F is a 1-byte register, and only its LSB is used. That is, if the LSB is "1" and the note number of the MIDI message is equal to or greater than the threshold, the message is output to the output terminal OUT1.
Output from If the LSB is “0” and the note number of the MIDI message is equal to or greater than the threshold, the message is output from the output terminal OUT2.

FIG. 75 shows an example of division condition setting. In the example shown in FIG. 75, note numbers C2 and higher are output from the output terminal OUT1, and the other numbers are output from the output terminal OUT2. Also, "S"
Indicates that the note number separation function is applied to the corresponding channel, and indicates that the note number separation function is not applied to a blank channel. In the latter case, the output terminals OUT1 and OUT1
2 will output MIDI information.

O_P_R in the example shown in FIG. 75

This indicates that this note number separation is applied to 5, 6, 8, and 9. The contents of N_N_B are shown in Table 5, note number C2 (30 _H corresponds to C2)
Indicates that it is a branch point. SPL_P_
The contents of F are shown in Table 6, where the note number is N_N
If it is equal to or more than the content of _B, it indicates that the output is to be made from the output terminal POUT1.

(C) MIDI Signal Processing Hereinafter, the flow of MIDI signal processing will be described with reference to FIGS. 5 to 10 and FIG.

The MI input to the MIDI input terminal IN1
The DI message is processed according to the MIDI reception interrupt 0 processing flow shown in FIG. 5, and the MIDI message input to the MIDI input terminal IN2 is processed according to the MIDI reception interrupt 1 processing flow shown in FIG. Are stored in RB0 and RB1, respectively, as described above. Also, the received data stored in RB0,1 is
The processing by the reception data processing interrupt routine of FIG. 7 is also as described above.

The processing when a note-on message is stored in RB0 will be described below. As the note-on message, the message indicated by M1 in the section of the third invention is used as an example.

Receive data processing subroutine (FIG. 8)
Stores the status of the received data in the status buffer in the MB, as already described in the third invention. If the received message M1 has been stored, "90
_H "is stored, and then the process returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the second byte of the reception data, that is, "40", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
Since only up to " _90H , _40H " are stored, it is determined that the message is not completed, and the routine returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the third byte of the reception data, that is, “7F”, as described above in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
"90 _H, 40 _H, 7F _H" so stored until it is determined that the message is complete, the process proceeds to step S812.

After step S812, the process proceeds to the determination of the separate flag (step S820) through the same steps as described in the third invention. That is, the separate flag SP_F is checked. In this case, SP_F is "04
_H ", the note number separation processing routine (FIG. 16) is called (step S823).

Next, the note number separation processing will be described with reference to the flowchart of FIG.

In the note number separating process, first, it is checked whether or not the message is a message having a note number (note on, note off, polyphonic key pressure) (step S1).
60). In the case of illustration, since it is a note-on message and has a note number, O_P_R4 is checked (step S162). That is, the bit of O_P_R4 corresponding to the channel number of the message is “0”.
Check if it is. In this case, since the status byte of the data stored in the PTB is “90 _H ”, it is checked whether or not the bit 1 of O_P_R4 is “0” (see Table 4).

If it is determined that bit 1 of O_P_R4 is "0", it is checked whether the LSB of SPL_P_F is "0" (step S16).
3). In the case of the example, since it is “1”, step S167
Then, it is checked whether or not the note number is smaller than the content of N_N_B (step S167). And
TP if note number is smaller than N_N_B
0_OP is called (step S168), and if not, TP1_OP is called (step S16).
9). In the illustrated example, the content of N_N_B is “30 _H ” and the note number in the message M1 is “40 _H ”, so TB1_OP is called in step S169, and thereafter, the process returns from this processing routine.

In TB1_OP, all data (one message) stored in the PTB is written to the transmission buffer TB1. The data written to TB1 is transmitted to MIDI output terminal OUT2 by MIDI transmission interrupt 1 (FIG. 10).
Output to an external device.

It is to be noted that, in step S163, SPL_
When it is determined that the LSB of P_F is “0”, it is determined whether or not the note number is equal to or greater than the content of N_N_B (step S164), and the note number is N_N.
If the content is not less than the content of _B, TP0_OP is called (step S165), and if the note number is not more than the content of N_N_B, TP1_OP is called (step S166).

As described above, according to the present invention,
Since the output destination can be selected according to the level of the note number, it is possible to generate a sound source desired by the player or a musical tone suitable for the sound source. Further, by such a divided output, it is possible to provide an environment and a utilization method suitable for a player's request and a sound source.

(6) Sixth invention The present invention is a part corresponding to the mode 3) described in the section of the third invention. Hereinafter, details of the present invention will be described.
According to the present invention, when bit 1 of SP_R is “1”, the MIDI information is output to the output terminal OU in accordance with the odd / even note number included in the input MIDI information.
It is output from T1 or the output terminal OUT2.

(A) Setting of division method (setting of separate menu) In order to execute the odd / even separate function of the present invention, first, a division method is set. Since the details have already been described in the section of the third invention, they are omitted here. FIG. 76 is a display example of the display 22 when odd / even separation is set. Hereinafter, the seventh
In the example shown in FIG. 6, the process of odd / even separation will be described.

(B) Setting of division condition In this division, the division condition is written in O_P_R3. O_P_R3 is a 2-byte register, and each bit corresponds to a MIDI channel. O_P_R
If the predetermined one bit of No. 3 is “1”, the message of the MIDI channel corresponding to that bit is output from both the MIDI output terminals OUT1 and OUT2. If the predetermined bit of O_P_R3 is “0” and the message of the MIDI channel corresponding to the bit is note-on or note-off, the message depends on whether the note number is odd or even. It is output from the output terminal OUT2 or OUT1.

FIG. 77 shows an example of division condition setting. In the example shown in FIG. 77, “S” indicates that the odd / even separate function is applied to the channel, and that the odd / even separate function is not applied to the blank channel. . In the latter case, MIDI information is output from both the output terminals OUT1 and OUT2.

O_P_R in the example shown in FIG. 75
Table 3 shows the contents of channel No. 3 and channels 1, 2, 7,
8, 9, 10, and 16 indicate that this odd / even separate is applied.

(C) MIDI Signal Processing Hereinafter, the flow of MIDI signal processing will be described with reference to FIGS. 5 to 10 and 15. The MIDI message input to the MIDI input terminal IN1 is the MIDI message shown in FIG.
It is processed according to the IDI reception interrupt 0 processing flow, and the MID
The MIDI message input to the I input terminal IN2 is
As described above, processing is performed according to the MIDI reception interrupt 1 processing flow of FIG. 6, and received data is stored in RB0 and RB1, respectively. Also, as described above, the reception data stored in RB0, RB1 is processed by the reception data processing interrupt routine of FIG.

[0167] The processing when a note-on message is stored in RB0 will be described below. As the note-on message, the message indicated by M1 in the section of the third invention is used as an example. Receive data processing subroutine (Fig. 8)
Stores the status of the received data in the status buffer in the MB, as already described in the third invention. If the received message M1 has been stored, "90
_H "is stored, and then the process returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the second byte of the reception data, that is, “40”, as described above in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
Since only up to " _90H , _40H " are stored, it is determined that the message is not completed, and the routine returns from this subroutine.

When the received data processing subroutine is called again after the above operation, this is also the third byte of the received data, that is, "7F", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
"90 _H, 40 _H, 7F _H" so stored until it is determined that the message is complete, the process proceeds to step S812.

After step S812, the process proceeds to the determination of the separate flag (step S820) through the same steps as described in the third invention. That is, the separate flag SP_F is checked. In this case, SP_F is "02
_H , the odd / even separate processing routine (FIG. 15) is called (step S82).
3).

Next, the odd / even separation processing is performed.
This will be described with reference to the flowchart of FIG.
I do. In the odd / even separate processing,
The message is note-on (step S
151), whether polyphonic key pressure
(Step S152) is checked. In the case of illustration,
Check on O_P_R3
(Step S153). That is, the message
O_P_R3 bits corresponding to the channel numbers of
Check whether it is "0". In this case, store in PTB
The status byte of the data being written is "90 _H "
Therefore, whether bit 1 of O_P_R3 is “0”
(See Table 7).

If it is determined that bit 1 of O_P_R3 is "0", it is checked whether or not the note number in the message M1 is an odd number (Odd) (step S154). When it is determined that the number is odd, the TB0_OP routine is called (step S1).
55) If it is determined that the number is even, the TB1_OP routine is called (step S156). Thereafter, the process returns from this processing routine.

In the illustrated example, the note number in the message M1 is “40 _H ”, which is an even number.
The OP routine will be called. TB1_OP
Then, all data (one message) stored in the PTB is written to the transmission buffer TB1. The data written in TB1 is output from MIDI output terminal OUT2 to an external device by MIDI transmission interrupt 1 (FIG. 10).

As described above, according to the present invention,
Since the output destination can be selected according to the odd / even note number, it is possible to increase the number of polyphony, albeit in a pseudo manner, and the player can play an electronic musical instrument as if playing an acoustic piano, for example. can do. Further, by such a divided output, it is possible to provide an environment and a utilization method suitable for a player's request and a sound source.

(7) Seventh Invention The present invention is a part corresponding to the mode 5) described in the section of the third invention. Hereinafter, details of the present invention will be described.
According to the present invention, when the bit 3 of SP_R is “1”, the MIDI information is output from the output terminal OUT1 or the output terminal OUT2 according to the velocity included in the input MIDI information.

(A) Setting of Dividing Method (Setting of Separate Menu) In order to execute the velocity separating function of the present invention, first, a dividing method is set. Since the details have already been described in the section of the third invention, they are omitted here. 78th
The figure is a display example of the display 22 when the velocity separate is set. Hereinafter, the processing of the velocity separation in the example shown in FIG. 78 will be described.

(B) Division condition setting In this division, the division conditions are O_P_R5, SPL
_P_F and velocity buffer V_B. O_P_R5 is a 2-byte register, and each bit corresponds to a MIDI channel. If a predetermined bit of O_P_R5 is “1”, a MIDI channel message corresponding to that bit is output from both the MIDI output terminals OUT1 and OUT2. Also, O
If the predetermined bit of _P_R5 is “0” and the message of the MIDI channel corresponding to the bit is note-on or note-off, its velocity is determined according to the division condition, and the message is output only to the output terminal OUT2 or OUT1. Output only from

V_B is a 1-byte register in which a threshold value of velocity is stored. The content of this V_B is M
The output terminal PUT1 or OUT2 that outputs the MIDI message is determined based on the comparison result and the content of SPL_P_F, compared with the velocity in the IDI message.

SPL_P_F is a 1-byte register, and only its MSB is used. That is, when the MSB is "1" and the velocity of the MIDI message is equal to or higher than the threshold, the message is output to the output terminal OUT1.
And if it is less than the threshold, the message is output from the output terminal OUT2. When the MSB is "0", if the velocity of the MIDI message is equal to or greater than the threshold, the message is output from the output terminal OUT2. If the velocity is less than the threshold, the message is output to the output terminal OU.
Output from T1.

In the output note-on message, the assigner input order, note number, and MIDI channel information are stored in the assigner. The assigner memory is provided in the work memory 6.

When a note-off message is input, it is checked with reference to the assigner from which output terminal the note number and the note-on message corresponding to the note-off message have been output from the MIDI channel. The note-off message is output from the output terminal to which the ON message has been output. If there is no empty entry in the assigner when the note-on message is input, the note-on with the youngest assigner input order (oldest stored order) is deleted,
The corresponding note-off message is output.

FIG. 79 shows an example of division condition setting. In the example shown in FIG. 79, the velocity “0”
"65" and above indicate that the output is from the output terminal OUT1, and the others are from the output terminal OUT2. Also,
“S” indicates that the velocity separate function is applied to the channel, and that the velocity separate function is not applied to a blank channel. In the latter case, the output terminal OUT1 or OUT2
Will output the MIDI information.

In the example shown in FIG. 79, O_P_R
Table 5 shows the contents of channel 1, 2, 3,
5, 6, 8, and 9 indicate that this velocity separation is applied. The contents of V_B are shown in Table 9 and indicate that the velocity “065” (41 _H ) is a branch point. Table 10 shows the contents of SPL_P_F
Indicates that if the velocity in the message is equal to or greater than the content of V_B, the message is output from the output terminal POUT1.

Table 11 shows an example of the assigner. Table 11, the current number of assignments is 3F _H, the rest indicates that no vacant only one entry 40 _H.

(C) MIDI Signal Processing Hereinafter, the flow of processing of MIDI signals will be described with reference to FIGS. 5 to 10 and FIG. The MIDI message input to the MIDI input terminal IN1 is the MIDI message shown in FIG.
It is processed according to the IDI reception interrupt 0 processing flow, and the MID
The MIDI message input to the I input terminal IN2 is
As described above, processing is performed according to the MIDI reception interrupt 1 processing flow of FIG. 6, and received data is stored in RB0 and RB1, respectively. Also, as described above, the reception data stored in RB0, RB1 is processed by the reception data processing interrupt routine of FIG.

[0187] The processing when the note-on message is stored in RB0 will be described below. As the note-on message, the message indicated by M1 in the section of the third invention is used as an example. Receive data processing subroutine (Fig. 8)
Stores the status of the received data in the status buffer in the MB, as already described in the third invention. If the received message M1 has been stored, "90
_H "is stored, and then the process returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the second byte of the reception data, that is, "40", as described above in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
Since only up to " _90H , _40H " are stored, it is determined that the message is not completed, and the routine returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the third byte of the reception data, that is, "7F", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
"90 _H, 40 _H, 7F _H" so stored until it is determined that the message is complete, the process proceeds to step S812.

After step S812, the process proceeds to the determination of the separate flag (step S820) through the same steps as described in the third invention. That is, the separate flag SP_F is checked. In this case, SP_F is "08
Since it is " _H ", the velocity separation processing routine (FIG. 17) is called (step S824).

Next, the velocity separation processing will be described with reference to the flowchart of FIG. In the velocity separation processing, first, it is checked whether or not the message is a message having a note number (note on, note off) (step S1701).

Here, in the case of the example, since the message has a note number, the flow advances to step S1702 to check whether or not the message is note-on. If it is determined that the note-on operation is performed, O_P_R5 is checked (step S1703). That is, it is determined whether or not the bit of O_P_R5 corresponding to the channel number of the message is “1”. In this case, since the status byte of the data stored in the PTB is “90 _H ”, it is checked whether or not bit 1 of O_P_R5 is “1” (see Table 8). Where O_P_R5
Is determined to be "1", the flow branches to step S826 (FIG. 8), and a note-on message is output from both of the output terminals OUT1 and OUT2.

On the other hand, if it is determined that bit 1 of O_P_R5 is not “1”, it is checked whether the MSB of SPL_P_F is “0” (step S170).
4). In the case of the example, since it is “1”, step S170
The process branches to 6 to check whether the velocity in the message is smaller than the content of V_B. If the velocity in the message is smaller than the content of V_B, TP1_O
P is called (step S1709), and if not, TP0_OP is called (step S171).
0). In the illustrated example, the content of V_B is “65 = 41 _H ” and the velocity in the message M1 is “7F _H ”. Therefore, the flow branches to step S1710 to call TB0_OP, and then branches to step S1711.

In TB0_OP, all data (one message) stored in the PTB is written to the transmission buffer TB0. The data written to TB0 is output from MIDI output terminal OUT1 to an external device by MIDI transmission interrupt 0 (FIG. 9).

It should be noted that, in step S1704, the SPL
When it is determined that the MSB of _P_F is “0”,
It is checked whether the velocity in the message is lower than the contents of V_B (step S1705). If the velocity in the message is higher than the contents of V_B, TP0_O is used.
P is called (step S1708), otherwise TP1_OP is called (step S1707),
Thereafter, the flow branches to step S1711. Step S17
Steps 11 and after are processing of the assigner at the time of the note-on message. It is assumed that the assigner at this time is set as shown in Table 11.

In the process of the assigner, first, it is checked whether or not there is a free space in the assigner (step S171).
1). This means that the maximum input rank (MAX INPUT NO.) Is compared with the maximum assigner number (40 _{H in the} example shown in Table 11), and if the maximum input rank is equal to the maximum assigner number, it is determined that there is no room in the assigner. I do.

Here, when it is determined that there is a free space in the assigner, the maximum input order is incremented (step S1713), and then the free entry of the assigner is set to MI.
Write the DI channel number (MIDI CH.), Note number (NOTE NO.), And output port (OUT). Then, the maximum input rank is written in the input rank (INPUT NO.) (Step S1717), and thereafter, the process returns from this processing routine.

In the case of the exemplified message, the note number is “40 _H ”, and the MIDI channel is “9H”.
_H ”,“ 0 ”as the output port, and“ 40 ”as the input order.
_H ”is written and the process ends. Upon completion of the above processing, the assigner is updated as shown in Table 12.

Next, a case where the following message M3 is input in this state will be described. "95 _H, 60 _H,
7F _H ”... M3 Since the processing up to step S1711 in FIG. 17 is the same as above, the description is omitted. In step S1711, the maximum input rank (MAX INPUT NO.) Is compared with the maximum assigner number. In this case, since the maximum input rank is equal to the maximum assigner number, it is determined that there is no vacancy in the assigner, and the flow advances to step S1712. Then, all input ranks (INPUT NO.) In the assigner are decremented.

Then, as a result of the decrement, a note-off message corresponding to the note number stored in the entry whose input rank becomes zero is output from the output port (output terminal) stored in the same entry (step). S1714). In this case, the ASSIGN NO.
Since the input order of _H 'is zero, "91 _H, 30 _H,
00 _H "of the message is output from the output terminal OUT2. As a result, the sound of the oldest assignment is erased.

Table 12 Assigner MAX INPUT N0. = 40 _H

Next, in the same entry, the note number, MIDI channel number,
Each information of the output port is written. In this case,
"60 _H" as note number "5 _H" as the MIDI channel, "0" as the output port, and terminates the writing by processing the "40 _H" as the input order. By the above processing, the assigner is updated as shown in Table 13.

Table 13 Assigner MAX INPUT N0. = 40 _H

Next, a case where the following message M4 is input in this state will be described. "90 _H, 40 _H,
Since 00 _H "... M4 process up to the 17 view of step S1701 is the same as above, description thereof is omitted. In step S1701, it is determined whether the message to be processed in the PTB is a message having a note number (note on, note off). Since the message M4 has a note number, the process advances to step S1702 to check whether the message is note-on. Here, since the message M4 is note-off (the velocity value of the third byte is zero), the flow branches to step S1718. Then, it is determined whether or not note-on corresponding to the input note-off exists in the assigner. That is, it is determined whether or not the MIDI channel of the assigner has the same channel number as that of the input message.

In the case of the example, since the note number corresponding to the note-off of the message M4 is stored in the entry of "40 _H " of the ASSIGN NO., There is a note-on corresponding to the inputted note-off. Is determined.
Therefore, the output port recorded in the entry,
That is, the message M4 is output from the output terminal 1 (step S1719).

Next, assigner erasure is performed (step S1720). That is, a control code indicating that the entry is vacant is written in the entry of ASSIGN NO. “40 _H ”. Next, all input ranks larger than the erased input ranks of the assigner are decremented (step S1).
721), and further decrement the current maximum assigner input rank (step S1772). In this case, ASSIG
The input rank of N NO. “40 _H ” is “40 _H ”, and there is no assigner input rank larger than this, so that the assigner input rank in the assigner area does not change.

As described above, according to the present invention,
Since the output destination can be selected according to the velocity of a message having a note number, an electronic musical instrument as a MIDI information dividing device capable of generating a sound source desired by a player or a musical tone suitable for the sound source. A control device can be provided.

(8) Eighth Invention The present invention, in a nutshell, allows direct manipulation of the velocity of input note information. That is, in the electronic musical instrument control device as the velocity operation device, the input MIDI signal is processed and output by, for example, a slide type volume (fader).

In the present invention, there are a velocity absolute that replaces the velocity of the input note information with a fader value, and a velocity offset that adds the fader value to the velocity of the input note information and outputs it as a new velocity. . FIG. 54 is a diagram showing an example of a velocity absolute, and FIG.
It is a figure showing an example of a velocity offset.

In these figures, the vertical axis indicates velocity, and the horizontal axis indicates time. The broken line indicates the velocity of the input data, and the solid line indicates the velocity of the output data. In the velocity absolute shown in FIG. 54, the velocity of the inputted note information is replaced by the velocity value corresponding to the position of the fader at that time.

In the velocity offset shown in FIG. 55, the center of the fader is set to “0”, and “−64” to “+”
63 ". This value is added to the velocity value of the input note information. The result of this addition is "+1
If it exceeds 27, it is set to "+127". When the addition result is equal to or less than “0”, the addition result is set to “+1”.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, when executing the velocity operation of the present invention, "MAN" of the mode select key 28 is executed.
Press the "UAL" switch. Thereafter, the processing is performed according to the schematic flow of the mode change processing in FIG. In the mode change processing routine, first, the presence or absence of a switch event is checked (step S481). If it is determined that a switch event has occurred, it is checked whether the event is a mode select key (step S4).
82). If it is determined that the key is the mode select key, a mode change process is performed (step S48).
3) Then, M_F_R is changed (Step S48)
4). That is, in the case of the velocity offset mode, the bit corresponding to the velocity offset mode of M_F_R is set to “1”, and the remaining bits are set to “0”.
To clear.

On the other hand, in the case of the velocity absolute mode, the bit corresponding to the velocity absolute mode of M_F_R is set to “1”, and the remaining bits are cleared to “0”. Next, a process of changing the internally generated data read pointer and the data write pointer is performed (step S485). Note that this step may be skipped depending on the function to be executed, and is skipped even in this velocity offset or velocity absolute mode.

Next, a display change process is performed (step S486). That is, in the case of the velocity offset mode, the display shown in FIG. 80 is performed. In FIG. 80, 1) is a 16-digit number corresponding to 16 faders 32, and the value “−64 to 63” of the fader 32 is changed to “−6”.
６6 ”. 2) indicates a fader value "-64 to 63" at the cursor position.

In the case of the velocity absolute mode, the display shown in FIG. 81 is performed. In FIG. 81, 1) is a 16-digit number corresponding to the 16 faders 32, and the value “000 to 127” of the fader 32 is changed to “0”.
-12 ". 2) displays the fader value "000 to 127" at the cursor position.

According to the present invention, two sets of input terminals I
N1 and N2 and output terminals OUT1 and OUT2, MIDI information input from input terminals is merged, a message is processed for each channel by 16 faders 32, separated, and then output from an output terminal. Things. Since the separation has already been described, the description is omitted here.

In the velocity offset mode, the value of the fader is set to "-64 to 63", the value of the fader is added to the velocity of the input note-on message, and the result is output from the output terminal. In velocity absolute mode, set the fader value to "0 to 127"
Then, the velocity of the input note-on message is replaced with the value of the fader and output from the output terminal.

Hereinafter, the flow of processing of the MIDI signal will be described with reference to FIGS. 5 to 10 and FIG. MI
The MIDI message input to the DI input terminal IN1 is processed according to the MIDI reception interrupt 0 processing flow shown in FIG. 5, and the MIDI message input to the MIDI input terminal IN2 is processed.
The message is processed according to the MIDI reception interrupt 1 processing flow shown in FIG.
The information stored in B1 is as described above. Also, R
As described above, the reception data stored in B0, B1 is processed by the reception data processing interrupt routine of FIG.

[0219] The processing when a note-on message is stored in RB0 will be described below. As the note-on message, the message indicated by M1 in the section of the third invention is used as an example. Receive data processing subroutine (Fig. 8)
Stores the status of the received data in the status buffer in the MB, as already described in the third invention. If the received message M1 has been stored, "90
_H "is stored, and then the process returns from this subroutine.

After the above operation, when the reception data processing subroutine is called again, the second byte of the reception data, that is, "40", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
Since only up to " _90H , _40H " are stored, it is determined that the message is not completed, and the routine returns from this subroutine.

When the received data processing subroutine is called again after the above operation, this is also the third byte of the received data, that is, "7F", as already described in the third invention.
_H ”is stored in the data buffer in the MB. in this case,
"90 _H, 40 _H, 7F _H" so stored until it is determined that the message is complete, the process proceeds to step S812.

In step S812, it is checked whether the message is note-on. In this case, "90
_H "is the status of the note-on message,
A mode determination process in step S813 is performed. If it is determined that the mode is the velocity offset mode, a velocity offset (VELOCITY OFFSET) processing routine is called (step S814).

Hereinafter, the velocity offset processing will be described with reference to the flowchart of FIG. In the velocity offset processing, first, data corresponding to the channel of the note-on message is read from O_D_B (step S111). Here, the value “0 to 7F _H ” of each fader 32 is stored in O_D_B. Therefore, the fader value is read from the O_D_B area corresponding to the channel number included in the note-on message.

Next, “40 _H ” is subtracted from the read fader value, and this is added to the velocity of the note-on message (step S112). As a result, the value “0 to 127” of the fader 32 is changed to “−64 to 6”.
The value converted to "3" is added to the velocity of the note-on message.

Next, it is checked whether or not the velocity has become "0" or less as a result of the addition (step S11).
3) If it is determined that the value is not more than "0", "1" is substituted as velocity data of the note-on message (step S114).

On the other hand, as a result of the addition, the velocity is “0”.
If it is determined that the velocity data is greater than “80 _H ”, it is checked whether the velocity data is “80 _H ” or more (step S).
115). When it is "80 _H" or more is determined, "7F _H" is substituted as velocity data of note-on message (Step S116). In cases other than the above, the addition result is used as it is as the velocity value of the note-on message.

As a result of this processing, when the velocity of the note-on message is out of the range of “1 to 127”,
The limit value will be set to “1” or “127”. Here, the lower limit is set to "1" because if it is set to "0", it becomes a note-off message. When the above processing is completed, the routine returns from the velocity offset processing routine.

On the other hand, if mode determination processing is performed in step S813 and it is determined that the velocity is in the absolute velocity mode, the velocity absolute (VELOCITY
ABSOLUTE) processing routine is called (step S
815).

Hereinafter, the velocity absolute processing will be described with reference to the flowchart of FIG.
In velocity absolute processing, first, O_
Data corresponding to the channel of the note-on message is read from D_B (step S121). Where O_
In D_B, the values “0 to 7F _H ” of each fader 32 are stored. Therefore, the fader value is read from the O_D_B area corresponding to the channel number included in the note-on message.

Next, it is determined whether or not the content of O_D_B is "0" (step S122). If not, the O_D_B data is written in the velocity of the note-on message (step S123). On the other hand, O_D_
When it is determined that the content of B is "0", "1" is substituted as the velocity data of the note-on message (step S124). As a result, when the velocity of the note-on message is “0”, “1” is set. When the above processing is completed, the routine returns from the velocity absolute processing routine.

Then, the flow advances to step S817 in the reception data processing subroutine to move the contents of the MB to the PTB. In this case, three bytes of the note-on message whose velocity has been changed are transferred. Next, it is checked whether or not the status byte is a program change (Cn _H ) (step S818). In this case, since the status is not a program change status, a separate flag determination process is performed (step S820). That is, S
P_F is examined. In this case, SP_F is “00 _H ”
Therefore, the subroutine TB0_OP is called (step S826). This TB0_OP subroutine performs a process of storing one message in the transmission buffer TB0, and by this process, all data stored in the PTB is moved to TB0.

Next, the subroutine TB1_OP is called (step S827). The TB1_OP subroutine performs a process of storing one message in the transmission buffer TB1, and by this process, all data stored in the PTB is transferred to the TB1.

The data written to TB0 and TB1 is
As described above, MIDI transmission interrupt 0 (FIG. 9) and MIDI transmission interrupt 1 (FIG. 10) respectively
The signals are output from the DI output terminals OUT1 and OUT2 to an external device. The fader value set in O_D_B is obtained by the fader event processing routine shown in FIG. Here, only the part related to the present invention in the fader event processing routine will be described.

In the fader event process, first, it is checked whether a fader event has occurred (step S22).
01), when it is determined that there is a fader event, it is checked whether the event is for fader numbers 1 to 16 (step S2202).
If it is determined that the event is for the fader numbers 1 to 16, a mode determination process is performed (step S2203). Here, if it is determined that it is a velocity offset or a velocity absolute, the fader data is written into an area corresponding to the fader having the O_D_B event (step S22).
04). Next, the display of the value corresponding to the fader on the display 22 is changed (step S2205), and thereafter, the process returns from this processing routine.

Here, the cursor movement processing for moving the cursor will be described with reference to the cursor movement processing routine of FIG. The cursor moving process is performed by various processes, and will be described here as a representative.

In the cursor moving process, first, it is checked whether or not there is a switch event (step S321). When it is determined that there is an event, it is checked whether or not the event is a cursor key (step S322). ). If it is determined that the cursor key is selected, the cursor position is changed, and the position data is input to the cursor (step S323). Next, a write address is input to a data write pointer based on the data. Thereafter, the process returns from the cursor movement processing routine.
As described above, the data write pointer is updated.

As described above, according to this embodiment, not only the volume can be changed by adding a volume signal to the input MIDI signal, but also the velocity data can be directly manipulated. Can be realized, and a note-on message having the same velocity value as certain automatic performance data can be easily created.

According to this embodiment, in the case of absolute, the velocity of the input data can be smoothed. In the case of offset, it is possible to balance input data for each channel at the stage of velocity.

In the case of the velocity offset in the above embodiment, the position of the fader is made to correspond to "0 to 1" instead of "-64 to 63", and this is multiplied by the velocity value of the inputted note information. By doing so, it is necessary to perform a truncation or a truncation in which the value is set to "+127" when the value exceeds "+127" and the value is set to "+1" when the addition result is equal to or less than "0". There is no.

(9) Ninth Invention In the electronic musical instrument control apparatus according to the present invention, for example, in the above-described velocity offset mode or the key balance mode described later, it is necessary to display a negative number on the display 22.

For example, in step S486 of the schematic flow of the mode change processing in the velocity offset mode (FIG. 48), the display as shown in FIG. 80 is performed.
The meaning of the display is as described above. In this case, a negative number is displayed in reverse (white display). Here, the 80th
The meaning of the schematic display of 1) in the figure is as shown in Table 14 below.

Table 14

The mode change processing schematic flow (forty-eighth
In step S485 of the figure, the address of the user font to be written to the character generator RAM is set to the address where the inverted display data is stored. In step S486, the user font is written into the character generator (CG) RAM of the LCD, and the display is changed according to the mode change.

Next, the details of the display change processing will be described in the fifth.
This will be described with reference to the flowchart of the display change process in FIG. Here, the LCD character generator is
It is assumed that the configuration is as shown in Table 15 below.

Table 15

First, the data at the cursor position O_D_B is entered into the register R (step S531). here,
As the register R, any register of the CPU 5 is used. Next, the contents (0 to 127) of the register R are converted into "-64 to 63" to be converted into a two-digit number and code, and displayed at the position 2) in FIG. 80 (step S).
532).

Next, the content of the register R is divided by "10" and stored in the register R (step S533). Thus, “0 to 127” becomes “0 to 12”. Next, the content of the register R is compared with "5" (step S534). Here, if it is determined that the content of the register R is larger than “5”, “2A _H ” is added to the content of the register R in order to retrieve the number in the CGROM,
The data is stored in the register R (step S535). If it is smaller than "5", it becomes the address of the CGRAM as it is. By the above processing, the address of the character generator is obtained in the register R.

Next, data is extracted from the character generator using the address obtained in the register R,
It is displayed at the cursor position (step S536).

As described above, in this embodiment, as shown in FIG. 58 (a), in order to roughly display a negative number with one character, the inverted number stored in the CGRAM is used. ing. This makes it possible to display a negative number effectively in a limited space without having to worry about the display location of minus “−”.

FIG. 58 (b) shows an example in which positive numbers and negative numbers are mixed and displayed. As an example,
Since the visual difference between the negative number and the positive number becomes large, both can be identified at a glance, and the visibility can be improved. In addition, the boundaries between adjacent numbers are not obscure.

In the above description, the case where the display polarity of the negative number is inverted has been described, but it is needless to say that the positive number may be inverted. Further, as shown in FIG. 59, the magnitudes of the negative and positive numbers may be changed so that both can be easily identified. Although FIG. 59 shows a case where a negative number is displayed small, it is needless to say that a positive number may be displayed small.

Further, in order to display a negative number, as shown in FIG. 60 (a), the main body of the number may be displayed small, and a bar may be displayed using the top one line. good. Although FIG. 60 (a) shows a case where the bar is displayed using one line at the top as a representative, for example, the bar may be displayed using one line at the bottom. In this case, the positive number may be displayed in a large size as shown in FIG. 7B, or may be displayed in a small size as shown in FIG. It is needless to say that a positive number can be displayed with a bar, and a negative number can be displayed larger or smaller without a bar.

(10) Tenth invention An electronic musical instrument control apparatus according to the present invention is a device for outputting MIDI volume information by means of a slide-type volume (fader). It is related to the function to deal with the case where the volume and the position of the fader have changed.

This function is implemented immediately after the electronic musical instrument controller is turned on or immediately after the mode is shifted from a mode other than the manual mode to the manual mode.
MIDI volume information corresponding to the fader position before the power is turned on or before shifting to the manual mode is output.

First, when executing the send fader position function of the present invention, the mode select key 28
Press the MANUAL switch. Thereafter, the processing is performed according to the schematic flow of the mode change processing in FIG. In the mode change processing routine, the bit corresponding to the manual mode of M_F_R is set to “1” as described above,
Clear the remaining bits to "0".

Next, send fader position key 3
When 0 is pressed, processing is performed according to the switch event processing schematic flow shown in FIG. Since the send fader position key 30 has the same function in all modes (there is a difference whether or not the function works), steps S272 and S273 are irrelevant in this embodiment. In step S274, processing for the send fader position key 30 is performed.

Next, the send fader position key processing will be described with reference to the flowchart in FIG. In this process, first, the SFP execution register (S
FPR) is multiplied with M_F_R, and it is checked whether or not the result is zero (step S821). here,
The SFP execution register is held in the data memory 8 as fixed data, and each bit is "1" for a bit corresponding to a mode in which the send fader position key corresponding to the mode is valid, and "1" for an invalid bit. 0 ". In M_F_R, since only the bit corresponding to the current mode is “1”, if the result of ANDing these two registers is not zero, the send fader position key is valid. .

If it is determined that the result is not zero, all bits of F_E_F are set to “1” (step S822). This F_E_F is used in the next volume fader (VOLUME FADER) processing routine.

Next, the volume fader (VOLUME FAD)
ER) Processing routine is called (step S82)
3). As described in the first aspect of the present invention, this volume fader processing routine performs the following for the channel corresponding to the bit of F_E_F in which “1” is set.
The volume data stored in V_D_B is read, a MIDI volume message is generated, and a process of writing the generated volume message to IB is performed.

In the send fader position processing, since all bits of F_E_F are set to “1”, a message having a volume value corresponding to the current fader position is generated for all channels. . The message created in the IB in this way is sent to the internal MIDI event processing routine (FIG. 21).
Is output to an external device.

The internal MIDI event processing routine is called and activated by a main routine (FIG. 20).

In this internal MIDI event processing routine, first, it is checked whether or not data exists in the IB (step S2101). If it is determined that data exists, the data is read from the IB (step S21).
02). Then, it is checked whether the read data is a status byte (step S210).
3) If it is a status byte, it is stored in the PTB (step S2104). Subsequently, the status is "F0 _H"
, That is, whether it is system exclusive (step S2105). If “F0 _H ”, the exclusive message is read and written to the PTB (step S2106). Then, it is determined whether or not one message has been determined (step S2107).
Steps S2106 and S21 until the message is determined
07 is repeatedly executed.

On the other hand, it is determined that the data read in step S2103 is not status data, or
Step S2105 the status is determined to be not "F0 _H", written data is read bytes from the IB to PTB (step S2108). And 1
It is checked whether the message is determined (step S210)
9) Step S210 until one message is determined
8, S2109 is repeatedly executed.

When one message is determined in this way, a separate determination process is performed (step S211).
0). That is, referring to SP_F, the eighth aspect of the third invention
As described with reference to the drawing, the separation process is performed. That is, if the channel separation flag is set, the channel separation processing is performed (step S211).
1) If the odd / even flag is set, odd / even separate processing is performed (step S21)
12) If the note number flag is set, a note number separating process is performed (step S211).
3) If the velocity flag is set, the velocity separation processing is performed (step S2114), and if the real time flag is set, the real time separation processing is performed (step S2115). The details of each of the above processes have already been described in the third to seventh aspects of the present invention, and a description thereof will be omitted.

If none of the above flags are set, TB0_OP is called (step S211).
6), one message is stored in TB0, and then TB1_OP is called (step S211).
7), one message is stored in TB1. In addition, in each process of the above-mentioned steps S211 to 2115,
TB0_OP, TB1 inside each processing routine
_OP is called.

According to the above processing, when the send fader position key 30 is pressed, if the send fader position key 30 is valid in that mode, a MIDI volume message for all 16 channels is output to the output terminal OU.
It will be output from T1 or OUT2.

As described above, according to this embodiment, only by pressing the send fader position key,
At that time, the volume corresponding to the fader position is output. In such a configuration, the switch may be pressed once when it is deemed to be out of place. As a result, IN
It is possible to cancel the difference between the fader, the display value, and the actual value caused by changing the volume value using the C and DEC keys.

Also, the fader is moved at the destination where the mode has been changed, and the fader and display value when returning to the original mode,
The deviation of the actual value can be canceled. Further, it is possible to correct a difference between a fader immediately after connection to an external sound source, a display value, and an actual value.

When the external tone generator receives a program change, it outputs volume information. In the case where a program change is received, when a fader, a displayed value, and an actual value are deviated, it is used to correct it. Can be.

[0270] The volume can also be rapidly changed by pressing the switch at the same time during the music. This embodiment can be applied not only to the case of outputting the volume of 16 channels and the entire main volume, but also to the case of outputting the volume of a single channel, several channels, or only the main volume.

The present invention can be applied not only to a case where volume information is output to the outside, but also to a case where a sound source or the like is provided in the apparatus itself and its volume is changed. Further, the present invention can be applied to a case where not only volume information but also other MIDI signals (for example, panpot signals) or signals other than MIDI signals are controlled. In addition, the present invention can be applied to a case where not only a slide type volume but also a rotary type or other volume is used.

(11) Eleventh Invention The present invention relates to a MIDI device having a plurality of modes including a (mixer) mode for controlling the volume of a plurality of MIDI channels, and having a master volume effective in other modes. The present invention relates to an electronic musical instrument control device as a volume information holding device for holding volume information in a mode other than the above.

Hereinafter, an embodiment of the present invention will be described with reference to the flowchart of FIG. First, a description will be given of a volume changing process by a normal fader. If there is a switch event, it is first checked whether a fader event has occurred (step S220).
1). If it is determined that a fader event has occurred, it is checked whether the event is an event of fader numbers 1 to 16 (step S220).
2).

Here, when it is determined that the event is the event of the fader number 1 to 16, the mode is determined (step S2203). The mode for changing the volume (Volume Fader, Setup, Channel d)
Ata Fader) is processed as follows. For example, Volume Fader
In the er) mode, the display change subroutine is called (step S2218), and the display indicating the volume value on the display 22 is changed.

FIG. 83 shows a display example. In FIG. 83, 1) is the volume value of the cursor position (when the fader changes, the cursor moves to the position of the channel corresponding to the changed fader), and 2) is the volume value of each channel. The approximate values are shown.

Next, fader data is written in the F_D_B area corresponding to the changed fader (step S2219). Next, the above step S2219
And F_D_B fader number 1
Multiply by the data stored in the area corresponding to 7,
V_D_B corresponding to the changed fader
(Step S2220).

Next, "1" is written to the F_E_F bit corresponding to the changed fader (step S2).
221). Next, the volume fader (VOLUME
FADER) processing routine is called (step S2).
222) Then, the process returns from this processing routine.

Volume fader processing routine (25th
Fig.) Is F_E as described in the section of the first invention.
For a channel corresponding to a bit in which _F is set to “1”, a process of reading volume data stored in V_D_B to generate a MIDI volume message and writing it to IB is performed.

In the send fader position processing, since the bit of F_E_F corresponding to the changed fader is set to “1”, a message having a volume value corresponding to the current fader position for that channel is set. Is generated. The message created in the IB in this manner is, as described above, an internal MIDI event processing routine (FIG. 21).
Is output to an external device.

Next, a description will be given of a volume change process by a master volume directly related to the features of the present invention. That is, if it is determined in step S2202 that the fader having the event is the fader number 17, the value of the fader number 17 is written in the corresponding area of F_D_B (step S2224), and then the value of the fader number 17 is written. And the data written in the F_D_B areas corresponding to the fader numbers 1 to 16, and multiplying the result by the fader number 1
Write to the V_D_B areas corresponding to １６16 (step S2225).

By the processing in step S2225, the same state as when an event has occurred in all of the fader numbers 1 to 16 occurs. Therefore, all bits of F_E_F are set to “1” (step S2226), and the volume fader is set. A (VOLUME FADER) processing routine is called (step S2222), and thereafter, the processing returns from this processing routine.

As a result, for all channels, a message having a volume value corresponding to the current fader position is generated in the IB, and the message created in the IB is transmitted to the external MIDI event processing routine (FIG. 21). Output to the device.

As described above, since the volume information of each channel is stored in F_D_B, it is possible to refer to this in other modes. Therefore, when the master volume (fader number 17) is operated, regardless of the mode, the volume information of all 16 channels is changed in F_D_B according to the change of the master volume, and the fader is changed to all 16 channels. By simulating that an event has occurred, the volume can be changed while maintaining the volume balance even in a mode in which the volume is not changed.

That is, in this embodiment, the fader position in the volume mode is stored in the storage means, and the master volume valid in other modes is referred to to calculate the volume value from each position, and This is MI
DI output is performed. As a result, even in modes other than the volume mode, the master volume is effective while maintaining the volume balance.

(12) Twelfth Invention The present invention relates to an electronic musical instrument control device as an exclusive editing device capable of not only transmitting MIDI exclusive data but also creating the exclusive data.

More specifically, the exclusive editing apparatus has an exclusive mode for outputting exclusive data and an exclusive edit mode for creating exclusive data. In this exclusive edit mode, the exclusive select (EXCLUSIVEE
It is set by pressing the (DIT) key.

Exclusive data is stored in fader 16
One book is associated with each book, and a set of 16 patches is provided. There are a total of 16 patches. In the following description, one of exclusive data, with the exception status as "F0 _H" to "F7 _H", 16
It is within bytes. This is represented by a display 22 composed of a 16 × 2 LCD.

FIG. 61 shows an example of a screen in the exclusive edit mode. In the figure, 1) is an exclusive name, 2) is a cursor position, and 3) is exclusive data. FIG. 62 shows keys related to exclusive editing in the operation panel shown in FIG.

♯♯ is input by the HIFT key 25 and “7” of the numeric keypad 26, which represents an exclusive variable byte.

When the fader is moved in the exclusive mode, the value of the fader is input to this byte and output. @ Is such that only one can be input in one exclusive. Also, it cannot be entered at the beginning. The cursor is moved with the cursor key 31. If the exclusive data is more than 6 bytes, it cannot be represented on the screen. Therefore, when the cursor reaches the end, scrolling is performed.

When the INSERT key is pressed, 1-byte "00" is input at the position of the cursor. If the total length is 16 bytes, no more can be inserted. Pressing the DELETE key deletes the byte at the cursor. However, the byte following “F0 _H ” (head)
Cannot be deleted. This is to prevent data without a maker ID from being created. When the WRITE key is pressed, the edited contents are stored. At this time, if the destination to be written is changed, copying can be performed.

FIG. 63 is an example of an exclusive light screen. In the figure, 1) indicates the patch number, and 2) indicates the order of the patch. An input is made using the numeric keypad 26 at the position where the cursor is located. The cursor can be moved with the cursor key 31. From here, if the YES key is pressed, the SURE display is displayed (see FIG. 95). N
Press the O key to return to the original exclusive edit mode.

When the YES key is pressed again from the SURE display, the data is written and the mode returns to the exclusive mode. N
When the O key is pressed, the exclusive light mode (6th
Return to FIG. 3). Lights are exclusive banks 1 to
Only for patch 4 (for users). Others are presets.

When the exclusive edit key is pressed, for example, twice, an exclusive name (edit) is displayed.
Enter mode. Here, the name of each exclusive data can be edited. This is entered using the cursor keys and the + and-keys.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. a) Exclusive data editing

First, the mode is changed. That is, exclusive edit (EXCLUSIVE EDI)

At this time, the display on the display 22 changes as shown in FIG.

Next, from the state shown in FIG. 85, “+ YES INS”
When an "ERT key" (hereinafter referred to as "INC key") is pressed, INC
(Data insertion) processing is performed. That is, when the input of the INC key is confirmed, it is determined whether or not the maximum number of exclusive data has already been input.
The process of shifting the data up to the 15th byte after the address indicated by the data write pointer one byte at a time and inputting "00 _H " to that address is performed.

In this process, first, the presence / absence of a switch event is checked (step S421). When it is determined that an event has occurred, it is checked whether the INC key has been pressed (step S422). Here, when it is determined that the INC key is pressed, it is checked whether the data is the maximum (step S423). here,
If it is determined that the data exists at the maximum, that is, up to the 16th byte, the process returns from this processing routine. If it is determined that the data is not the maximum, the data up to the 15th byte after the current position of the cursor is shifted by one byte. And write “00 _H ” at the current position (step S 4).
24). Then, the process returns from this processing routine.
At this time, the display on the display 22 changes as shown in FIG.

Next, from the state shown in FIG. 85, "-NO
DELETE key "(hereinafter referred to as" DEC key ")
Is pressed, DEC (data deletion) processing is performed according to the flowchart shown in FIG.

In this process, first, the presence or absence of a switch event is checked (step S431). When it is determined that an event has occurred, it is checked whether or not the DEC key has been pressed (step S432). Here, if it is determined that the DEC key has been pressed, it is checked whether the cursor is at the first byte (step S433).
If it is determined that the cursor is located at the first byte, the process returns from this processing routine. If it is determined that the cursor is not located at the first byte, the data at the current position of the cursor is deleted. The data up to the first byte is shifted by one byte, and the data “FE _H ” is loaded from the dummy area into the 16th byte (step S424). Then, the process returns from this processing routine. Data "F
“E _H ” means the end of exclusive data, and M
No IDI output or display is performed.

The relationship between MIDI output data, internal data and display is shown below. MIDI output data: “F0 40 01 02 03 04 05 06 07 7F F7” Internal data (16 bytes) “40 01 02 03 04 05 06 07 FF FE FE FE FE FE FE FE FE
At this time, the display on the display 22 changes as shown in FIG. 89. When the cursor is further moved to scroll to the next screen, the screen changes as shown in FIG. In this figure, “##” and the internal data “FF”
_H ", indicating that a value (fader position) should be entered.

(B) Exclusive name edit First, the mode is changed. That is, when the exclusive edit (EXCLUSIVE EDIT) key is pressed in the exclusive edit mode, the mode is changed according to the flowchart shown in FIG. 48, and the mode is changed to the exclusive name edit mode.
That is, in steps S483 and S484, M_F_
The bit corresponding to the exclusive name edit mode of R is set to “1”, and the other bits are cleared to zero. Next, in step S485, an exclusive name buffer EX_N is added to the data write pointer.
Set the start address of B. Thereafter, the display is changed (step S486). FIG. 91 shows an example of the screen displayed here. In the figure, 1) is EX_NB 1
The data in the second byte, 2), is obtained by converting the data in the second byte of EX_NB into an ASCII code.

Next, the cursor movement will be described. When the cursor key 31 is pressed, a cursor moving process is performed according to the flowchart shown in FIG. That is, in step S323, the cursor position is changed, and the position data is input to the Cursor. In step S324, a write address is input to a data write pointer based on the data.

Next, data input will be described. That is, in the above state, if there is a key input, the exclusive name edit processing during the exclusive edit processing is performed according to the flowchart of FIG.

In the exclusive name edit processing, first, the presence or absence of a switch event is checked (step S441). When it is determined that an event has occurred, it is checked whether or not the mode is exclusive name edit (step S441). S442). Here, if it is determined that it is an exclusive name edit, it is checked whether any one of the INC key and the DEC key is pressed (step S443). Here, when it is determined that either the INC key or the DEC key has been pressed, it is determined whether or not the key is the INC key.
If it is determined that the key is the INC key, the value of the address indicated by the data write pointer is incremented by "+1" (step S44).
5) Then, return from this processing routine. At this time, the display on the display 22 changes as shown in FIG.

On the other hand, if it is determined that the key is not the INC key, that is, the key is the DEC key, the value of the address indicated by the data write pointer is set to "-1" (step S445), and thereafter, the process returns from this processing routine. At this time, the display on the display 22 changes as shown in FIG.

C) Setting of Write Address in Data Memory First, the mode is changed. That is, light (WRIT
E) When the key 24 is pressed, a mode change process is performed according to the flowchart shown in FIG. Details of the mode change processing in step S483 of FIG. 47 are shown in write processing 1 during the exclusive edit processing of FIG. That is, first, it is determined whether or not there is a switch event (step S451). When it is determined that there is an event, it is checked whether or not the mode is exclusive edit (step S452). If it is determined that there is a light (WRI
It is checked whether the (TE) key 24 has been pressed (step S453).

If it is determined that the write key 24 has been pressed, the current mode is changed to the exclusive write mode (step S454), and the routine returns from this routine. Then, step S in FIG.
At 484, the bit corresponding to the exclusive write mode of M_F_R is set to "1" and the other bits are cleared to zero. Next, the display is changed (step S486). An example of the screen displayed here is the ninth screen.
It is shown in FIG. In the figure, 1) indicates a bank number, and 2) indicates a fader number.

Next, designation of a write address will be described. In this state, if there is a key input, the write process 2 during the exclusive edit process is performed according to the flowchart shown in FIG.

In this processing, first, it is checked whether or not there is a switch event (step S461). When it is determined that there is an event, it is checked whether or not the mode is exclusive write (step S46).
2). If it is determined that the mode is the exclusive light mode, it is checked whether the INC key has been pressed (step S463). If it is determined that the INC key has been pressed, the mode is changed to the exclusive tight waiting mode (step S464), and thereafter, the process returns from this processing routine.

On the other hand, if it is determined in step S463 that the key is not the INC key, it is checked whether the key is the DEC key (step S465). If it is determined that the key is the DEC key, the mode is changed to the exclusive edit mode (step S466). As described above, in the exclusive write mode, the INC
The mode can be changed by pressing the DEC key.

If it is determined in step S465 that the key is not the DEC key, it is checked whether the numeric key has been pressed (step S467). When it is determined that the numeric key is pressed, the address indicated by the data load pointer, that is, the exclusive bank number E
The input data is written in the X_BANK_NO area (step S468). As a result, the bank number is changed.

In the above state, if there is an input of the cursor key, processing is performed according to FIG. 32, and the cursor can be moved to the position 2) in FIG. 94. In this state, if an input is performed using the numeric keypad, the data is input as a fader number, the value is written in F_E_F, and then the top address of the area in which the edited exclusive data is written is calculated from the two values of the bank number and the fader number. Is written to the data load pointer.

Next, data writing will be described. In the exclusive light standby mode described above, IN
When the C key is pressed, the processing is performed according to the flowchart of the write processing 3 of the exclusive edit processing shown in FIG.

In this process, first, it is checked whether or not there is a switch event (step S471). When it is determined that there is an event, it is checked whether or not the mode is the exclusive write standby mode (step S471). Step S472). Here, if it is determined that the exclusive light waiting mode is set, it is checked whether or not the INC key has been pressed (step S473). Where INC
When it is determined that the key is pressed, the contents of the exclusive load area are changed to exclusive banks 1 to 3.
The data is transferred to the address after the address indicated by the data load pointer in the four storage areas (step S474). Then, the process returns from this processing routine.

If it is determined in step S473 that the key is not the INC key, it is checked whether the key is the DEC key (step S475). If it is determined that the key is the DEC key, write processing 2, ie, exclusive write, is performed. The mode is changed to the mode (step S476), and thereafter, the process returns from this processing routine.

As described above, in this embodiment, a mode for exclusive editing is provided in addition to the exclusive operation mode, so that exclusive creation, change, copy, etc. can be performed easily. It is. According to such a configuration, exclusive data can be easily created by referring to the manual without relying on the library.

(13) Thirteenth Invention The present invention relates to a technique for improving operability for setting parameters such as a tone color of an electronic musical instrument. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

A) Mode Change First, the mode change will be described. When the manual (MANUAL) key of the mode select key 28 is depressed, the mode is changed according to the flowchart shown in FIG. 48, and the mode is changed to the exclusive fader mode. That is, in steps S483 and S484, "1" is set to the bit corresponding to the exclusive fader mode of M_F_R, and the other bits are cleared to zero. Next, in step S485, the start address of the exclusive data buffer EX_DB is set to the internally generated data read pointer.

Thereafter, the display is changed (step S48).
6). FIG. 96 shows an example of the screen displayed here. In the figure, 1) shows the approximate value of the fader, 2) shows the value of the fader corresponding to the cursor position, and 3) shows the contents of the exclusive name buffer EX_NB. FIG. 96 shows an example in which “7” is written in EX_BANK_NO and “5” is written in Cursor.

(B) Cursor Movement Next, cursor movement will be described. Cursor key 3
When 1 is pressed, cursor movement processing is performed according to the flowchart shown in FIG. That is, step S
At 323, the cursor position is changed, and the position data is input to the Cursor. In step S324, a write address is input to a data write pointer based on the data.

In FIG. 96, when the cursor key 31 (right side) is pressed once, the cursor moves to the position indicating the fader number 6. In this case, Cursor has "6"
Is written.

When the cursor is moved, the exclusive data reading process shown in FIG. 26 is subsequently performed. In this process, first, the presence or absence of a switch event is checked (step S2601). When it is determined that an event has occurred, it is checked whether the mode is an exclusive fader (step S260).
2). Here, if it is determined that the fader is an exclusive fader, it is checked whether or not the bank number is switched (step S2603). Here, whether or not the bank number is switched is determined based on whether or not a ten-key input has been made. Here, since it is a cursor movement event, it is determined that the bank number is not switched, and
The flow branches to step S2607. In step S2607, it is checked whether or not the event is a cursor movement (step S2606).

If it is determined that the cursor is moved, the flow branches to step S2605 to execute EX_BANK.
The data load pointer is changed based on the values of _NO and Cursor, and exclusive banks 1-4 or 5 are changed.
The exclusive data indicated by the data load pointer in the storage areas to 16 is transferred to the exclusive load area.

In this case, EX_BANK_NO is “7”.
, And Cursor is “6”, so that the exclusive NO. 6 is written to the exclusive load area. Next, a display change process is performed (step S2606).
At this time, the display on the display 22 changes as shown in FIG.

(C) Change of bank number On the other hand, in the exclusive fader mode,
If there is a numeric key input, it is determined in step S2603 that the bank number has been switched. Next, it is checked whether or not the input data is determined (step S260).
4). This is determined by whether two digits have been input. When it is determined that the input data has not been determined,
It returns from this processing routine and waits for data to be input again.

In this state, the numeric keypad is operated, and if it is determined in step S2604 that the input data has been determined, the flow advances to step S2605 to perform the same operation as described above.

In FIG. 97, when “0, 2” is input, “2” is written into EX_BANK_NO. When step S2605 is executed, EX_BA
Since NK_NO is “2” and Cursor is “6”, the contents of the load pointer are exclusive NO. 6 indicates the start address of the data, and exclusive NO. Write all of the data No. 6 to the exclusive load area. Thereafter, a display change process is performed (step S2606). At this time, the display on the display 22 changes as shown in FIG.

(D) Fader event processing In the exclusive fader mode, when the fader is operated, the processing is performed according to the flowchart of the fader event processing shown in FIG.

An example in which the fader of fader number 13 is operated in the state shown in FIG. 98 will be described below.

If it is determined in step S2201 that the event is a fader event, it is checked whether the event is a fader event of fader numbers 1 to 16 (step S2202). In this example, since the fader having the event is the fader number 13, the process proceeds to step S2203 to determine the mode. If it is determined that the mode is the exclusive fader mode, the process proceeds to step S2213 to perform a display change process. At this time, the display 22 changes as shown in FIG. That is, the value corresponding to the position after the operation of the fader number 13 is displayed at the positions 1) and 2), and the fader number is displayed at the position 3).

Next, exclusive data read processing is performed (step S2223). This processing is started from step S2609 of the exclusive data read processing routine (FIG. 26). That is, the cursor is moved to the position corresponding to the fader where the event occurred (step S2609), and it is checked whether the mode is the exclusive fader mode (step S2610). If it is determined that the mode is the exclusive fader mode, the process branches to step S2605, and the same processing as described above is performed. At this time, the display on the display 22 changes as shown in FIG.

Next, fader data is written in an area corresponding to the O_D_B fader (step S22).
14). That is, “80 = 50 _H ” is written in the O_D_B area corresponding to the fader number 13 with a value corresponding to the position of the fader number 13 after the operation of the fader.
Next, “1” is set to the bit corresponding to the fader number 13 of F_E_F (step S2215).
Then, the exclusive fader processing routine (fourth
9).

Next, the exclusive fader processing will be described with reference to the flowchart of FIG. In this process, first, “F0 _H ” is written into the IB (step S4901). This is an exclusive status byte. Next, pointer reset is performed (step S4902). That is, the head address of the exclusive data buffer EX_DB in the exclusive load area is written to the internally generated data read pointer. At this time, it is assumed that the following data is stored in EX_DB. `` 40 00 10 00 04 3F 04 FF FE FE FE FE FE FE FE FE
”(Hexadecimal)

Next, the contents of the exclusive data buffer are read out (step S4903). Then, it is checked whether the read data is “FE _H ” (step S4904). If it is determined that the read data is not “FE _H ”, it is checked whether it is “FF _H ” (step S49).
06). If it is determined that the data is not “FF _H ”, the data is written to the IB (step S4).
909), the internally generated data read pointer is incremented (Step S4910), and then Step S49
Return to 03. Then, the series of processes described above are repeatedly executed. As a result, "40 00 10 00 04 3"
F 04 ”are stored in the IB.

In the course of this repetitive execution, step S4
If it is determined that the read data is “FF _H ” in 906, the content of the area corresponding to the fader number 13 of O_D_B is read (step S4907).
In this case, " _50H " is read. Next, the data is written into the IB (step S490).
8). Thereafter, the flow branches to step S4910, and the same operation as described above is repeated.

If it is determined in step S4904 that the read data is "FE _H ",
Write 7 _H "to IB (step S4905), control returns from the exclusive fader routine.

With the above processing, the following data is written to the IB. "F0 40 00 10 00 04 3F 04 50 F7" (all in hexadecimal) When the above processing ends, the fader event processing routine (FIG. 22) also returns. The data written in the IB is output to an external device by the above-described internal MIDI event processing routine (FIG. 21).

The electronic musical instrument control device according to the present invention is used as follows. Connect this unit and the synthesizer with MIDI, and match both channels. It is assumed that exclusive data for this synthesizer has been written in this unit.

When an arbitrary fader of the unit is moved, the tone color of the synthesizer is converted according to the fader position for the parameter assigned to the fader. According to this embodiment, the operability is improved, such as saving the trouble of calling parameters when editing a synthesizer or the like, and making it possible to change a plurality of parameters at the same time.
