Field of the Invention The present invention relates to a tone parameter editing system including a tone signal generating device and a tone parameter editing device, which mutually exchange tone parameters while monitoring abnormalities such as a power supply disconnection. .

[0002]

2. Description of the Related Art Conventionally, there has been known an electronic musical instrument which sets and edits various tone parameters such as tone color data and generates a tone according to the tone parameters. For example,
In the music synthesizer, the user can appropriately set and edit the timbre data for determining the timbre, and can generate a musical tone using the timbre data.

Normally, setting and editing of tone parameters such as tone data and tone generation processing using the tone data are performed separately. In addition, there is no particular need for a function for setting and editing musical tone parameters for playing an electronic musical instrument. Therefore, in order to make the electronic musical instrument main body compact, an electronic musical instrument main body and a musical tone parameter editing device are separately provided.

On the other hand, there is known a system in which a tone generator is connected to a personal computer, tone parameters such as tone data created and edited by the personal computer are sent to the tone generator, and a tone is generated in accordance with the tone parameters.

[0005]

However, in such a conventional system, a device for generating a musical tone and a device for editing a musical tone parameter are separately provided as independent devices. In some cases, inconsistencies occurred when the pieces were cut into pieces. For example, there has been a problem that the edited musical tone parameter data causes a discrepancy between the musical tone generating device and the musical tone parameter editing device.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, the present invention provides a system in which a tone parameter editing device for setting and editing a tone parameter and a tone signal generating device for generating a tone are provided separately. It is an object of the present invention to provide a musical tone parameter editing system capable of avoiding inconveniences such as inconsistency of editing data between devices even when an abnormality such as a power supply interruption occurs.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an outline of a start-up operation in a tone parameter editing system according to an embodiment of the present invention. This musical tone parameter editing system includes an electronic musical instrument and a timbre data editing device.

An outline of the operation of the present system will be described with reference to FIG. On the electronic musical instrument side, after power-on (101),
An activation report (102) is sent to the tone color data editing device. Similarly, in the tone data editing device, the power is turned on (111).
Thereafter, an activation report (112) is sent to the electronic musical instrument.

Next, the timbre data editing device requests the electronic musical instrument for timbre data to be edited (113). And
It enters a standby state until the tone data is received. The electronic musical instrument transmits the designated timbre data in response to the timbre data request from the timbre data editing device (103), and enters a general operation (104). The general operation (104) is a general operation of an electronic musical instrument, for example, an operation of detecting a pressed key of a keyboard and generating a musical tone in a selected tone.

When the timbre data editing device receives the timbre data (114), it enters a general operation (115). The general operation (115) is a general operation as a tone color data editing device, such as an operation of editing received tone color data.

In this system, the electronic musical instrument and the timbre data editing device transmit and receive timbre data while periodically checking whether or not they are normally connected to each other. The confirmation method is performed by parallel communication between the electronic musical instrument and the timbre data editing device. Note that serial communication may be used instead of parallel communication.

Specifically, two unused lines in the parallel communication cable are used. One is used to check whether the electronic musical instrument is normally connected from the viewpoint of the tone data editing apparatus, and the other is to check whether the tone data editing apparatus is normally connected to the electronic musical instrument. Used to do. Here, the disconnected state is
This includes the state where one power supply is not turned on.

For a signal line for checking whether or not the tone data editing device is normally connected as viewed from the electronic musical instrument, the tone color data editing device outputs a logical HI level (5 V) to the signal line. From the viewpoint of the electronic musical instrument, if the signal line is at the HI level, the tone color data editing device is normally connected. If the signal line is at the LO level (0 V), it means that the timbre data editing device is not connected or the power is not turned on.

When confirming the connection of the electronic musical instrument from the timbre data editing apparatus, the connection is confirmed in the same manner. An electronic musical instrument may be in a general operating state even if a tone data editing device is not connected, but a tone data editing device cannot receive tone data unless an electronic musical instrument is connected. You have to wait for the main unit to start.

Here, a problem arises when the power is turned off while either the electronic musical instrument or the timbre data editing device is operating. Since both the electronic musical instrument and the tone data editing device periodically check whether or not the other party is connected, the tone data editing device is immediately connected when the disconnection of the tone data editing device from the electronic musical instrument is confirmed. Then, the operation proceeds to the general operation (or the general operation is continued). Conversely, if it is confirmed from the tone data editing apparatus that the electronic musical instrument is not connected, the electronic musical instrument waits for a restart.

Furthermore, although the connection of the other party is checked at regular intervals, if the power is turned off and on (interruption of the power supply) during the check cycle, the restart of the other party may not be noticed. There is.

For example, if the power of the tone data editing device is interrupted, the tone data editing device requests the electronic musical instrument for the tone data immediately after the tone data editing device is started. . However, if the timbre data editing device is performing an editing operation, the timbre data on the buffer of the electronic musical instrument that has been edited and sent to the electronic musical instrument side will be reloaded into the editing device. The electronic musical instrument needs to know that the timbre data editing device has restarted.

Conversely, when the electronic musical instrument restarts,
Unless the timbre data editing device knows that the electronic musical instrument has been restarted, the sounding state of the electronic musical instrument and the timbre data status of the timbre data editing device are different, which is not preferable.

As described above, even if one of them is restarted, it is necessary to inform the other party that it has been restarted. Notifying the restart is a start-up report operation described later with reference to a flowchart. Here, a distinction is not made between the restart and the initial startup, but since there is no problem in the process of the initial startup being treated as a restart, there is no problem.

Next, the system of this embodiment will be described in detail.

Next, the operation of the system of this embodiment will be described. First, the operation of the electronic musical instrument 200 will be described.

FIG. 3 is a flowchart for explaining the operation procedure of electronic musical instrument 200. When the power of the electronic musical instrument 200 is turned on, first, INST ON in step S1.
“1” is set in FLG, and initialization is performed in step S2.

Next, a mode switching process is performed in step S3, and it is determined in step S4 whether the current mode is the edit mode. The mode switching process is a process of switching between a normal mode and an edit mode according to a user operation. The normal mode is a normal mode as an electronic musical instrument. That is, in the normal mode, the user can select a timbre using the timbre selection operator 206 and generate a musical tone by operating the performance operator 205. The edit mode is a mode for editing timbre data.

If the mode is not the edit mode in step S4, it means the normal mode.
X END FLG is set to “0”, and the process proceeds to step S8. In step S8, the operation of the user's tone color selection operator 206 is detected, and if the operation is performed, the tone color selection process is performed according to the operation. Specifically, the timbre data of the selected timbre is read out from the timbre data memory 203, and T
This is processing to be set in the BUF 204. After that, TBUF
The musical tone is generated with the tone set in 204.

Next, a tone generation process is performed in step S9.

If the current mode is the edit mode in step S4, an interface (I / F) check is performed in step S5. The I / F check will be described later with reference to FIG. After step S5, it is determined in step S6 whether the flag EDITON RCV is "1". When the flag EDIT ON RCV is “1”, it means that the tone color data editing device 300 is normally connected, and the process proceeds to step S11. If the flag EDIT ON RCV is not "1", the tone color data editing device 300 is in a disconnected state and cannot perform the tone color data editing process, so the process proceeds to step S8 to perform the normal mode process.

In step S11, it is determined whether or not there is a tone color data transmission request from tone color data editing device 300.
If there is a tone data transmission request, the flag IF BUSY FLG is set to "1" in step S12, and the process proceeds to step S12.
At 13, it is determined whether or not the flag EDIT ONRCV is "1". When the flag EDIT ON RCV is "1", it means that the timbre data editing device 300 is normally connected, so that the timbre data requested in step S14 is read from the timbre data memory 203 to read out the timbre data editing device. Send to 300. Then, in step S15, it is determined whether or not the transmission has been completed. If the transmission has not been completed, the process returns to step S13 to repeat the transmission process.

After the transmission of the timbre data is completed in step S15, the flag IF BUSY FL is set in step S16.
G is set to “0” and the flag TX END FLG is set to “1”
And Next, the timbre data requested in step S17 is set in the TBUF 204, and the process returns to step S3.

In step S13, the flag EDIT is turned ON.
When the RCV is not “1”, the tone color data editing device 30
Since 0 is a non-connection state, step S1
In step S1, the TX END FLG is set to "0".
After setting the flag IF BUSYFLG to "0" in step 9, an I / F abnormality alarm process is performed in step S20, and the process returns to step S3. The I / F abnormality alarm process is a process of issuing an alarm that informs the user that the tone color data editing device 300 is not connected.

In step S11, the tone color data editing device 30
If there is no timbre data transmission request from 0, step S
At 21, it is determined whether or not there is a request for receiving timbre data from the timbre data editing apparatus 300. If there is a tone data reception request, the flag TX END FLG is determined in step S22.
Is "1". Flag TX END FLG
Is "1", the transmission of the requested tone color data has already been completed, and the flag IF BUSY is determined in step S23.
FLG is set to “1”, and the flag EDI is set in step S24.
It is determined whether or not T ON RCV is “1”. If the flag EDIT ON RCV is “1”, it means that the tone color data editing device 300 has been normally connected.
Receives the tone data (edited) from the TBUF 204
Transfer to Then, it is determined in step S26 whether or not the reception has been completed. If the reception has not been completed yet, the process proceeds to step S26.
Returning to 24, the receiving process is repeated.

When the receiving process is completed in step S26,
In step S27, the flag IF BUSY FLG is set to "0", and the process returns to step S3.

At step S24, the flag EDIT is turned ON.
When the RCV is not “1”, the tone color data editing device 30
Since 0 is a non-connection state, step S1
Proceed to 9 to perform I / F abnormality alarm processing.

If there is no reception request in step S21, or if the flag TXEND FLG is not "1" in step S22, the process returns to step S3. If the flag TX END FLG is not “1”, it means that a reception request from the timbre data editing device 300 was issued before the transmission of the timbre data was completed.
Since it is considered that some abnormality has occurred, a tone data non-transmission alarm may be issued.

Next, referring to FIG. 4, step S in FIG.
The I / F check routine and timer interrupt processing routine of No. 5 will be described.

In the I / F check routine, first, in a step S31, it is determined whether or not the flag TX END FLG is "1". The flag TX END FLG is "1"
If so, in step S32 the flag EDIT ON RCV
Is "0". Flag EDIT ON
When the RCV is “0”, the timbre data editing device 300
Is in a disconnected state, so that step S
At 33, I / F abnormality alarm processing is performed, and the routine returns.

In step S31, the flag TX END F
When LG is not "1" and when the flag EDIT ON RCV is not "0" in step S32, the process returns as it is.

In the electronic musical instrument 200 of this embodiment, a timer interrupt process is performed at predetermined time intervals to check whether or not the tone data editing device 300 is normally connected. In the timer interrupt routine, first, in a step S34, it is determined whether or not the flag IF BUSY FLG is "1". When the flag IF BUSY FLG is “1”,
Since data is transmitted and received between the electronic musical instrument 200 and the timbre data editing device 300,
The process proceeds to step S32 to check the connection state. If the flag IF BUSY FLG is not "1", the routine directly returns.

Next, referring to the flowchart of FIG.
The operation of the timbre data editing device will be described.

When the power of the tone color data editing apparatus is turned on, "1" is set to EDITON FLG in step S51, and initialization processing is performed in step S52.

Next, at step S53, the flag INST is set.
It is determined whether or not ON RCV is “1”. Flag I
When the NST ON RCV is “1”, the electronic musical instrument 20
Since it is determined that the electronic musical instrument 200 is online, a display indicating that the electronic musical instrument 200 is online is performed in step S54, and the process proceeds to step S56. Step S
If the flag INST ON RCV is not "1" in 53, it means that the electronic musical instrument 200 is not connected. Therefore, a display indicating that the electronic musical instrument 200 is offline is performed in step S55, and the process proceeds to step S56.

In step S56, an operation event of the tone data editing operator 305 is detected. Then, in a step S57, it is determined whether or not there is a tone data transmission request event. If there is a tone data transmission request event, the process proceeds to step S58; otherwise, the process proceeds to step S67.

In step S58, the flag INST O
It is determined whether or not N RCV is “1”. Flag INST
If the ON RCV is "1", it means that the electronic musical instrument 200 is connected normally, and therefore, step S5
9, the timbre data transmission request command is transmitted to the DA in FIG.
The electronic musical instrument 200 is transmitted using TA LINE. Then, in step S60, the BUSY FLG is set to "1", the flag RX ENDFLG is set to "0", and the process proceeds to step S61.

At step S61, the flag INST O
It is determined whether or not N RCV is “1”. Flag IN
When the ST ON RCV is “1”, the electronic musical instrument 200
Is normally connected, the timbre data transmitted from the electronic musical instrument 200 is received in step S62, and it is determined in step S63 whether the reception process is completed. If the receiving process has not been completed, step S6
Returning to step 1, the receiving process is repeated. When the receiving process is completed, the BUSY FLG is set to “0” and the flag RX END FLG is set to “1” in step S64, and the process returns to step S53.

At step S58, the flag INST is turned on.
If the RCV is not “1”, it means that the electronic musical instrument 200 is in a non-connection state.
Abnormal alarm processing is performed, and BUSY is determined in step S66.
FLG is set to “0”, and the flag RX END FLG is set to “1”, and the process returns to step S53. Step S61
If the flag INST ON RCV is not "1", the process also proceeds to step S65.

If the event is not a tone data transmission request event in step S57, it is determined in step S67 whether there is a tone data editing event. If there is a tone data editing event, the flag RX END is set in step S68.
It is determined whether or not FLG is “1”. Flag RX END
If the FLG is "1", the reception of the tone color data to be edited has already been completed, so that the tone color data editing process corresponding to the event is performed in step S69.

Then, in step S70, the flag BUSY
FLG is set to “1”, and the flag INS is set in step S71.
It is determined whether or not T ON RCV is “1”. When the flag INST ON RCV is “1”, it means that the electronic musical instrument 200 is normally connected.
The tone data edited in step S72 is stored in the electronic musical instrument 200.
Is performed, and it is determined in step S73 whether the transmission process has been completed. If the transmission process has not been completed, the process returns to step S71 to repeat the transmission process. When the transmission process is completed, in step S74, the BUSY FL
G is set to “0”, and the process returns to step S53.

At step S71, the flag INST is turned on.
If the RCV is not “1”, it means that the electronic musical instrument 200 is in the non-connection state.
Performs I / F abnormality alarm processing.

If it is determined in step S67 that the event is not a tone color data editing event, the process directly returns to step S53. Also,
In step S68, the flag RX END FLG is set to “1”.
If not, the process returns to step S53. The fact that the flag RX ENDFLG is not “1” in step S68 means that the timbre data editing event has occurred even though the reception of the timbre data transmitted from the electronic musical instrument 200 has not been completed. Alternatively, an alarm indicating the effect may be issued.

Next, referring to the flowchart of FIG.
A timer interrupt routine of the timbre data editing device 300 will be described. In the timbre data editing device 300, the timer interrupt routine is executed at predetermined time intervals.

In the timer interrupt routine, first, in a step S41, it is determined whether or not the flag BUSY FLG is "1". If the flag BUSY FLG is “1”, step S
At 42, it is determined whether or not the flag INST ON RCV is "0". If the flag INST ON RCV is “0”,
Since the electronic musical instrument 200 is not connected,
In step S43, the I / F abnormality alarm process is performed, the flag BUSYFLG is set to "0", and the flag RX
END FLG is set to “0” and the process returns.

At step S41, the flag BUSY FLG
Is not "1", or if the flag INST ON RCV is not "0" in step S42, the routine returns.

In the above embodiment, the abnormality caused by the disconnection of the power supply is detected, but the invention may be applied to other abnormalities. Also, the example of editing the tone data has been described,
The present invention may be applied to the editing of other musical tone parameters or to the editing of performance data in an automatic performance device. Further, a personal computer may be used as the editing device. .
