DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A. First embodiment
A-1. Constitution
First, FIG. 1 shows an appearance of a system to which a performance data editing method according to the first embodiment of the present invention is applied. As shown in the figure, this system includes a personal computer (hereinafter referred to as a PC) 10 and operator devices 11, 12 connected to a PC (finger information writing means, special processing means, notification means) 10. And an electronic piano (notification means) 13.
[0017]
The PC 10 is a general PC including a CPU, a ROM, a RAM, a hard disk device, a floppy disk drive, and the like. Then, the editing process is executed in accordance with a performance data editing program installed in advance on a hard disk or the like, and controls the operating device 11, 12 and the electronic piano 13, and information input from the operating device 11, 12 The finger information is written to the performance data read from the floppy disk or the like based on the above. Details of the performance data editing process by the PC 10 will be described later.
[0018]
The operation device 11 has six operation devices 11a to 11f that simulate a piano keyboard, detects which of these is pressed, and outputs information corresponding to the detected operation device to the PC 10. Here, out of the six operators 11a to 11f of the operator device 11, the numbers from 1 to 5 are added to the five operators from the left side of the drawing from the right. These numbers 1 to 5 are associated with the thumb, index finger, middle finger, ring finger, and little finger of the left hand, respectively. Accordingly, when the first operator of the operator device 11 is pressed, finger information indicating the thumb of the left hand is output to the PC 10, and when the third operator is pressed, the middle finger of the left hand is indicated to the PC 10. Finger information is output. In addition, the 0th operator provided on the rightmost side in the drawing is an operator used for determining input information. Further, an LED (Light Emitting Diode) 11L is provided corresponding to each of the six operators, and is driven to emit light in accordance with control from the PC 10 or operation of each operator.
[0019]
The operator device 12 also has six operators 12a to 12f and corresponding LEDs 12L in the same manner as the operator device 11, detects which of these is pressed, and corresponds to the detected operator. The information is output to the PC 10. Here, 0 is added to the leftmost operator in the figure, and is an operator used for determining input information and the like, similar to the operator device 11 described above. Numbers from 9 to 13 are added from the left to the five operators from the second operator from the left side of the figure. These numbers from 9 to 13 correspond to the thumb, index finger, middle finger, ring finger, and little finger of the right hand, respectively. Therefore, when the ninth operator of the operator device 12 is pressed, finger information indicating the thumb of the right hand is output to the PC 10, and when the operator of the eleventh is pressed, the middle finger of the right hand is displayed to the PC 10. Finger information is output. That is, the operator device 11 is an operator device for outputting finger information of the left hand to the PC 10, and the operator device 12 is an operator device for outputting finger information of the right hand to the PC 10. In this way, an operator device may be provided for each left hand and right hand, but finger information for both the left hand and the right hand may be input with one operator device. In this case, there are a method of providing a left / right selection button or the like, or a method of providing ten operators so as to correspond to left and right fingers.
[0020]
The electronic piano 13 is used as a device that electronically generates musical tones that are determined based on a control signal supplied from the PC 10 during performance data editing processing to be described later. Therefore, an electronic piano may be used as long as the device has an electronic musical sound generating function, but an electronic piano is used in the present embodiment.
[0021]
A-2. Performance data editing process
Next, the performance data editing process by the PC 10 using the system configured as described above will be described.
[0022]
A-2-1. Overview
First, an overview of performance data editing processing by the PC 10 will be described with reference to FIG. First, performance data recorded on a recording medium such as a floppy disk is read out to a RAM which is a working area (step S1). Here, the performance data is data including information indicating a musical note sequence constituting a musical piece, for example, MIDI data.
[0023]
Next, it is determined whether or not there is an area for writing finger information in the read performance data (step S2). Here, the finger information is information input from the above-described operation device 11 or 12, and a finger for playing a note to be edited (in the case of a piano, a finger to press a key) in an area in which the finger information is written. Enter the information shown. It is determined whether there is an area for inputting such finger information.
[0024]
If it is determined in step S2 that there is no area for writing finger information in the performance data, an area for writing finger information in the performance data is created (step S3). Here, FIG. 3 conceptually shows the creation process of the finger information writing area. As shown in the figure, after all the performance data for one musical piece has been read out to the RAM, the information (note information A, B, C, D...) Indicating each note is scanned from the performance data and scanned. A finger information writing area (finger information A, B, C, D...) Is created for each note information. Thereby, a finger information writing area can be created for each note constituting the music. Note that in MIDI data, each note is represented by a note-on event, a note-off event, and duration data indicating the time interval of each event, so finger information is basically added only to the note-on event.
[0025]
Thus, after the finger information writing area creation process is completed, or when there is a finger information writing area (including finger information already written) in advance in the performance data, the finger information is to be written at that time. Is notified to the editor (step S4). In the initial state, the first note of the musical composition data is notified to the editor. Here, as a method of notifying an editor of a target note, there is a method of causing the electronic piano 13 to generate a musical sound corresponding to the note as will be described later. Further, as shown in FIG. 4, a score constituting the music may be displayed on the display screen of the PC 10, and notes to be edited in the score may be indicated by arrows. In addition, when displaying a score on the screen, not only the method indicated by the arrow as shown in FIG. 4, but the target note can be displayed in a different color from other notes, or can be displayed in a blinking manner. You may make it do.
[0026]
Then, it is determined whether or not finger information is input from the operator devices 11 and 12 (step S5). That is, it is determined whether or not the operator presses the operator associated with any finger. Here, when one of the operators of the operator devices 11 and 12 is pressed and finger information is input, the editor confirms whether the finger information input from the operator devices 11 and 12 is acceptable. A confirmation signal for this is output to the operator devices 11 and 12 (step S6). Here, the confirmation signal is a signal for causing the LED 11L or the LED 12L corresponding to the inputted finger information to emit light as described later. It should be noted that the finger information (for example, “the thumb of the left hand”) is displayed on the display screen of the PC 10 without outputting a confirmation signal to the operator device 11 so as to prompt the editor to confirm. Also good.
[0027]
Thereafter, it is determined whether or not the operator No. 0 of the operator devices 11 and 12, that is, the confirming operator is pressed (step S 7). Here, when the operator presses the 0th operator, the finger information input in step S5 is confirmed, and this finger information is written in the finger information writing area (step S8). If finger information has already been written in the finger information writing area, the finger information newly input from the operation device 11 or 12 is overwritten.
[0028]
Next, it is determined whether or not the editing process should be terminated (step S9). Here, when an editing end command is input from the editor or when input of finger information corresponding to the last note of the note sequence constituting the music is ended, it is determined that the editing process should be ended. . On the other hand, in other cases, the process returns to step S4, the note to be edited next is notified to the editor, and the process from step S5 onward is repeated. Here, the note to be edited next is usually the note next to the note in which the finger information is input in the note string constituting the music.
[0029]
A-2-2. Specific performance data editing method
The outline of the performance data editing process by the PC 10 has been described above. Hereinafter, the performance data editing when finger information is written in the MIDI data will be described in detail.
[0030]
(1) MIDI data
First, prior to the performance data editing method, which part of MIDI data is to be edited will be described. In addition to messages indicating note-on and note-off, MIDI data includes various messages. In this example, finger information is written in a control change message, which is an extended byte, and written in performance data. When the finger information is used, it is determined by associating with the polyphonic key pressure message which note corresponds to the control change message in which the finger information is written.
[0031]
Specifically, the control change message and the polyphonic key pressure message are data as shown in FIG. The number corresponding to the finger is written in the right part of the control change message in the figure ("f" in the figure). As numbers corresponding to the fingers, for example, 1 to 5 may be used in order from the thumb of the left hand, and 9 to D may be determined in order from the thumb of the right hand. “Bn 10” in the control change message indicates an extension byte.
[0032]
Here, the finger information may be preliminarily set by writing automatically (all thumbs etc.) in advance. In this case, the left hand and the right hand may be temporarily set such that the right hand is above a predetermined pitch and the left hand is below a predetermined pitch. For example, in the case of a piano, the lower sound than the 49 keys may be temporarily set by a method such as a left hand.
[0033]
The polyphonic key pressure message includes a note code, and the note to be edited can be specified from this note code. The polyphonic key pressure message describes information “2F” indicating the depth, and is used to create an aftertouch feeling. However, since this information is not normally used, in this example, the polyphonic key pressure message is used. Key pressure messages are used as data for note discrimination. Note that the note-on message of the MIDI data naturally includes a note code, so it may be used as data for note discrimination, but it will be changed to a finger (to be described later (after depressing the key with a finger). In the case of changing the finger to be pressed down to another finger while maintaining the depression), there is no note-on message corresponding to the control change message describing the finger information after the finger change, and the finger information after the finger change is described. It becomes impossible to determine which note the control change message corresponds to. Therefore, in this example, the polyphonic key pressure message is used as data for discriminating notes, and during fingering practice, the notes indicated by the polyphonic key pressure message are pressed with the finger indicated by the control change message. Inform the person.
[0034]
(2) Data editing method
Next, the performance data editing method using the operator devices 11 and 12 will be specifically described. In this example, by operating the operator devices 11 and 12, one note (one in the case of a piano) Of course, it is possible to input one finger information for a keystroke operation), but it is also possible to input two or more finger information for one note. This is because, in the case of a piano or the like, a single key may be simultaneously pressed with a plurality of fingers, and the same key pressing with such a plurality of fingers is taken into consideration. In the piano, after a key is depressed with a certain finger, a performance operation such as a finger change in which the depressed finger is changed to another finger while the depression is maintained may be performed. In this example, in consideration of this point, even when a plurality of pieces of finger information are input for one note, it is possible to distinguish between the same keystroke and finger change. Hereinafter, the finger information input operation and the operations of the PC 10, the operator devices 11 and 12 and the electronic piano 13 during input will be described with reference to FIG.
[0035]
First, when the performance data is read by the PC 10 and the finger information is input, the PC 10 issues a sound generation instruction for generating a musical sound corresponding to the note to be edited to the electronic piano 13. . Here, when finger information is described in the control change message of the read MIDI data, the PC 10 issues a light emission instruction of the LED 11L or LED 12L of the operation device corresponding to the finger information. In addition to this, a musical score may be displayed on the display screen of the PC 10 to indicate notes to be edited. As a result, the editor can know the note that is currently being edited, and can also know the finger information currently input to the note.
[0036]
In this way, the editor who has been notified of the note to be edited and the finger information currently input for the note is the No. 1 to No. 5 operators and No. 9 to No. 13 of the operator devices 11 and 12. By operating the operation element, finger information previously associated with the operation element is input to the PC 10. Here, when the editor depresses two operators, the PC 10 determines that the same key is pressed. When finger information is input from the operator devices 11 and 12 to the PC 10, the PC 10 stops the light emission instruction and the sound generation instruction that have been performed for notifying the editing object, and the operator device in order to prompt the editor to confirm. 11 and 12, the LED 11L or LED 12L corresponding to the finger information input by the editor is caused to emit light (if the same key is pressed, two LEDs are caused to emit light), and the generation of the musical sound that is currently being edited again is electronically recorded. The piano 13 is instructed. In this example, when three or more operators are pressed when finger information is input, the PC 10 performs processing for deleting the finger information currently described in the control change message. Therefore, in this example, it is not possible to input three or more finger information for one note.
[0037]
Thereafter, when the 0th operator of either of the operator devices 11 and 12 is pressed, the PC 10 determines the finger information inputted by the editor, writes it in the MIDI data control change message, and also plays the electronic piano. 13 is instructed to stop sound, and the operator devices 11 and 12 are instructed to turn off the LED. This completes the input of finger information for the note, and the finger information is written into the MIDI data as shown in FIG. In the figure, “90 kk vv” is a note-on message with a note number kk. FIG. 7A shows an example in which one finger information is written for one note, and FIG. 7B shows a case in which two finger information is written for one note, that is, the same keystroke. An example is shown. As shown in the figure, in the case of the same key press, there are two control change messages and polyphonic key pressure messages for one note-on message, and each finger information is written in each control change message. In this case, there may be only one polyphonic key pressure message.
[0038]
After the finger information is written in this way, the same operation is repeated for the next note to be edited. Here, the next note is determined based on the order of the note strings in the normal performance data, that is, the progression order of the music, but is set in advance for the operation of the PC 10 or the operator devices 11 and 12. It is also possible to fast forward or rewind a note to be edited by performing a special operation. Alternatively, a desired note may be searched and the note may be selected for editing.
[0039]
In the above description, the case where the finger information is input to the PC 10 by operating the operator devices 11 and 12 has been described. However, the finger information previously described in the MIDI data (notified to the editor by the LED). If it is not necessary to correct the information, the finger information input is not performed and the 0th operator is pressed as it is. In this case, the PC 10 does not correct the finger information and proceeds to an editing process for the next note.
[0040]
Next, a case where finger information for finger change is input will be described with reference to FIG. Also in this case, the note to be edited and the finger information currently described are notified to the editor by the PC 10 as described above. When inputting finger information for finger change, the editor notifies the PC 10 to that effect. Here, as this notification method, there is a method of performing a special operation on the operation device 11 or 12, for example, an operation of simultaneously pressing down the No. 0 operation device and another operation device. Further, a button or the like for notifying that a finger change is to be performed may be provided on the operator device 11 or 12, or the PC 10 may be directly operated to notify the finger change.
[0041]
After notifying the PC 10 of the finger change in this way, the editor first operates the operator corresponding to the first finger to input finger information to the PC 10. Thereafter, as described above, the PC 10 stops the light emission instruction and the sound generation instruction, and responds to the first finger information input from the editor to the operator devices 11 and 12 in order to prompt the editor to confirm. The LED 11L or LED 12L to be emitted is caused to emit light, and the electronic piano 13 is instructed again to generate a musical sound that is currently being edited.
[0042]
When the 0th operator of either of the operator devices 11 and 12 is pressed, the PC 10 determines the first finger information input from the editor and writes it in the control / change message of the MIDI data. In the case of finger change, the PC 10 does not give a sound stop instruction to the electronic piano 13 even if the 0th operator is pressed, continues sounding, and notifies the editor that the note to be edited has not changed. .
[0043]
In this state, the editor operates the operator devices 11 and 12 to input the second, that is, finger information after the finger change to the PC 10. After this, as in the case of the first finger information input, after the LED light emission and the sound generation of the electronic piano 13 are stopped, the LED light emission instruction corresponding to the finger information input for prompting confirmation and the editing target Gives pronunciation instructions corresponding to the notes. When the operator presses the 0th operator, the PC 10 determines the second finger information input from the editor and writes it in the control / change message of the MIDI data. In this case, simultaneously with the writing process, the electronic piano 13 is instructed to stop sound, and the operator devices 11 and 12 are instructed to turn off the LEDs. Then, MIDI data as shown in FIG. 7C is created. In this data, “Δt” is data indicating the time from the start of performance using the first finger until the finger is changed to the second finger. This is the editor when inputting finger information. May be input as appropriate, or a preset fixed value may be adopted.
In addition, when adopting a fixed value, since the finger change is generally made to press the key to be pressed next without difficulty, it is better to consider the timing of the next note-on event, For example, the timing of a predetermined ratio before the next note-on event or the time from the current note-on event to the next note-on event (for example, the middle of the current note-on event and the next note-on event), etc. do it.
[0044]
Here, comparing the data in which the finger information of the same key press shown in FIG. 7B is written with the data in which the finger information of the finger change shown in FIG. A message (figure of control change message and polyphonic key pressure message) in which finger information is written is before and after the note-on message. It is in. As a result, when MIDI data including finger information is used, it is possible to discriminate between finger change and the same keystroke.
[0045]
When finger information for finger change is input in this manner, the same operation is repeated for the next note to be edited.
[0046]
As described above, according to the performance data editing method according to the present embodiment, when finger information is input, it is possible to perform an easy operation such as pressing an operator associated with a desired finger in advance on the operator devices 11 and 12. Editing processing such as adding or correcting finger information to the performance data can be performed. In addition, the note to be edited is notified to the editor by the musical score display and the sound of the electronic piano 13, so that it is possible to reduce erroneous operations such as the editor performing incorrect editing.
The performance data to which the finger information is added in this way is provided for fingering training by, for example, the device described in Japanese Patent Application No. 11-180676.
[0047]
B. Second embodiment
Next, FIG. 9 shows an appearance of a system to which the performance data editing method according to the second embodiment of the present invention is applied. Note that in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0048]
As shown in FIG. 9, this system includes a PC 10 and an automatic piano (operator device, notification means) 90 connected to the PC 10 by a cable 90a. The automatic piano 90 is provided with an LED 91 corresponding to each key, and has a function of notifying a player of a key to be pressed by selectively causing the LED 91 to emit light based on performance data at the time of performance support. Yes.
[0049]
Here, FIG. 10 shows a configuration of a main part of the automatic piano 90. In the figure, reference numeral 1 is a key, and reference numeral 3 is an action for transmitting the movement of the key 1 to the hammer 2. Reference numeral 4 is a string hit by the hammer 2, and reference numeral 5 is a solenoid that drives the key 1. During automatic performance, when the plunger of the solenoid 5 protrudes, the key 1 rotates about the balance pin P and falls to the performer side. In conjunction with this, the action mechanism 3 operates, the damper 6 moves away from the string 4, and the hammer 2 rotates to strike the string 4. On the other hand, when the performer performs, the front end of the key 1 is pushed down by the performer, and the same action as described above occurs, and the string 4 is hit.
[0050]
Reference numeral 25 denotes a key sensor attached below the key 1, which detects the operation of the key 1 and outputs the detection result to the control unit 30. The control unit 30 controls each part of the automatic piano apparatus, and controls the driving of the solenoid 5 and the LED 91 via the solenoid drive circuit 31 and the light emission drive circuit 32 based on the performance data. In the present embodiment, the control unit 30 performs later-described control based on a control signal from the PC 10. When this automatic piano is in the performance support mode, the key 91 to be pressed is sequentially notified to the performer by selectively causing the LED 91 to emit light based on the performance data. On the other hand, at the time of automatic performance, the solenoid 5 is selectively driven based on the performance data, thereby hitting the desired string 4 and generating a musical tone as described above.
[0051]
In addition, this automatic piano is provided with a silencer mechanism having a stopper (not shown) that stops the movement of the action mechanism 3 immediately before the hammer 2 strikes the string 4, thereby enabling a silenced performance. Further, the control unit 30 supplies a control signal corresponding to the key pressing information supplied from the key sensor 25 to the sound source 33, and generates a musical sound signal corresponding to the key 1 on which the sound source 33 is pressed. This musical tone signal is supplied to the speaker 34 so that a musical tone corresponding to the key pressed by the performer can be generated.
[0052]
In the present embodiment, the performance data editing process is performed using a system in which the automatic piano 90 having the above functions and the PC 10 are connected. In this embodiment, the keyboard of the automatic piano 90 is used as an operator for inputting finger information instead of the operator devices 11 and 12 used in the first embodiment. For this reason, when entering the edit input mode, the PC 10 first performs control for assigning the left and right fingers and the 0 key for confirmation to the keyboard of the automatic piano 90. Here, FIG. 11 shows an example of assignment of a keyboard and each finger. In this example, the high-pitched portion of the keyboard is assigned as an operator for inputting finger information.
[0053]
The outline of the editing process after the assignment as described above is the same as that in the first embodiment (see FIG. 2), but the function of the automatic piano 90 is used in the method of notifying the user of the note to be edited. In the following, a specific performance data editing method using the automatic piano 90 will be described as an example of editing MIDI data in the same manner as in the first embodiment. I will explain to you.
[0054]
First, when performance data is read by the PC 10 and a finger information is entered, the keyboard of the automatic piano 90 is associated with each finger as described above and assigned as an operator for finger information input. Here, normally, the high-pitched portion of the keyboard is used as an operation element as described above. However, if the key 1 corresponding to the note to be edited is a key assigned as the operation element, the bass sound of the keyboard The key on the side is assigned as an operator and used. The assignment contents in this case are set in advance in the same manner as on the high sound side (see FIG. 11).
[0055]
FIG. 12 shows the operation of each part during performance data editing in time series. In the figure, “Solenoid Edit” and “LED Edit” indicate the solenoid and LED provided on the key 1 corresponding to the note to be edited, and “Solenoid Finger” and “LED Finger” are indicated in the finger information. The solenoid and LED provided on the key to be displayed are shown.
[0056]
When the assignment as described above is completed, the PC 10 notifies the editor of the note to be edited. Specifically, the key 1 corresponding to the note to be edited is pressed by the solenoid 5 under the control of the PC 10, and the LED 91 provided corresponding to the key is caused to emit light. The sound source 33 generates a musical sound signal corresponding to the note to be edited and is generated by the speaker 34. On the other hand, when finger information is described in advance in the performance data, a key 1 (hereinafter referred to as a key operator) assigned to an operator corresponding to the finger information is pressed by the solenoid 5, and The LED 91 corresponding to the key operator is caused to emit light. Thereby, the finger information currently described in the performance data can be notified to the editor. When the key operator corresponding to the finger information is pressed, in order to prevent confusion with the musical sound corresponding to the note to be edited, the sound is not generated, that is, the string is not struck by the pressing operation. It is preferable to drive the solenoid.
[0057]
When the editing target or the like is notified as described above, the editor presses the key operator corresponding to the finger to be input. This pressing operation is detected by the key sensor 25, and finger information is input to the PC 10. Here, when the editor depresses two operators, the PC 10 determines that the keys are the same keystroke and two finger information is input. When the finger information is input, the PC 10 stops the sound generation of the sound source 33. In addition, the pressing operation of the key operator corresponding to the finger information described in the performance data is stopped (key release), and the light emission of the LED 91 corresponding to the key operator is stopped.
[0058]
Then, the PC 10 prompts the editor to confirm the finger information input from the key sensor 25. More specifically, the key operator corresponding to the input finger information is pressed by the solenoid 5 and the LED 91 corresponding to the key operator is caused to emit light (in the case of the same key pressing, two finger information is supported). The two key operators and the LED 91 are to be driven). At the same time, the sound source 33 is instructed to generate a musical tone of the note to be edited.
[0059]
Thereafter, when the editor depresses a key operator assigned to No. 0 (hereinafter referred to as No. 0 key manipulator), this depressing operation is detected by the key sensor 25 and the confirmation information is input to the PC 10. When the confirmation information is input, the PC 10 confirms the finger information input by the editor and writes it in the MIDI data control / change message, as well as the key press operation by the solenoid 5, the tone generation by the sound source 33, and the light emission of the LED 91. Stop all. Thereby, the input of finger information for the note is completed, and the same operation is repeated for the next note to be edited.
[0060]
Here, the next note is determined based on the order of the note strings in the normal performance data, that is, the order of progression of the music. Is pressed, the finger information is written, and the next note to be edited is returned to the note immediately before the note edited at the present time. On the other hand, when the other key operator is operated without pressing the number 0 key operator for the confirmation information input, finger information is not input to the note to be edited. Moves the editing target to the next note. Also, if you perform special processing such as fast-forwarding or rewinding the note to be edited, or searching for the desired note and making that note the next editing target, it will be selected by that processing. The next note becomes the next edit target. Such special processing will be described later.
[0061]
Next, a case where finger information for finger change is input will be described with reference to FIG. Also in this case, the note to be edited and the finger information currently described are notified to the editor by the PC 10 as described above. Thereafter, the editor operates the key operator corresponding to the first finger to input finger information to the PC 10. Thereafter, the PC 10 stops the sound generation of the sound source 33 in the same manner as described above. Further, the pressing operation of the key operator corresponding to the finger information described in the performance data is stopped, and the light emission of the LED 91 corresponding to the key operator is stopped. The processing so far is the same as normal finger information input.
[0062]
Thereafter, when inputting finger information for changing the finger, the editor depresses the number 0 key operator and holds down the key 1 corresponding to the note currently being edited for a predetermined time. Then, the PC 10 confirms the finger information previously input, writes it in the MIDI data control / change message, and stops all the key pressing operations by the solenoid 5, the tone generation by the sound source 33, and the light emission of the LED 91. Here, although the key pressing operation by the solenoid 5 is stopped, the key sensor 25 detects that the key is pressed because the editor continues to press the key. When the key press information of the key 1 corresponding to the editing target is input together with the key No. 0 in this way, the PC 10 determines that the finger is changed.
[0063]
Then, the PC 10 causes the tone generator 33 to generate a musical tone to be edited (the same musical tone because it is the same note), and notifies the editor of the editing target. When the second finger information for finger change is described in the performance data in advance, the key operator corresponding to the finger information is pressed by the solenoid 5 and the LED 91 corresponding to the key operator is pressed. To emit light.
[0064]
The editor presses the key operator corresponding to the finger to be input as the second finger information for finger change. This pressing operation is detected by the key sensor 25 and second finger information is input to the PC 10. When the second finger information is input, the PC 10 stops the sound generation of the sound source 33 in the same manner as when the first finger information is input. Further, the pressing operation of the key operator corresponding to the finger information described in the performance data is stopped, and the light emission of the LED 91 corresponding to the key operator is stopped. Then, the PC 10 prompts the editor to confirm the second finger information input from the key sensor 25 as in the case of the first finger information.
[0065]
Thereafter, when the editor depresses the number 0 key operator, the confirmation information is input from the key sensor 25 to the PC 10. When the confirmation information is input, the PC 10 confirms the second finger information input by the editor, writes it in the MIDI data control change message, presses the key 5 with the solenoid 5, generates the musical tone with the sound source 33, And all the light emission of LED91 is stopped. As a result, the input of the second finger information for the note, that is, the input of the finger information for the finger change is completed, and the process proceeds to the editing process for the next note to be edited. The MIDI data edited in this way is the same as that in the first embodiment (see FIG. 7).
[0066]
As a mode of finger change, after pressing a certain key (referred to as key A) with an index finger, the other key (referred to as key B) is pressed with a little finger, and at the same time as pressing start of pressing key B, It is also conceivable to change to pressing with the thumb while maintaining the pressed state of the key A that has been pressed. In such a case, first, information indicating the index finger is input as finger information corresponding to the key A in the performance data, and then the 0th key operator is pressed to be confirmed. Next, after inputting the little finger as the finger information corresponding to the key B, if the key A is pressed without pressing the No. 0 key operator, the PC 10 shifts to waiting for finger information input for the key A. Thereafter, if information indicating the thumb is input as finger information for the key A and the number 0 key operator is pressed, the finger information for changing the finger is input without inputting Δt indicating the above-mentioned finger changing timing. Can do.
[0067]
Next, a description will be given of a method of performing special processing such as fast-forward processing, fast-rewind processing, and search processing for searching for a desired note from a note string. In this example, by operating the key operator assigned to the keyboard of the automatic piano 90 as described above in accordance with a preset procedure, the PC 10 is caused to execute the fast forward process, the fast reverse process, the search process, and the like. be able to. Hereinafter, an example of an operation procedure when performing such special processing will be described.
[0068]
First, when fast-forwarding processing is performed, in the above-described finger information input operation, after pressing the number 0 key operator and inputting the confirmation information to the PC 10, the key is once released and the number 0 key operator is pressed again. If held in the pressed state, the note to be edited is fast-forwarded while the number 0 key operator is held in the pressed state, that is, sequentially changed according to the order of the musical note string. At this time, every time the note to be edited is changed, the key 1 corresponding to the note to be edited is pressed by the solenoid 5 and the LED 91 corresponding to the key 1 is caused to emit light. In addition, a tone corresponding to the note to be edited is generated by the sound source 33. As a result, the editor is notified of the editing target at that time. The editor may release the 0th key operator when a desired note is to be edited based on such notification contents.
[0069]
Next, a case where the fast reverse process is performed will be described. As described above, in this example, the edit target is returned to the previous note by double-clicking the 0th key operator when inputting the confirmation information. When fast rewinding is performed, after double-clicking in this way, the note number to be edited is changed in the direction opposite to the progression of the music by pressing and holding the number 0 key operator again. In this case as well, every time the editing target is changed as in the fast-forward process, the editing target at that time is notified to the editor by pressing the solenoid 5 or the like.
[0070]
Next, a case where search processing is performed will be described. When performing the search process, the editor holds down the key 1 corresponding to the note to be searched among the keys of the automatic piano 90. In this way, when the key 1 other than the key operator is pressed, the PC 10 performs a search process. Then, the music is searched according to the progression of music until a note corresponding to the key 1 held down by the editor (hereinafter referred to as a search note) is searched. When a search note is searched, the search process is terminated at that time, and a finger information input waiting state for the search note is entered. Also in this case, the note to be edited is changed in accordance with the order of the note string until the search note is searched. Every time the change is made, the edit subject is changed to the editor by sound generation, key pressing by the solenoid 5, or the like. Informed. Note that, as described above, when the key pressing state is maintained even after a predetermined time has elapsed after the search process is completed and the finger information input is waited, the search process is started again.
[0071]
On the other hand, when double-clicking the number 0 key operator when entering the confirmation information and holding down the key 1 corresponding to the note to be searched, the edit target is changed in the direction opposite to the progress of the music, and the search note is searched. Process. When a search note is searched, the search process is terminated at that time, and a finger information input waiting state for the search note is entered.
[0072]
If a search note is not searched after a lapse of a predetermined time from the start of the search process described above, a high-speed search process may be automatically performed. When this high-speed search process is performed, only the generation of a musical tone by the sound source 33 and the light emission of the LED 91 are performed as notification of the edit target performed every time a note is changed, and the key pressing is not performed by the solenoid 5. This is because when the edit target is changed at high speed, the operation of the solenoid 5 cannot catch up with the change of the edit target.
[0073]
According to the performance data editing method according to the present embodiment, finger information is added to the performance data by an easy operation such as pressing a key previously associated with a desired finger using the keyboard of the automatic piano 90, or Editing processing such as correction can be performed. In addition, the solenoid 5 and the LED 91 indicate the key corresponding to the note to be edited, and when the musical tone is generated, the note to be edited is notified to the editor. It is possible to reduce erroneous operations such as going. In addition, since the keyboard of the automatic piano 90 is used as an operator, there is no need to newly provide an operator device. In addition, execution of processes such as fast forward, fast reverse, and search can be instructed using a finger information input operator.
