Abstract

PROBLEM TO BE SOLVED: To provide a performance training apparatus and a performance training method for training a performance operation by guiding a key touch speed and the timing of a detouch operation in hearing sensation. SOLUTION: When a key whose touch is guided is touched at a speed which deviates from an appropriate range on the basis of an even EVT read synchronizing with the progress of a piece of music, for example, a pitched up beep sound is emitted when a key touch speed is too fast, and a pitched down beep sound is emitted when a key touch speed is too slow, to train a player to key touch strength in hearing sensation. Moreover, when the detouch is too fast, sounding is continued until it reaches appropriate detouch timing, is muffles upon reaching the detouch timing. When the detouch is too slow, a beep sound whose volume increases as the detouch operation is delayed is emitted. Thus, the player is trained in hearing sensation for the key touch.

Hereinafter, the operation of the main routine will be described first with reference to FIG. 3 as the overall operation, and then the operation of each processing routine called in the main routine will be described.

Operation of Main Routine When the power is turned on in the embodiment having the above configuration, the CPU 5
Reads a predetermined control program from the ROM 6, loads it into itself, executes the main routine shown in FIG. 3, and proceeds to step SA1. In step SA1, RA
Initialization for resetting various registers and flags stored in M7 and setting initial values is performed. Next, in step SA2, a corresponding switch process is executed based on the switch event generated by the panel switch group 3. For example, a process of selecting a tune to be taught to perform according to the operation of the tune selection switch or instructing the start of the training according to the ON operation of the start switch is executed. Then, in step SA3, a performance guide process for performing a performance lesson is performed in accordance with the music data of the selected music.
Then, keyboard processing for instructing the sound source 8 to sound / mute the sound is performed in response to the key press / release operation. Thereafter, steps SA2 to SA4 are repeated until the power is turned off.

Operation of Timer Interrupt Processing Routine When the start switch is turned on, the interrupt mask is released by the switch processing described later. Thus, the CPU 5 executes the timer interrupt process shown in FIG. 4 at regular intervals, and counts (accumulates) the timer clock by incrementing the timer counter T in step SB1.

Operation of Switch Processing Routine When the switch processing routine shown in the figure is executed via the above-described step SA2, the CPU 5 advances the processing to step SC1, and first determines whether or not the guide switch has been turned on. If the guide switch is not turned on, the determination result is “NO”, and the process proceeds to step SC3. If the guide switch is turned on, the determination result is “YES”, and the process proceeds to step SC2. This routine is completed once by setting "1" to the flag GF.

Next, in step SC3, it is determined whether or not the start switch has been turned on. If the start switch has not been turned on, the determination result is "NO", the process proceeds to step SC4, and after performing other switch processing, this routine is completed. On the other hand, when the start switch is turned on, the result of the determination in step SC3 is “YES”, and the flow proceeds to step SC5. In step SC5, the start flag STF is bit-inverted. The start flag STF indicates whether or not to start the performance training operation. When the start flag STF is "1", it indicates the start, and when it is "0", it indicates the end.

In step SC6, it is determined whether or not the bit-inverted start flag STF is "1", that is, whether or not the performance learning operation has started. here,
When the start flag STF is "0", the determination result is "NO", the process proceeds to step SC7, and an interrupt mask is applied to prohibit the timer interrupt process described above. On the other hand, the instruction to turn off the light emitting means 2a is issued to end the performance learning operation.

On the other hand, when the start flag STF is "1", the result of the judgment in step SC6 is "Y".
ES ”, the process proceeds to Step SC9, and the pointer register AD is reset to zero.
At 10 the ROM is set according to the value of the pointer register AD
6 to the song data (AD), that is, the first event EV
T is read and stored in a temporary register. Next, in step SC11, "1" is set to a flag TT indicating that the idle hit period (described later). Then, in step SC12, the timer counter T is reset to zero, and then in step SC13, the timer interrupt prohibition is released. Thus, the above-described timer interrupt processing (see FIG. 5) is executed at regular intervals.

Operation of Performance Guide Processing Routine Next, the operation of the performance guide processing routine will be described with reference to FIGS. Step SA3 described above (FIG. 3
When the performance guide processing routine shown in FIG. 6 is executed through the CPU 5), the CPU 5 advances the processing to step SD1.
It is determined whether the start flag STF is "1", that is, whether or not the performance training operation has been started. Here, if the performance learning operation is stopped, the determination result is “NO”, and this routine is completed without performing any processing. However, if the performance learning operation is started, the determination result is “YES”. And the process proceeds to the next Step SD2. In step SD2, it is determined whether or not the flag TT is "1", that is, whether or not the idle hit period is performed after the start switch is turned on. The idle period is a period from when the start switch is turned on to when the performance learning operation is actually started, and can be arbitrarily set in advance in units of beats, for example, a period of four beats.

If it is during the idle shot period, the determination result is "YES", and the flow advances to step SD3. In step SD3, it is determined whether or not the blank shot period is completed. If the blank shot period is still in progress, the determination result is “NO”,
Proceed to step SD4. In step SD4, the generation of an idle sound corresponding to the currently set reproduction tempo is determined by the sound source 8
In the next step SD5, the light emitting means 2a of the key corresponding to the note number NN in the head event EVT (1) which has already been read is set to the head event EVT (1).
The key press guide unit 2 is instructed to perform the blinking drive with the light emission intensity corresponding to the middle velocity VEL, and the present routine is completed.
As described above, after the start switch is turned on, during the idling period prior to the start of the performance learning operation, the light emitting means 2a of the key to be played first is caused to emit the idling sound in synchronization with the reproduction tempo and the velocity VEL. Flashing drive at a light emission intensity corresponding to the first performance operation.

When the idle time is completed, the result of the determination at step SD3 becomes "YES", the flag TT is reset to zero to indicate that the idle time is completed, and the routine is once completed. Then, when the present routine is executed again via the main routine, the determination result of the above-mentioned step SD2 becomes “NO” by resetting the flag TT to zero, and the process proceeds to step SD7. In step SD7, it is determined whether or not the event (AD) read from the ROM 6 according to the value of the pointer register AD is the END data indicating the end of the music, that is, whether or not the reproduction of the music data has been completed. When the reproduction of the music data is completed, the determination result is "YES", the process proceeds to step SD8, the start flag STF is reset to zero, the timer interrupt is prohibited in step SD9, and the key press guide section is performed in step SD10. The second light emitting means 2a is turned off to end the performance training operation.

On the other hand, if the reproduction of the music data has not been completed, the result of the determination in step SD7 is "NO",
Proceeding to step SD11 shown in FIG. 7, it is determined whether or not the event (AD) read in accordance with the pointer register AD is an ON event. If it is an ON event, the determination result is "YES", and the process proceeds to step SD12 to instruct the key press guide unit 2 to turn on the light emitting unit 2a of the key corresponding to the note number NN of the current ON event. Next, at step SD13, the next ON event is searched from the music data, and the key press guide unit 2 is instructed to blink the light emitting means 2a of the key corresponding to the note number NN of the event, and thereafter, the pointer register AD
Is incremented and the step is advanced to complete the present routine.

On the other hand, the read event (A
If D) is an off event, the result of the determination in step SD11 is "NO", and the flow advances to step SD15.
In step SD15, the key press guide unit 2 is instructed to turn off the light emitting unit 2a of the key corresponding to the note number NN of the current off event. Next, in step SD16,
The next ON event is searched from the music data, and the key press guide unit 2 is instructed to turn on the light emitting means 2a of the key corresponding to the note number NN of the event. Next step SD
At 17, the next ON event is searched from the music data, and the key press guide unit 2 is instructed to blink the light emitting means 2a of the key corresponding to the note number NN of the event. Pointer pointer A
This routine is completed by incrementing D.

As described above, in the performance guide processing, during the idle period from when the start switch is turned on to when the performance learning operation is actually started, the idle sound is generated while synchronizing with the reproduction tempo. Light emitting means 2 of key to play first
a is driven to blink at a light emission intensity corresponding to the velocity VEL to guide the first performance operation, and after the idling period is completed, the light emitting means 2a of the key to be played is turned on based on the event EVT read out in synchronization with the reproduction tempo. On the other hand, while flashing the light emitting means 2a of the key to be played next, the light emitting means 2a of the key to be released is turned off, and the position of the key to be operated and the key operation timing are visually guided so that the performance is taught. It has become.

Operation of Keyboard Processing Routine Next, the operation of the keyboard processing routine will be described with reference to FIG. When the keyboard processing routine shown in FIG. 8 is executed through the above-described step SA4 (see FIG. 3), the CPU
In step SE1, key scanning is performed to detect a key event by proceeding to step SE1, and in step SE2, the presence or absence of a key change (key event) is determined based on the result of the key scanning. Here, when no key event has occurred, that is, when no key operation has been performed, this routine is completed without performing any processing. On the other hand, if a key-on event has occurred due to a key-depressing operation, an on-event process from step SE3 is executed, and if a key-off event has occurred due to a key-release operation, an off-event process from step SE11 is executed. Hereinafter, the on-event processing and the off-event processing will be described.

(A) On-event processing When a key-on event occurs due to a key-depressing operation, the process proceeds to step SE3, where the key number of the depressed key is stored in the register KN, and in the subsequent step SE4, it is determined whether or not the flag GF is "1". That is, it is determined whether the vehicle is in the guide mode. If the mode is not the guide mode, the determination result is “NO”, the process proceeds to step SE10, and the tone of the pitch corresponding to the key number stored in the register KN is set to the volume according to the velocity generated according to the key pressing operation. The sound source 8 is instructed to generate a sound, and this routine is completed.

On the other hand, if the vehicle is in the guide mode, the result of determination in step SE4 is "YES", and
Go to E5. In step SE5, it is determined whether or not the key number KN matches the note number NN of the on event, that is, whether or not the key whose key is being guided has been pressed. Here, if a key different from the key whose key is guided is erroneously depressed, the determination result is "NO", the process proceeds to step SE6, and the sound source 8 is instructed to sound a warning sound and erroneously depressed. Report the key. Then, in the next step SE9,
In order to generate a musical tone corresponding to the key whose key is depressed, the tone generator 8 is instructed to emit a musical tone in accordance with the note number NN and the velocity VEL of the note-on event, thereby completing this routine.

On the other hand, if the key whose key is guided is pressed, the result of determination in step SE5 is "YES", and the process proceeds to step SE7. In step SE7, the velocity VEL defined by the note-on event
Then, it is determined whether or not the value of the velocity generated in response to the key depression is within a preset allowable range.
Here, if the value of the velocity generated in response to the key depression is within the allowable range, the determination result is “YES”, and
In this case, the process proceeds to step SE10 described above, instructs the sound source 8 to generate a tone having a pitch corresponding to the key number KN at a volume according to the velocity generated in response to the key depression operation, and completes this routine. Let it.

On the other hand, if the velocity value generated in response to the key depression does not fall within the allowable range, the determination result is "NO", and the flow advances to step SE8. Step SE
8, the warning sound changes according to the error from the allowable range,
For example, if the key pressing speed is too fast and a velocity exceeding the allowable range occurs, an instruction is issued to generate a warning sound pitched up according to the excess, while the velocity at which the key pressing speed is too low and falls below the allowable range , An instruction is issued to sound a warning sound pitched down according to the shortfall. After learning the key pressing speed auditorily, the routine is completed through the above-described step SE10.

(B) Off-event processing When a key-off event occurs due to a key release operation, the flow advances to step SE11 to store the key number of the released key in the register KN.
It is determined whether or not F is “1”, that is, whether or not F is in the guide mode. If not in the guide mode, the determination result is "NO", the process proceeds to step SE17, and the sound source 8 is instructed to mute the musical tone having the pitch corresponding to the key number stored in the register KN, thereby completing this routine. .

On the other hand, if the mode is the guide mode, the result of determination in step SE12 is "YES", and the flow advances to step SE13. In step SE13, it is determined whether or not the key is released before the allowable time. Key release before the allowed time is
It indicates the range of Δt before and after the key release timing indicated by the note-off event of the music data, and the Δt is a preset time value. If the key release is too early, the result of this determination is "YES", and the process proceeds to step SE15. In step SE15, the tone generation is instructed to continue sounding until the key release timing represented by the note-off event is reached, and when the key release timing is reached, the tone generator 8 is silenced at the pitch corresponding to the key number stored in the register KN. To complete this routine.

On the other hand, if the key is not released before the permissible time, the result of determination in step SE13 is "NO", and the flow advances to step SE14. In step SE14,
It is determined whether the key is released within the allowable time. If the key release operation is performed at an appropriate timing, the determination result is “Y
ES ”, and the register KN is set via the step SE17.
The sound source 8 is instructed to mute the musical tone having the pitch corresponding to the key number stored in the subroutine, thereby completing this routine.

On the other hand, if the key is not released within the allowable time, that is, if the key release is too late, the result of the determination in step SE14 is "NO", and the process proceeds to step SE16. In step SE16, the sound source 8 is instructed to emit a warning sound whose volume changes in accordance with the delay amount, for example, a warning sound whose volume increases as the key release operation is delayed, and thus, the key release timing is taught audibly. After that, the above-described step SE
At step 17, the sound source 8 is instructed to mute the tone having the pitch corresponding to the key number stored in the register KN, thereby completing this routine.

As described above, according to the present embodiment, based on the event EVT, the light emitting means 2a of the key to be played is turned on, while the light emitting means 2a of the next key to be played is blinked, and the key to be released is blinked. By turning off the light emitting means 2a, the position of the key to be key operated and the key operation timing are visually guided to perform the performance training, and when a key different from the key guided is erroneously pressed. Generates an appropriate tone corresponding to the key that has been guided to be depressed after issuing a warning sound to notify the erroneously depressed key. When a key is depressed at a speed outside the proper range, for example, if the key depressing speed is too fast, a pitched-up warning sound is issued, and if it is too slow, a pitched-down warning sound is emitted and the player is depressed audibly. Train your strength. Furthermore, if the key release is too early, the sound is continued until the proper key release timing is reached, and then the sound is muted when the key release timing is reached, and if the key release is too late, the key release operation is performed. As the sound is delayed, a warning sound that increases the volume is issued, and the player is taught to learn the key pressing strength audibly.

In the above-described embodiment, when a key different from the key whose key is guided is erroneously pressed, a warning sound for notifying the erroneous key is emitted. A tone corresponding to the pitch of a depressed key may be generated in a tone that indicates an erroneously pressed key, or an effect (for example, vibrato or the like) that indicates an erroneously depressed key may be provided. further,
In the present embodiment, when the key pressing speed deviates from the appropriate range, the warning sound is pitched up or down according to the generated velocity. However, the present invention is not limited to this.
The pitch of the pressed key may be shifted in accordance with a velocity value that deviates from the appropriate range, or a predetermined effect may be applied to notify the player of an incorrect key pressing speed.

In addition, in this embodiment, if the key release is too early, the sound generation is continued until the proper key release timing is reached. Alternatively, the designated tone color may be continued until the proper key release timing is reached. You can continue the pronunciation with a different tone from
A mode may be adopted in which a predetermined effect is applied to continue sounding, and the player is notified that the key release timing is too early. Further, in the present embodiment, when the key release is too late, a warning sound in which the volume increases as the key release operation is delayed is issued,
Alternatively, after the appropriate key release timing, until the key release operation is performed, the key release may be performed with a tone different from the tone that has been previously generated, or may be generated with a predetermined effect and generated. A mode in which the timing is too late is notified to the player.
