Description

  The present invention relates to a performance operation training device and a program for performance operation training processing.

Conventionally, various techniques for performing a keyboard instrument more efficiently have been proposed. For example, in Patent Document 1, a light emitting element is provided corresponding to each key, and a light emitting element corresponding to a key to be depressed when playing a designated song is sequentially turned on in accordance with a timing at which the key is to be depressed. Thus, a configuration is disclosed in which the performer recognizes which key should be pressed at which timing.
By applying such a configuration, the performer can recognize the key pressing order and key pressing timing for performing the music, and can perform the music faster.

Furthermore, Patent Document 2 discloses a configuration that can display not only the key pressing order and key pressing timing but also the fingers used for key pressing.
By using such a configuration, it becomes possible to recognize a fingering operation necessary for the performance of a song, and it becomes possible to practice a more serious performance more efficiently.
Japanese Patent Publication No. 01-053469 Japanese Utility Model Publication No. 03-089467

  The performance training apparatus having the configuration as disclosed in Patent Documents 1 and 2 is extremely effective if it is intended to be able to perform only the music given as a performance practice subject. However, even if a song given as this task can be played, there is no guarantee that other songs with different key pressing order, timing, and fingering can be played.

In particular, with regard to fingering and finger usage necessary for performance, there are many cases where strengths and weaknesses are divided according to the performer or the designated song.
This is due to individual differences in the motor ability of each finger. That is, some people are very poor at moving the middle finger, while others are not good at moving the ring finger.
This poor finger cannot be moved at the speed intended by the performer, and if it is forced to move, it often moves to other fingers. That is, if the finger intended by the performer is released, a situation occurs in which the key release operation is performed in conjunction with the other fingers that must maintain the key press.

To play a keyboard instrument, you must be able to freely press and release all your fingers, and if you are not good at using specific fingers, you must overcome it. Performance does not improve.
Furthermore, in order to overcome this poor finger operation, it is only necessary to improve the exercise ability by moving only the weak finger. However, it is nothing but painful and long-lasting to train to move only the poor fingers monotonously without meaning. For this reason, the device which can aim at the improvement of an athletic ability, without being conscious of much that it is training of such a finger was desired.

In addition, playing a keyboard instrument using fingers has proven to be very effective in activating the brain.
This is because the brain recognizes which finger has to be moved and commands the finger to move it, which in turn stimulates the brain. The more you do, the more stimulation you give to the brain.

  In particular, of all the fingers, one finger keeps the state as it is and only the other fingers perform designated movements, not only helps to improve the exercise ability of each finger, It is known that a large stimulus is given to the brain and it is very effective for brain activation.

  It is an object of the present invention to provide a performance training apparatus that can improve the exercise ability of each finger necessary for playing a keyboard instrument and is also useful for activating the brain.

  In order to achieve the above object, the performance training device of the present invention includes: a first determination unit configured to determine whether or not a plurality of predetermined keys corresponding to each finger are pressed on the keyboard; First at least one key is sequentially specified from the pressed keys, and at least one key sequentially specified by the first instruction means and the first instruction means for instructing the designated key at a predetermined timing A second discriminating unit that discriminates whether or not the key has been released at the designated timing, and every time the second discriminating unit discriminates that the designated key has been released, A third discriminating unit that discriminates whether or not any of the keys that have been keyed has been released; and when it is determined that the key has been released by the third discriminating unit, The key specified by the instruction means After the key is specified by the means and the specifying means, any one of the specified keys is randomly specified at a predetermined timing in a state where all of the plurality of predetermined keys are pressed. Storage means for storing music data comprising a sequence of events for instructing sound generation each time the at least one key instructed by the second instruction means is released and pressed. And reading means for sequentially reading the events and sending the read events to the connected sound source means.

  In addition, the performance operation training device further includes a key pressing instruction means for instructing a plurality of predetermined keys corresponding to each finger on the keyboard, and the first determination means includes the key pressing instruction. It is desirable to determine whether or not all of the plurality of keys indicated by the instruction means have been pressed.

The performance operation training apparatus changes the predetermined timing instructed by the instruction unit after instructing all the combinations of the two keys by the instruction unit, and the instruction unit, the second It is preferable to further include a control unit that causes the determination unit and the instruction control unit to repeatedly perform the same operation.
Furthermore, it is desirable that the control means advance the predetermined timing each time the repeated operation is performed.

  The performance operation training processing program of the present invention includes a first determination step of determining whether or not all of a plurality of predetermined keys corresponding to each finger are pressed on the computer on the keyboard; A first instruction step for sequentially specifying at least one key from the pressed keys, and indicating the specified key at a predetermined timing; and at least one key sequentially specified by the first instruction step A second determination step for determining whether or not the key has been released at the specified timing, and every time the second determination step determines that the specified key has been released, A third determining step for determining whether or not any of the keys being released has been released; and if it is determined that the key has been released by the third determining step, the released key and the first A specifying step of specifying the key instructed by the instructing means, and after the key is specified in this specifying step, the plurality of predetermined keys are all depressed and the specified key A second instruction step for randomly instructing one of them at a predetermined timing, and instructing sound generation each time the at least one key instructed in the second instruction step is released and pressed A reading step of sequentially reading events from a storage means for storing song data comprising a series of events and sending the read events to connected sound source means is executed.

  According to the present invention, after determining whether or not all of a plurality of predetermined keys corresponding to each finger are depressed on the keyboard, at least one key is sequentially designated from the depressed keys. At the same time, the designated key is designated at a predetermined timing. Then, it is determined whether or not at least one of the sequentially specified keys is released at the specified timing, and every time it is determined that the specified key is released, another key is pressed. It is determined whether or not one of the keys being released has been released, and if it is determined that the key has been released, the key that has been released and the instructed key are identified. After this key is specified, any one of the specified keys is randomly specified at a predetermined timing in a state where all of the plurality of predetermined keys are pressed, and the specified key Each time the key is released and pressed, the event is sequentially read out from the storage means for storing the song data consisting of a sequence of events for instructing sound generation, and the read event is sent to the connected sound source means.

  As a result, the performer can recognize which finger's athletic ability needs to be improved, and repeat this series of actions to improve the poor athletic ability of the finger. And by simply playing a song that best suits the athletic ability of the poor fingers, training can be performed without special awareness of weak finger luck, etc., greatly increasing the psychological burden on the performer. To reduce.

  Furthermore, it is possible to give stimulation to the brain by repeating a series of actions such that one of the fingers holds the key pressed state and only the other fingers are released. It becomes possible to promote the activation of the brain.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an internal configuration of a keyboard instrument to which a performance training apparatus according to an embodiment of the present invention is applied.

  In FIG. 1, a CPU 1, a program ROM 2, a work RAM 3, a song data ROM 4, a display unit 5, a keyboard 6, an LED group 7, a SW unit 8 and a sound source 9 are connected by a common bus line. The CPU 1 performs processing of the entire keyboard instrument based on the program stored in the program ROM 2. In addition to the program for controlling the processing performed by the CPU 1, the program ROM 2 also stores a key number for indicating a key to be depressed with all fingers first.

  The work RAM 3 temporarily stores data necessary for processing performed by the CPU 1, and the data structure thereof includes initial finger position data F (1) to F (5), a timer as shown in FIG. It has an area for storing time data T (1) to T (a), and further area data AREA (1) to AREA (a).

The initial finger position data F (1) to F (5) stores the key number to be pressed by each finger when the key is first pressed on the keyboard using all the right fingers. It is transferred from the ROM 2.
1 to 5 represent finger numbers. In the present embodiment, the right hand thumb is 1, the right hand index finger is 2, the right hand middle finger is 3, the right hand ring finger is 4, and the right hand little finger is 5.

In the present invention, the timer time data T (1) to T (a) is instructed to sequentially release any two fingers while all the right fingers are depressed. This is an area for storing operation timing.
In the present embodiment, since the key release operation is configured to be performed a plurality of times while advancing the timing, a plurality of types of timer time data are prepared.

  Area data AREA (1) to AREA (a) are provided corresponding to each area of the timer time data described above. If the key release operation cannot be performed at the instructed timing, the area data are pressed by these two fingers. This is an area for storing key number combinations.

The song data ROM 4 stores a plurality of song data (1) to (M) to be practiced. FIG. 3 is a diagram showing the data structure of the song data ROM 4. The stored music data is composed of a combination of an event indicating a key depression (note-on) and a time indicating an occurrence timing between the events.
Each event includes an event type for identifying the type of event (key press, key release), a note number (key number) indicating the key pressed or key released, and velocity.

  Returning to FIG. 1, the display unit 5 is composed of a display element such as a liquid crystal. In this embodiment, the display unit 5 displays fingers corresponding to two keys that could not be released as instructed.

  The keyboard 6 is used for performance operation, and each LED of the LED group 7 is arranged corresponding to each key of the keyboard 6. By turning on this LED, the player is prompted to press the key on which the lighted LED is arranged, and by turning off the LED, the player is prompted to release the key.

  The SW unit 8 includes a switch for switching the operation mode of the keyboard instrument, and the sound source 9 generates / stops a musical tone signal based on a note-on / note-off event generated by pressing / releasing the key 6 The generated tone signal is supplied to the sound generation circuit 10 to generate a tone.

Next, operation | movement of this apparatus is demonstrated using the flowchart of CPU1 of FIGS.
FIG. 4 is an overall flowchart. First, when the power is turned on, initialization processing is performed, and the contents of the registers in the CPU 1 and the work RAM 3 are initialized (step S401). Next, the process proceeds to step S402, where it is determined whether or not the current mode is the normal mode. If the current mode is the normal mode, the normal mode process (step S403) is executed.

If it is not the normal mode, it is determined whether or not it is the training mode (step S404), and if it is the training mode, the training mode process (step S405) is executed.
If it is not the training mode, it is determined whether or not it is the music guide mode (step S406), and if it is the music guide mode, the guide mode process (step S407) is executed.
If it is not the music guide mode, after the execution of the normal mode process (step S403), the training mode process (step S405), and the music guide mode process (step S407), the process returns to step S402 again.

FIG. 5 is a subroutine of the normal mode process (step S403) of FIG.
First, it is determined whether or not any key on the keyboard 6 has changed (step S501). If the key change is ON (key pressing), the process proceeds to step S502, a note-on event is generated based on the key number of the key pressed, the key pressing strength (velocity), etc., and the process proceeds to step S503. Send to sound source 6.
If the key change is off (key release), the process proceeds to step S504, a note-off event is generated based on the key number of the pressed key, and the process proceeds to step S503 to be sent to the sound source 6. .
The sound source 6 starts or stops the generation of the musical tone signal based on the sent event.

  After the process of step S503, or when it is determined that there is no key change in step S501, it is determined whether or not a mode change instruction such as an operation of the SW unit 8 has been given (step S505). If there is a mode change instruction, a mode change process corresponding to the instruction is performed (step S506), and this process is exited. If there is no instruction to change the mode, the process is exited as it is.

6 to 8 show a subroutine of the training mode process (step S405) of FIG.
First, the contents of AREA () in the work RAM 3 are cleared (step S601). Next, 1 is set to the pointer a (step S602).

Then, the initial finger position data stored in the program ROM 2 is stored in the areas F (1) to F (5) in the work RAM 3 (step S603).
In the present embodiment, the keyboard keys are first depressed with all the right hand fingers. For this reason, the initial finger position data is composed of the key numbers of the five keys to be pressed.
Next, the LEDs of the LED group 7 corresponding to the keys having the key numbers stored in F (1) to F (5) in the work RAM 3 are turned on (step S604).

  Then, it is determined whether or not all the keys instructed by the lighting of this LED have been depressed (step S605). If it is determined that all keys have been depressed, the process advances to step S606 to set the value of the pointer n for designating the finger number to 1.

  In step S607, the LED corresponding to the key having the key number stored in F (n) is turned off, and the timer in the CPU 1 starts counting (step S608).

  Thereafter, the process proceeds to step S609 in FIG. 7, and it is determined whether or not the time counted by the timer has passed the timer time T (a) stored in the work RAM 3 designated with the pointer a as an argument. If it is determined that it has not elapsed, it is determined whether or not the key of the key number stored in F (n) is released and pressed (step S610), and it is determined that the key is released and pressed. If it is determined, it is determined whether any key pressed other than the key corresponding to F (n) has been released (step S611). If a key release is detected here, that is, in conjunction with an operation in which a key whose LED is turned off is released and pressed, the other keys released are released. It is determined whether or not a plurality of keys are present (step S612).

If it is determined in step S612 that there are a plurality of keys released, one of the keys released is selected (step S613), and the process proceeds to step S614. If there are not more than one, the process proceeds directly to step S614.
In step S614, the number of the finger that has pressed the key is stored in the register m from the number of the released key (that is, any one of F (1) to F (5)). Then, the value of m and the value of the designated finger number n are stored in the area AREA (a) in the work RAM 3 designated with the pointer a as an argument (step S615).

Thereafter, the process proceeds to step S616, and it is determined whether there is any other key released. If there is still a key that has been released, the process returns to step S612, and the processes of steps S612 to S615 are repeated for the remaining keys that have been released.
On the other hand, if there is no other released key, the process proceeds to step S617.

  Similarly, when it is determined in step S609 that the timer count time has passed the timer time (a), or in step S611 described above, other than the key corresponding to F (n). If it is determined that any of the keys being pressed is not released, the process proceeds to step S617.

  In step S617, the timer stops counting, and the LED corresponding to the key with the key number stored in F (n) is turned off (step S618). Subsequently, the value of the pointer n representing the finger number is incremented (step S619), and it is determined whether or not the value of n exceeds 5 (step S620). If it is determined that it has not exceeded, the process returns to step S607, and the processes of steps S607 to S619 are performed again.

  By repeating this process, when n = 1 to 5, that is, when each finger from the thumb to the little finger is sequentially specified, the key is released from the key pressing state, and the key is pressed again, the key pressing state must be maintained. I'm checking to see if the other fingers I need to release. If there is a finger to release the key, this means that the finger is moving freely against the player's intention, and it will be an obstacle to playing, so that training is necessary. means.

  On the other hand, if it is determined in step S620 that the value of the pointer n exceeds 5, the value of the pointer a is incremented (step S621), and the incremented value of a is stored in a predetermined number, that is, the work RAM 3. It is determined whether or not the number of timer times T (a) is exceeded (step S622). If not exceeded, the process returns to S603, and the processes from S603 to S622 are repeated. That is, the above process is repeated by changing the timer time to another stored timer time. The timer time T (a) stored in the work RAM 3 is shorter as the value of a increases, and the key release timing instruction becomes shorter and faster. It is configured to increase.

  If it is determined that the value a exceeds the number of timer times T (a) stored in the work RAM 3, all the LEDs corresponding to the keys F (1) to F (5) are turned off (step S623). Inform the performer that this performance training has ended.

  Thereafter, the process proceeds to step S624 in FIG. 8, where 1 is set in the pointer a, and whether n, m data at this point exists in the AREA (a) of the work RAM 3 using the pointer a as an argument. Is determined (step S625). If no data exists, the value of a is incremented (step S626), and it is determined whether the value of a exceeds a predetermined number, that is, the number of AREA (a) stored in the work RAM 3 (step S626). S627) If not exceeded, the process returns to step S624 again.

Thus, if data exists in AREA (a), the data n and m are displayed on the display unit 5 (step S628).
This data shows a combination of two fingers that could not be released as intended with the slowest key release and the least difficult to perform, in other words, for the performer It becomes clearly recognizable that the manipulation of finger combinations is the weakest and requires training.

FIG. 12 is a diagram illustrating an example of display on the display unit 5.
In the figure, n = 1 and m = 3 are shown, and a thumb corresponding to n = 1 and a middle finger corresponding to m = 3 are identified and displayed. The arrow display indicates that the operation is in the order of thumb → middle finger.

Returning to FIG. 8 again, if it is determined in step S625 that there is no data in the area AREA (a), the display unit 5 displays that there is no data (step S629).
After these displays are made, it is determined whether or not a switch operation for resuming the process has been performed again by the SW unit 8 (step S630). If it is determined that the operation has been performed, the process returns to step S601 to resume the process. To do.
If it is determined that the resuming switch operation has not been performed, it is determined whether or not a mode change instruction has been issued (step S631). If there is a mode change instruction, a mode change process corresponding to the instruction is performed (step S632), and this process is exited. If there is no mode change instruction, the process returns to S630.

9 to 11 are subroutines of the music guide mode process (step S407) of FIG.
First, it is determined whether or not a music piece selection operation has been performed by the SW unit 8 (step S901). If it is determined that a song selection operation has been performed, the song number input by the SW unit 8 is stored in the register M (step S902).

  If it is determined that the music selection operation has not been performed, the process proceeds to step S903, where it is determined whether or not a music search operation has been performed. If it is determined that a search operation has been performed, 1 is first set to the pointer a (step S904). Next, it is determined whether or not the data n and m, that is, the number of the finger required for training exists in the AERA (a) of the work RAM 3 designated with a as an argument (step S905). If it is determined that it does not exist, a is incremented (step S906). Then, it is determined whether the value of a does not exceed a predetermined number, that is, the number of AREA () (step S907), and if not, the process returns to step S905.

  In this way, when it is determined that the data n and m, that is, the finger number required for training exists in AERA (a), the process proceeds to step S908, and this combination of finger numbers is now stored in AERA (a). Determine whether there are multiple. If it is determined here that there are a plurality, any one is selected in step S909, and if there are not a plurality, the process proceeds directly to step S910.

In step S910, the song having the largest number of combinations of finger numbers selected from AREA (a) is selected from the song data stored in the song data ROM 4.
Each event constituting the stored music data includes a finger number as shown in FIG. Therefore, it is determined whether the combination of the finger number included in each event and the finger number included in the subsequent event is the same as the combination of finger numbers selected from AREA (a). If the number of data in the data is counted, it is possible to search for music data having the largest number of combinations.
The music number of the music searched in this way is stored in the register M (step S911).

  On the other hand, if it is determined in step S903 that the music search operation has not been performed, or if the value of the pointer a exceeds a predetermined number in step S907, it is determined whether or not a mode change instruction has been given (step S912). . If there is a mode change instruction, a mode change process corresponding to the instruction is performed (step S913), and this process is exited. If there is no instruction to change the mode, the process returns to S901.

After the song number is stored in the register M in step S902 or S911, the process proceeds to step S914 in FIG. 10 and the initial values stored in the program ROM 2 in the areas F (1) to F (5) in the work RAM 3 Store finger position data.
Next, the LEDs of the LED group 7 corresponding to the keys having the key numbers stored in F (1) to F (5) in the work RAM 3 are turned on (step S915).

  Then, it is determined whether or not all the keys instructed by the lighting of the LED have been depressed (step S916). If it is determined that the performer has pressed all the fingers of the right hand and all of the instructed keys have been pressed, the process proceeds to step S917, and once F (1) to F ( The LED corresponding to the key having the key number stored in 5) is turned off. Further, the head address of the music data designated by the pole number M is set in the address pointer AD for reading the data of the music data ROM 5 (step S918).

  Subsequently, data representing 0 or 1 is randomly generated (step S919). Here, it is determined whether the randomly generated data is 0 (step S920). If it is 0, the LED of the key having the key number F (n) is turned on (step S921). After that, only the key of F (n) that the performer has pressed with the finger of the finger number n is once released and pressed again, and the key pressed with the other fingers. Determines whether the state is maintained (steps S922 and S923). If it is determined that this operation has been performed, the LED of the key having the key number F (n) is turned off (step S924). Otherwise, the processes in steps S922 and S923 are repeated.

  On the other hand, if the randomly generated data is 1, the LED of the key having the key number F (m) is turned on (step S925). After that, only the key of F (m) that the performer has pressed with the finger of the finger number m is once released and pressed again, and the key pressed with the other fingers. Determines whether the state is maintained (steps S926 and S927). If it is determined that this operation has been performed, the LED of the key having the key number F (m) is turned off (step S928). Otherwise, the processes in steps S926 and S927 are repeated.

In this way, if only the F (n) or F (m) key instructed by the lighting of the LED is released and pressed, and the other keys in the pressed state remain as they are, FIG. In step S929, the address pointer AD is advanced, and it is determined what the music data read from the music data ROM 5 by this AD is (step S930). If the read data is time, the process returns to step S929, and AD is advanced again. If it is an event, the process proceeds to step S931, the read event data is sent to the sound source 9, and the process returns to step S914.
On the other hand, if the read data is END indicating the end, this means that the reading of the music data has been completed, and the process returns to step S901 again.

Here, n and m are finger numbers that need to improve athletic ability, and F (n) and F (m) are keys to be pressed with fingers having n and m finger numbers. Each time the F (n) or F (m) is pressed as instructed, events included in the selected music data are sequentially read out and sounded.
In other words, training is performed by moving a finger that is determined to require athletic performance as instructed, and at the same time, using this poor finger, a song is played using a technique such as one-key play. Is called.

  As described above, in this embodiment, after all of a plurality of predetermined keys corresponding to each finger are pressed on the keyboard 6, at least one key is released and pressed at a designated timing. It is determined whether or not the key has been pressed, and in response to this, it is determined whether or not any of the other pressed keys has been released. If it is determined that the key has been released, the key that has been released and the instructed key are identified. After the key is specified, one of the specified keys is randomly specified at a predetermined timing while all the predetermined keys are pressed, and the specified key is released. Each time the key is pressed, the events are sequentially read out from the music data ROM 4 storing music data consisting of a series of events for instructing sound generation, and the read events are sent to the connected sound source 9.

  As a result, the performer can recognize which finger's athletic ability needs to be improved, and repeat this series of actions to improve the poor athletic ability of the finger. Furthermore, it is possible to give stimulation to the brain by repeating a series of actions such that one of the fingers holds the key pressed state and only the other fingers are released. It becomes possible to promote the activation of the brain.

Also, in this embodiment, in order to improve the motor ability of the finger that is determined to be poor at the operation, it is not possible to play a song prepared in advance as if performing a performance like a one-key play. Training to improve hand luck and other abilities is possible.
This makes it possible to perform training without special awareness of improving the ability of finger luck, etc., simply by playing a song, and the psychological burden on the performer is greatly reduced.

On the other hand, in this embodiment, it is a configuration that performs training only for the right finger, but it can also be applied to training for the left finger, and of course, it can also be applied to training for all fingers of both hands. It is.
Further, in the present embodiment, which finger is regarded as a poor player is detected, but of course, any finger may be selected. For this purpose, the player may arbitrarily set the finger numbers n and m detected in the training process.

  Furthermore, in the present embodiment, a combination of two types of fingers is selected, but naturally a combination of three types of fingers may be used.
