Description

  The present invention relates to an ensemble system capable of performing an ensemble with a simple performance operation.

There has been proposed an electronic musical instrument that can be easily performed even by people who are unfamiliar with the operation of the musical instrument (Patent Document 1). According to the proposed electronic musical instrument, it is possible to perform an ensemble with a simple operation such as waving.
When people who are unfamiliar with the operation of the instrument perform an ensemble for rehabilitation, etc., a group is formed with a predetermined number of people (for example, about 5 people), and a facilitator (guide role, ensemble leader) is a participant Often leads (students) to perform ensembles.
Therefore, the present inventors have proposed an ensemble system in which performance parts can be easily and flexibly allocated between the facilitator and each participant (Japanese Patent Application No. 2005-281060).
JP 2000-276136 A

According to the above-described ensemble system proposed by the present inventors, performance parts can be easily and flexibly allocated between the facilitator and the ensemble participants (students). In the case of increasing / decreasing for each concert, the facilitator needs to manually change the attendance setting for each performance terminal, which is troublesome.
In addition, due to setting mistakes and omissions, there were cases where the ensemble could not be started successfully.

The present invention aims to ensemble participant (student) is by a trial and beating before the start if so, to determine automatically attendance / absence, provides an ensemble system capable of setting It is said.

In order to achieve the above object, an ensemble system according to the present invention includes a plurality of pads for detecting a player's operation , and connected to the plurality of pads, and the operation is detected by a player's operation on each pad. A trigger module that outputs performance data including pad identification information for identifying a pad, and a control device that controls the generation of musical sounds by reading performance information from music data based on the performance data output from the trigger module An ensemble system comprising: before the start of the ensemble, participating in the ensemble based on pad identification information included in performance data output from the trigger module by a trial hitting operation by a participant in the ensemble the identifying pad, means for determining attendance to the ensemble of the pad, play is determined that attend pad par to Means for assigning, and based on performance data output from the trigger module, operation of the player is having a means for generating a tone performance parts allocated to the sense pads.
Furthermore, the means for determining the presence / absence of the performance data further includes a reception timing of performance data output from the trigger module by the trial hitting operation with a unique rhythm pattern by a participant of the ensemble before the start of the ensemble. detects, by comparing the specific rhythm pattern registered is assumed to have a function of identifying a participant individual to the ensemble.

According to the ensemble system of the present invention, by making the attempt to strike the pad to be handled participants of their own, because there is automatically attendance / absence of the setting of the ensemble is made, it must be the facilitator to perform manually configure This eliminates troublesome work.
In addition, since the attendance setting is automatically performed, an artificial setting error can be prevented.
Furthermore, according to the present invention having the function of specifying individual participants, it is possible to maintain the correspondence between the participants and the performance parts regardless of which performance terminal the ensemble participant selects.

FIG. 1 is a block diagram showing the configuration of the first embodiment of the ensemble system of the present invention. As shown in this figure, this ensemble system includes a controller 1 and a plurality of (six in the example of FIG. 1) performance terminals 2A to 2F connected to the controller 1 via a MIDI interface box 3. .
The controller 1 controls the entire ensemble system based on a control program, and is composed of, for example, a personal computer.
The performance terminals 2A to 2F are those in which facilitators and participants (students) perform performance operations and generate musical sounds according to the performance operations, and are MIDI-compatible electronic keyboard instruments such as an electronic piano. Each of the performance terminals 2A to 2F is connected to a plurality of MIDI ports provided in the MIDI interface box 3, and is connected to the controller 1 via the MIDI interface box 3. Each performance terminal 2A to 2F is identified by the port number to which the MIDI interface box 3 is connected.
In the example of this figure, for example, the performance terminal 2A connected to the MIDI port 0 is used as a performance terminal for a facilitator (ensemble reader), and the performance terminals 2B to 2F connected to the MIDI ports 1 to 6 are used for students. As a performance terminal. Such a terminal designation is performed by the controller 1.
The performance terminal is not limited to the electronic piano, but may be another form of electronic musical instrument such as an electronic guitar. Of course, in terms of appearance, the terminal is not limited to a natural musical instrument, and may simply be a terminal provided with an operator such as a button.

FIG. 2 is a block diagram showing the configuration of the controller 1. As shown in this figure, the controller 1 operates as a communication unit 11 connected to the MIDI interface box 3, a control unit 12 that controls the controller 1, an HDD 13 that stores control programs and music data, a work memory, and the like. A RAM 14, an operation unit 15 such as a keyboard and a mouse, and a display unit 16 for displaying various information are provided.
The control unit 12 reads out a control program stored in the HDD 13 and develops it in the RAM 14 as a work memory, and executes processes such as an attendance setting process 31, a part assignment process 32, a sequence process 33, and a display process 34. The part assignment process 31 is a process for assigning each performance part of music data to a plurality of performance terminals 2. The sequence processing 32 is a sound source such as sound generation instruction data or mute instruction data for generating a musical tone in the performance part assigned to the performance terminal of the music data in accordance with the note-on message or note-off message received from each performance terminal 2. In this process, control data is generated and transmitted to a sound source built in the performance terminal 2 at a timing at which the musical sound should be generated. The display process 33 is a process for displaying various information for performing an ensemble on the display unit 16.
The operation unit 15 is mainly used by the facilitator to instruct the operation of the ensemble system. The facilitator operates the operation unit 15 to specify, for example, music data of a song to be played, or to assign a performance part of each performance terminal 2.
The display unit 16 is a so-called display (monitor), and the facilitator and each user perform a performance operation while watching the display unit 16. A large external display can be used as the display unit 16 so that everyone can easily see the display contents.

FIG. 3 is a block diagram showing a configuration of the performance terminal 2. In this embodiment, the performance terminal 2 is a MIDI-compatible electronic keyboard instrument, and includes a communication unit 21, a control unit 22, a keyboard 23 as a performance operator, a sound source 24, and a speaker 25, as shown in this figure. Yes. A communication unit 21, a keyboard 23, and a sound source 24 are connected to the control unit 22, and a speaker 25 is connected to the sound source 24.
The communication unit 21 is a MIDI interface circuit and communicates with the controller 1 via the MIDI interface box 3.
The control unit 22 is a control unit that controls the performance terminal 2 in an integrated manner.
The keyboard 23 has, for example, 61 keys and 88 keys, and is capable of playing in a 5-7 octave range. In this ensemble system, on / off and keystrokes are made without distinguishing individual keys. Only strength data is used. That is, each key has a built-in sensor for detecting on / off and a sensor for detecting the strength of the keystroke, and the keyboard 23 controls the operation mode of each key (which key is pressed with what strength, etc.). ) Is output to the control unit 22. The control unit 22 creates performance data of the performance terminal 2 based on the input operation signal, and transmits the performance data to the controller 1 via the communication unit 21. Specifically, a note-on message is created and transmitted when the keyboard is pressed, and a note-off message is created and transmitted when the keyboard is released.
When the performance terminal 2 is turned on, active sensing, which is a MIDI system real-time message, is periodically output.
The sound source 24 generates a musical sound waveform according to sound source control data supplied from the controller 1 via the control unit 22, and the generated musical sound signal is emitted from the speaker 25.
Note that the sound source and the speaker need not be built in the performance terminal 2. A sound source and a speaker may be connected to the controller 1 so that a musical sound is generated from a place different from the performance terminal 2. Although the same number of sound sources as the performance terminals 2 may be connected to the controller 1, a single sound source may be used.

FIG. 4 is a diagram showing an example of music data stored in the HDD 13 of the controller 1. The music data is sequence data such as SMF (Standard MIDI File).
As shown in this figure, the music data is composed of a plurality of performance parts, and includes identification information for identifying each performance part and performance information (sequence data) of each performance part. The performance information includes a combination of time information (delta time) representing a time interval between events and event information (MIDI event or the like) in the order of event occurrence.

In the ensemble system configured as described above, when the ensemble participants (students) turn on the performance terminals 2B to 2F used by themselves, the attendance status is automatically determined by the controller 1 and determined to be attended. One or a plurality of performance parts of music data to be played are assigned to the played performance terminals.
Here, in this ensemble system, the number of times the student should play the keyboard (number of beats) in one measure is set beforehand. For example, in a 4/4 time tune, the number of beats is 2 Is set so that the student plays the key every other beat, and the musical sound for two beats is generated by one key hit.
When a ensemble participant performs a performance operation (for example, keying an electronic piano keyboard) using the performance terminal 2 assigned to him, a note-on message or a note-off message corresponding to the controller 1 is transmitted. The controller 1 generates sound generation instruction data and mute instruction data for the number of beats set in the performance part assigned to the performance terminal 2 based on the input note-on / note-off message, and the performance terminal 2 to send. The performance terminal 2 generates a corresponding musical sound based on the sound generation instruction data and the mute instruction data sent from the controller 1. For example, as described above, when the number of beats is 2 in 4/4 time, the first and second beats are generated by the first keystroke in the measure, and the third and fourth beats are generated by the next keystroke. A beat sound is generated.
As a result, each user (student) can perform with a simple operation of pressing the keyboard with one finger, and each user (student) can enjoy with multiple people by taking the tempo according to the facilitator. While performing an ensemble.

The flow of such ensemble processing will be described with reference to the flowchart of FIG.
Before performing the concert, first, the performance terminals 2A to 2F and the controller 1 are turned on to start the control program (step S1). That is, the person (student) participating in the ensemble turns on the performance terminals 2B to 2F used by each person, and the facilitator turns on the performance terminal 2A and the controller 1 used by the facilitator and activates the control program. To do.
When the control program is activated, an attendance setting process is executed by the control unit 12 (step S2). In this embodiment, the performance terminals 2A to 2F are MIDI electronic keyboard instruments that support active sensing. When the power is turned on, the performance terminals that are turned on receive active sensing (MIDI system real-time messages). FEH) is automatically transmitted from the MIDI OUT terminal.
Therefore, in this attendance setting process, a MIDI port to which active sensing is transmitted is detected, and a student of a performance terminal corresponding to the MIDI port attends and a student of a performance terminal corresponding to a MIDI port to which active sensing is not transmitted. Is determined to be absent, and the situation is stored in the RAM 14.
In this embodiment, the presence / absence of the performers of the performance terminals 2A to 2F is determined by using active sensing as information indicating the operation state of the performance terminals. Any signal can be used as the operating state information of the performance terminal as long as it is a signal notifying that it is turned on.
Thus, according to the present invention, it is possible to automatically determine and set the student's attendance state.

Next, the facilitator selects a performance tune to perform ensemble (step S3). This processing is performed by selecting a song to be played using the operation unit 15 from among the song data displayed on the display unit 16 of the controller 1.
When a performance piece is selected, the control unit 12 executes part assignment processing for assigning the performance parts of the performance piece to a plurality of performance terminals 2 connected thereto. For example, the control unit 12 performs a process of sequentially assigning the performance parts of the performance pieces to the performance terminals of the attendees one by one, and changes the part assignment set by the control unit 12 when a facilitator is necessary. .

FIG. 6 is a diagram illustrating an example of part assignment.
In the example shown in this figure, participant 4 is absent and the other participants (1-3 and 5) are present. In the case where the selected performance music is a 9-part music indicated by part numbers 1 to 9, as shown in the figure, the attending participants are assigned to all the participants fairly. In contrast, one part is assigned at a time. As for the facilitator, the facilitator itself assigns parts separately.
After the part assignment is performed by the control unit 12 in this way, the facilitator can arbitrarily change the assignment.

When the operation for instructing the start of the ensemble is performed after the part assignment process (S4) is completed in this way, the performance process (S6) is started.
The details of the performance processing will be described later, and is processing for generating a musical sound corresponding to the performance input in response to performance input from the performance terminals 2A to 2F. It consists of a sequence process executed by the control unit 12 in response to a MIDI message sent from the performance terminal. When a participant performs a simple performance operation such as pressing a single key using the performance terminals 2B to 2F, a note-on message and a note-off message are transmitted from the performance terminal to the controller 1. In the controller 1, in accordance with the note-on / note-off message input from the performance terminal, the sound generation instruction data for the note to be generated is generated according to the keystroke of the performance part assigned to the performance terminal by the sequence processing. It transmits to the performance terminal 2. Thereby, the corresponding musical sound is generated from the sound source of the performance terminal 2 and an ensemble is performed.

After the ensemble of the music selected in the performance process S6 is completed, the facilitator determines whether or not to end the ensemble (S7). It is determined whether there are students who do not participate in the concert (S8). When there is a student who does not participate in the next ensemble, a process of setting absence for the student is performed (S9). This process is automatically performed by the control unit 12 of the controller 1 when a student who does not participate in the ensemble turns off the performance terminal 2, but the facilitator manually sets it using the operation unit 15. You can also.
Then, the process proceeds to the performance music selection process in step S3, and the next music to be played is selected. Thereafter, the same processing as described above is performed.

Details of the performance processing (S6) will be described with reference to FIGS.
FIG. 7 is a flowchart showing a flow of processing executed when the keyboard 23 is operated in the performance terminal 2.
When the user presses the keyboard 23 of the performance terminal 2 with a finger (step S11), the operation signal is sent from the keyboard 23 to the control unit 22, and the control unit 22 transmits a note-on message to the controller 1 (step S12). . As described above, this note-on message includes velocity information indicating the strength of keystroke.
When the user returns the keyboard 23 to the original state (releases his / her finger) (step S13), the operation signal is sent from the keyboard 23 to the control unit 22, and the control unit 22 transmits a note-off message to the controller 1 ( Step S14).

FIG. 8 is a flowchart showing a flow of sequence processing executed in the controller 1 when a note-on / note-off message is received from the performance terminal 2.
When the controller 1 receives a note-on message or a note-off message from the performance terminal 2 (step S21), the controller 1 indicates the type (note-on or note-off) and content (velocity information) of the received message and its reception timing (time). Each performance terminal is stored in the RAM 14 (step S22). As will be described later, the performance parameters (tempo, rhythm, dynamics, etc.) of each performance terminal 2 can be acquired using this information.
If the received message is a note-on message (YES in step S23), the length to be sounded by the keystroke from the performance information of the performance part assigned to the performance terminal 2 that transmitted the message. Minute performance information is read (step S24). For example, as described above, when the number of beats is 4/4 and the number of beats is 2, performance information for two beats is read, and when the number of beats is 4, performance information for one beat is read (step S24).
Then, sound generation instruction data for generating sound corresponding to the performance information of the first beat is generated and transmitted to the performance terminal 2 (step S25), and the next message is waited for.
The sound generation instruction data is supplied to the sound source 24 by the control unit 22 of the performance terminal 2, and the corresponding musical sound is emitted from the speaker 25.

When the message received from the performance terminal 2 is a note-off message (NO in step S23), the controller 12 of the controller 1 generates corresponding mute instruction data and transmits it to the performance terminal (step S26). ). As a result, the generation of the musical sound produced in step S25 in response to the note-on message is stopped.
Next, the elapsed time from the reception of the preceding note-on message to the reception of the note-off message is measured using the information stored in step S22 (step S27), and the measured elapsed time is used. The tempo of performance by the user of the performance terminal is calculated and set (step S28).
Next, it is determined whether or not there is performance information to be subsequently generated in the performance information read in step S24 (step S29). When the result of the determination is YES, the sound generation instruction data and the mute instruction data corresponding to the performance information to be sounded are created and transmitted to the performance terminal 2 (step S3). That is, the delta time of the performance information to be sounded is counted using the tempo calculated in step S28, and the sound generation instruction data corresponding to the performance information is transmitted to the performance terminal 2 when the sound generation timing comes. . At this time, the velocity information included in the sound generation instruction data is also a value corresponding to the strength of the user's keystroke, as described above. Then, when the sound length has elapsed, the corresponding mute instruction data is transmitted to the performance terminal 2. Such processing is repeated, and sound source control data such as sound generation instruction data and mute instruction data is transmitted to the corresponding performance terminal 2 for all performance information to be sounded by the keystroke, and then the process returns to the step S21 and the next note Wait for receipt of on message.
In this way, each time the user presses the keyboard once, the above process is repeated, and according to the keystroke of the keyboard, the performance information having a length corresponding to the number of beats set is played. It can be performed at a volume corresponding to the strength and a tempo corresponding to the keystroke.

Next, a second embodiment of the ensemble system of the present invention will be described.
In this embodiment, a ensemble participant (student) uses a drum pad (pad) of an electronic percussion instrument as a performance terminal. Each student takes charge of one pad and performs an ensemble by hitting the pad.
FIG. 9 is a block diagram showing the configuration of the second embodiment of the ensemble system of the present invention. In this figure, the same components as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.
In FIG. 9, 2G, 2H,..., 2M, 2N are drum pads, which are used by the students 1 to 8 as performance terminals, respectively.
Reference numeral 4 denotes an electronic percussion instrument trigger module. The trigger module 4 is configured so that a plurality of (for example, nine) drum pads can be connected. When Each pad is attached a sensor for detecting vibration, the pad is struck by the output of the sensor exceeds a predetermined threshold, the trigger module 4, note number corresponding to the path head A note-on message having a velocity corresponding to the output of the sensor is sent to the controller 1 via the MIDI interface box 3.
Reference numeral 5 denotes a sound source connected to the controller 1, and reference numeral 6 denotes a speaker that emits musical sounds generated by the sound source. Usually, the electronic percussion instrument trigger module 4 has a built-in sound source, and the built-in sound source may be used as the sound source 5. Further, a sound source 5 may be provided for each student so that musical sounds based on the performance of each student may be output independently.

In the embodiment configured as described above, the ensemble is executed according to the flowchart shown in FIG. However, the method for confirming the student attendance status in the attendance setting process in step S2 is different from that in the first embodiment.
That is, in the first embodiment described above, the power-on state of each performance device, that is, the student's attendance state is recognized based on the presence or absence of active sensing periodically transmitted from the MIDI device. However, in this second embodiment, the electronic percussion instrument trigger module 4 itself is a single MIDI instrument, and when the power is turned on, active sensing is transmitted to the controller 1. The individual attendance status of the students using the drum pads 2G to 2N cannot be known.
Therefore, in this embodiment, before the start of the ensemble, each student hits each drum pad, so that the player is hit by the note number included in the note-on message sent from the trigger module 4. The pad is identified, and the attendance status of participants in the ensemble is determined and set based on the specified pad. Trial hitting a pad before actually starting an ensemble is a common practice, and this trial hit is used for attendance determination.
That is, in the attendance setting process in step S2 in FIG. 5, when the note-on message is input from the MIDI port corresponding to the trigger module 4, the controller 12 of the controller 1 records the note number, The student of the pad corresponding to the note number to which the on message is sent is present, and the student of the pad corresponding to the note number not included in the note on message is determined to be absent.
In this embodiment, the note number is used as the performance terminal identification information for identifying each of the drum pads 2G to 2N. However, the present embodiment is not limited to the note number, and the drum pad that outputs the performance data is used. Any information that can be identified can be used as performance terminal identification information.
In this way, the presence / absence state is set and the process proceeds to step S3 and subsequent steps.

10A and 10B are diagrams showing an example of the display screen of the display unit 16 of the controller 1, where FIG. 10A shows a state in which everyone is absent, and FIG. 10B shows a state after the student 1 has hit his / her pad. Yes.
In the example shown in this figure, the display screen 51 includes a song title display area 52, a song time signature and total bar number display area 53, a performance song selection area 54, a play button 55 for instructing performance start, and a performance stop. A stop button 56 for instructing, an attendance state for the ensemble, and an area 57 for displaying part assignment are provided.
As shown in the drawing, in the area 57 for displaying the attendance status and part assignment to the ensemble, buttons corresponding to the ensemble participants (facilitators and P1 to P8 corresponding to students 1 to 8) are arranged. On the right side of each button, there is provided an area (BAR) for displaying a measure being played by the participant and an area (PART) for displaying a part assigned to the participant. The button displays attendance information of participants, and in the case of attendance, the display mode is different from the button of absentees (for example, a different display color).
In the initial state immediately after step S1 in FIG. 5 is executed, all of the students 1 (P1) to 8 (P8) are absent as shown in FIG.

It is assumed that student 1 (P1) hits the pad (2G) during the attendance setting process in step S2. Thus, a note-on message having a note number corresponding to the pad and a velocity corresponding to the strength is sent from the electronic percussion instrument trigger module 4 to the controller 1. The controller 12 of the controller 1 analyzes the note-on message, determines that the pad (2G) has been hit from the note number included therein, and uses the pad (2G). It is determined that the student 1 (P1) is present and is stored in the RAM 14. As a result, as shown in FIG. 10B, the display of the student 1 (P1) is in a display form that can be distinguished from others (indicated by hatching in the figure). After that, a performance part is assigned to student 1 (P1) who has been attended.
Similarly, when another student (for example, P2) hits the pad, it is determined that the student 2 using the pad is present, and the display form of the button (P2) of the student 2 is changed. Then, performance parts are assigned to the students 1 and 2 in the same manner as described with reference to FIG.

Note that when the pad corresponding to each student is hit, the student enters the attendance state, but this function is disabled during the performance process (S6). On the display screen, the performer cannot be put into attendance using the mouse or keyboard of the operation unit 15.
On the other hand, in the case of absence from attendance (step S9), the student is designated by pressing “1” to “8” on the keyboard or clicking the buttons “P1” to “P8” with the mouse. Can be absent. However, once you are absent, you cannot attend unless you strike the pad again.

After performing the attendance setting process (S2) in this way, step S3 and subsequent steps in FIG. 5 are executed to perform an ensemble.
When a drum pad is used as a student performance terminal, the performance process (S6) is performed as shown in FIG.
That is, when the student strikes the drum pad, the detection signal of the vibration sensor provided on the drum pad is input to the electronic percussion instrument trigger module 4. When receiving the output signal from the connected drum pad (S41), the electronic percussion instrument trigger module 4 generates a note-on message having a note number corresponding to the pad and a velocity corresponding to the magnitude of the output signal. To the controller 1 (S42). Note that a note-off message is not output from the electronic percussion instrument trigger module 4.
When receiving the note-on message from the electronic percussion instrument trigger module 4 (S51), the controller 12 of the controller 1 specifies a pad based on the note number included in the note-on message, and the note-on message for each pad. Is received (S52). Then, the performance information corresponding to the predetermined beat number of the performance part assigned to the pad is read (S53), and the sound generation instruction data corresponding to the performance information of the first beat is transmitted to the sound source (S54). Next, the tempo is calculated for each performance part from the reception timing of the note-on message received from the pad (S55). Note that the initial value of the tempo is the tempo recorded in the song data. Then, mute instruction data corresponding to the sound generation instruction data transmitted in S54 is transmitted to the sound source at a timing according to the tempo of the part (S56).
Next, it is determined whether or not there is performance information for the subsequent beat to be pronounced in response to the note-on message for that part (S57). The corresponding sound generation instruction data and mute instruction data are transmitted to the sound source at the timing specified by the performance information.
Then, the process returns to S52 and waits for reception of the next note-on message.
When the facilitator uses an electronic keyboard instrument as the performance terminal 2A, the processing corresponding to the performance data from the performance terminal 2A is the same as that shown in FIG.

Next, a third embodiment of the present invention will be described.
In the first and second embodiments described above, attendance / absence is determined and set in units of performance terminals used by the participants. In the third embodiment, performance terminals are used. Instead, attendance / absence can be determined for each individual.
Here, as in the second embodiment, a drum pad is used as a performance terminal for each student.
In this embodiment, each student determines his own rhythm pattern (the number of times the pad is hit and the timing of hitting the pad), hits the pad with that pattern in advance, and inputs the note-on message to the controller 1. Then, it is stored in the RAM 14 or the HDD 13. Then, in the attendance setting process in step S2 of FIG. 5, the drum pad used by the user is trial-tested with the own rhythm pattern. For example, personal patterns such as “Tan Tang” for Mr. A, “Tata Tang” for B, “Tata Tata Tan” for C, etc. are registered in advance. Hit the pad with a unique pattern.
The control unit 12 of the controller 1 receives the note-on message transmitted from the electronic percussion instrument trigger module 4, identifies the pad participating in the ensemble by the note number included in the message, and further, the same note The reception timing of the note-on message having the number is detected, and compared with the registered rhythm pattern, the name of the student who uses the pad is identified.
As described above, by identifying the student and determining the attendance, if there is a correspondence between the student and the performance part, the performance part can be assigned without breaking it. Regardless of the position at which the student sits and selects which performance terminal, the desired performance part can be assigned to the student.

In the above description, the performance terminal used by the student is a drum pad. However, as in the first embodiment described above, an electronic keyboard instrument may be used. In this case, each student plays a rhythm pattern or melody unique to the student, and the note-on / note-off message is registered in the controller 1 in advance, and the pattern or You can play the melody by playing it. The controller 12 of the controller 1 can identify the performance terminal participating in the ensemble by the port number to which the active sensing is sent, and the note-on message and the note-off message received via the port. The student using each performance terminal can be identified by comparing the timing and note number with the rhythm pattern and melody unique to each registered student.
Thus, by using a rhythm pattern or melody unique to a player as player identification information for identifying the player, the attendance can be determined for each student.
This makes it possible to assign a desired performance part to the same student as described above.
