Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an automatic performance system, and more specifically, a self-performance piano and an electronic sound source are controlled by a controller. <Prior Art> Conventionally, this type of automatic performance system has , performance information including key codes generated based on piano key operations is stored in the controller, and later the controller supplies the stored performance information to the piano and selects the solenoids provided corresponding to each part. The electric field was excited to drive the piano's string-striking mechanism to generate musical tones.

<Problems to be solved by the invention> However, in the above-mentioned conventional automatic performance system,
Since the controller could only store performance information that corresponded to piano key operations, it was possible to automatically play the piano alone, but in order to perform an unsampled performance between the piano and other electronic sound sources, the player had to use other instruments. The problem was that the electronic sound source had to be operated separately, making it difficult to easily enjoy unsampled performances.

The present invention provides an unsampled performance between the piano and the electronic sound source, taking into account that if the controller stores not only the performance information of the piano but also the performance information of the electronic sound source, it is possible to perform an unsampled performance by simultaneously playing back the performance information. The purpose is to provide an automatic performance system that is easy to use.

<Means for Solving the Problems> The present invention provides a controller that stores performance information in a digital format and sequentially outputs the performance information, a mechanical sound generation mechanism that mechanically generates musical sounds based on key operations, and a mechanical sound generation mechanism that mechanically generates musical sounds based on key operations. An automatic performance system that includes a drive device that drives the mechanical musical sound generation mechanism based on performance information and an automatic performance piano that operates the mechanical sound generation mechanism based on performance information. Add more sound sources,
It is possible to store the performance information of multiple parts in the controller, and supply one of the performance information of the plurality of parts to the automatic performance piano, and the other performance information to the electronic sound source. The main points are as follows.

<Operations and Effects> In the automatic performance system having the above configuration, the controller stores the performance information of a plurality of pars 1~ in a digital format, and the performance information of one of the performance information of the plurality of pars 1~. is performance information regarding the automatic performance piano, and other performance information is performance information regarding the electronic sound source. The performance information of these multiple pars l~ is played back almost simultaneously and the performance information of these multiple pars l~
It is output from the roller and supplied to the player piano and electronic sound source.

Based on the performance information of one of the plurality of performance information outputted from the automatic performance piano controller 1~roller, the drive device is operated to drive the mechanical musical sound generation mechanism and mechanically generate the musical sound. . On the other hand, since electronic sound sources generate musical sounds electronically based on other performance information, unsampled performances between the player piano and the electronic sound source are automatically realized, and the piano can be played without any special operations on the electronic sound source. You can easily enjoy unsampled performances with electronic sound sources.

Furthermore, since the player piano has a mechanical tone generating mechanism, the player can play the piano himself while generating musical tones electronically using an electronic sound source.

<Example> An example of the present invention will be described below based on the drawings. 1st
The figure is a front view of one embodiment, and 1 is a controller building 1.
~Indicates a self-playing piano. This automatic performance piano 1 has a keyboard 3, a string-striking mechanism as a mechanical musical sound generating mechanism that performs string-striking, and a pedal mechanism based on a drive signal. The piano includes a group of solenoids (not shown) as a driving device for driving the piano, but the above-mentioned components are basically the same as those of a normal automatic performance piano, so a detailed explanation will be omitted.

An operation panel for a controller 7 is exposed on the upper front plate 5 of the automatic performance piano 1, and this controller 7 is equipped with an MID
The I output terminal is electrically connected via a cable 9 to the M I D I input terminal of the keyboard 1 as an electronic sound source.

Next, the operation panel of the controller 7 will be explained based on FIG. 2. The operation panel is provided with a power switch 13, and when this power switch]-3 is turned on,
A computer system built into the controller 7, which will be described later, is activated, and the power indicator is turned on.
5 is lit.

A floppy disk is inserted from the operation panel's disk tray]-7 and set in the disk driver.

On the other hand, to take out the floppy disk from the disk driver, the user only has to press the eject button 19. Reference numeral 21 denotes a song number display section, which constitutes a part of a file label of a file in which a series of performance information generated by a performance is stored at the time of recording. On the other hand, the liquid crystal display section 23 displays the title of the song, various setting values to be described later, the elapsed time during recording and playback, and the recording and playback levels.

The recording switch 25 is a switch that causes the controller 7 to wait for the start of recording, and functions in a playback mode when the recording switch 25 is not operated.

After the recording switch 25 is operated and the controller 7 enters a recording start standby state, when the start/pause switch 27 is operated, the performance by key operations can be recorded on a floppy disk. The start/pause switch 27 not only starts recording, but also temporarily stops recording or playback when operated after the start of recording or after the start of playback. The song selection/fast forward/reverse switch 29 is composed of a left button 31 and a right button 33, and this song selection/fast forward/reverse switch 29 is common to the song number selection mode and the fast forward/reverse mode during playback. used as That is, when the song selection/fast forward/reverse switch 29 is operated while waiting for recording to start or while recording is stopped, it cooperates with the song number display section 2 to enable selection of a file to be recorded or played back. On the other hand, when the song selection/fast-forward/fast-reverse switch 29 is operated during playback, the song being played is fast-forwarded or fast-backed.

The repeat switch group 35 is used to repeatedly play back a performance, and is used as an all-song switch 37 to repeatedly play back all the songs stored on the floppy disk that is loaded by the disk driver and to repeat only one specified song. A and -B switches 4 and 4 are used to repeatedly reproduce between any two points (between point A and point B) of a certain song.

The switch 43 is a switch for stopping operations such as recording, playback, fast forwarding, fast reversing, etc.

Subsequent volume switch 43, tempo switch 45, and transpose switch 47 are used together with increase button 49 and decrease button 51. That is, when the increase button 49 or the decrease button 51 is pressed after the volume switch 43 is operated, the already set volume value is changed, and after the tempo switch 45 is operated, the increase button 49 is pressed. Alternatively, when the decrease button 51 is pressed, the tempo of the song being played is changed by a predetermined percentage, for example, by 10%. On the other hand, when the increase button 49 or the decrease button 5 is pressed after the transposition switch 47 is operated, the pitch of the song is changed by a predetermined frequency during playback.

When playing an sample, the part cancel switch is
Used to change the part played on automatic piano 1,
It consists of an R button 53 and an L button 55. The R button 53 is used to increase the part number to be played on the automatic performance piano 1, and the L button 55 is used to decrease the part number.

The configuration of a computer system that controls recording or playback based on the operation of switches on the operation panel is as shown in FIG. Read and execute instructions sequentially. This ROM 75 contains the operating system and system initialization program, as well as the main program shown in Figure 4 and the main program shown in Figure 5 (A
) and (B) are also stored.

The working register 77 contains a code indicating the file name corresponding to the song number selected by the song selection/fast-forward/reverse switch 29, a data code related to repeated playback set by the repeat switch group 35, and a volume switch 4.
3 and a data code related to the volume value set by the increase and decrease switches 49.51, a data code related to the tempo set by the tempo switch 45 and the increase and decrease switches 49.51, and a data code related to the tempo set by the transposition switch 47 and the increase and decrease switches 49.51. Data codes related to pitches to be changed during playback set by , code data for parts to be played by automatic performance piano 1 during unsampled performance, etc. can be stored in respective predetermined registers.

The DMA controller 79 directly accesses the floppy disks stored in the floppy disk driver 81 via the common bus 73 under the control of the operating system, and in the playback mode, data is transferred from the working register 77 by the central processing unit 7. The performance information stored under the file name is sent from the MIDI input/output 83 to the automatic performance piano] and the electronic sound source 11. On the other hand, in the recording mode, encoded performance information generated based on key operations on the automatic performance piano 1 is written into a data storage area of a pre-specified file.

Here, a floppy disk on which performance information for a plurality of parts is encoded and written for unsampled performance will be described. Writing such multiple pieces of information can be done, for example, by M.
The encoded performance information of each part is assigned a different channel number and sequentially stored in the data storage area of the same file. In this way, performance information is MIDI
Since the message is stored as a message, it is possible to select the electronic sound source that constitutes the automatic performance system from a wide range of targets.

The switches 25 and the like provided on the operation panel of the controller 7 are connected to the central processing unit i! ? , 71, and when any switch 25, etc. is operated, the operated switch 25, etc. is determined by rough 1 to wear, and changes the program address or transfers the corresponding data code to the working register 77. be done.

Furthermore, data codes and the like set based on the operations of switches 25 and the like provided on the operation panel are periodically read out by the central processing unit 7 and displayed on the song number display section 21 and the liquid crystal display by the display controller 83. It is visually displayed in the section 23.

Next, the main program executed by the automatic performance system will be explained with reference to the flowchart shown in FIG. When the power switch 1-3 is turned on, the computer system executes the initialization program at step P.
1) Initialize the system. Next, the floppy disk driver 81 is scanned to select the floppy disk from Sera 1 to
It is determined whether or not (step P2). While the judgment in step P2 is NO, the floppy disk driver 8
1 continues, and waits for the determination in step P2 to be YES. If the determination in step P2 is YES, processing related to the floppy disk, such as checking whether formatting is necessary or not, and formatting the floppy disk if necessary, is performed (step P3). When step P3 is thus completed and writing to and reading from the floppy disk becomes possible, the switch group 25 and the like on the operation panel are scanned. That is, through this scanning, it is determined whether or not the music selection/fast-forward/fast-reverse switch 29 has been operated (step P4), and if the result of the determination is YES, the program proceeds to a reproduction subroutine program to be described later. On the other hand, if the judgment result in step P4 is NO, it is judged whether or not the recording switch 25 has been operated (step P5), and if the judgment result is YES, the process moves to the recording subroutine program and the player plays the piano. Coded performance information generated based on the key operation No. 1 is written into a data storage area of a pre-designated file. On the other hand, when the determination result in step P5 is NO, the floppy disk driver 81 is scanned again to determine whether or not the floppy disk has been ejected (step P5).
6). If the judgment result in step P6 is NO, step P
4 to P6 are repeated to wait for transition to the reproduction subroutine program or the recording subroutine program. On the other hand, if the determination result in step P6 is YES, the process returns to step P2 and waits until a new floppy disk is set and the determination result in step P2 becomes YES.

Next, the flow when the judgment result in step P4 is YES and the process moves to the reproduction subroutine program will be explained. 5(A) and 5(B) are subroutine programs for causing the automatic performance piano 1 and the electronic sound source 11 to perform an unsampled performance, and the floppy disk driver 8
1. When a floppy disk storing performance information of a plurality of parts encoded for unsampled performance is set in the floppy disk, and the music selection/fast forward/reverse switch 29 is operated, a music selection switch-on event occurs. Specifically, when the right button 33 is pressed, the song order advances, the song number displayed on the song number display section 2 increases, and the song title corresponding to the song number is displayed on the liquid crystal display section 23. On the other hand, when the left button 31 is pressed, the song order is returned and the song number displayed on the song number display section 2]- is decreased, and the song title corresponding to the song number is displayed on the liquid crystal display section 23. In this song selection subroutine R1, in addition to changing the display of the song number and song title, the name of the file in which the encoded performance information regarding the selected song stored in the register is written is also changed.
Prepare to start playing.

After this, 1, when the switch group 47 etc. are operated, the transposition subroutine R2, the repeat 1 to setting subroutine R3, the volume setting subroutine R4, and the tempo setting subroutine R5 are executed, respectively, and the number of degrees to be transposed when playing the automatic performance piano 1 is executed. The playback volume value, whether or not the unsampled performance is repeated, and the tempo of the automatic performance piano 1 and the electronic sound source 11 are respectively set. Of course, these subroutines will not be executed unless the switches R2, R3, R4, and R5 are operated, and the initialization program P]
Reproduction is performed using standard values set during one run.

Next, it is determined whether or not the song recorded on the set floppy disk has been recorded for unsampled performance (step P11), and if the determination result is no, processing is performed according to other playback modes. will be held. On the other hand, when the judgment result in step P11 is YES, it is judged whether or not the switches 1 to 43 have been operated (step P12), and while the judgment result is no, step P12 is repeated. Wait for the judgment result to be yes. Eventually, when the stop switch 43 is operated and the judgment result in step P12 becomes YES, the liquid crystal display section 2
3, a standard part to be played on the automatic performance piano 1, for example, the first part 1, is displayed (step P13). If you press the R button 53 or L button 55 to change the bar 1 to be played on the player piano 1, the judgment result in step P1.4 will be YES, and the part to be played on the player piano 1 will be changed. The number is changed, the code data of the newly set part is written into a predetermined register, and the part number of the bar 11 is displayed on the liquid crystal display section 23 (step P15).

In the following step, it is determined whether or not the star I~ pause switch 27 has been operated (step P16). If the judgment result in step PL'6 is no, step P14
Step P14 to Step P16 are then repeated to wait for the part to be played on the automatic performance piano 1 to be changed and the start and pause switch 27 to be operated. The start/pause switch 27 is operated and step P3-
If the judgment result in step 6 is YES, the coded performance information is sequentially read out from the file storing the performance information of the selected song title (step P17), and the tempo is adjusted to the preset tempo (step P18). . Next, it is determined whether the channel number attached to each encoded performance information matches the channel designated as the playback part of the automatic performance piano 1 (step P1
9). When the judgment result of step 19 is YES, the encoded performance information is sent to automatic performance piano 1 (
Step p20) After the code is converted in the automatic playing piano]-, the code is supplied to the drive device, and the corresponding solenoid is energized to drive the string-striking mechanism and the pedal mechanism. the result,
Automatic performance is performed based on the above music information.

On the other hand, if the judgment result in step 19 is NO, the encoded performance information is for bars 1~ to be reproduced by the electronic sound source 11, so it is transferred to the electronic sound source 11 and the encoded performance information is transferred to the electronic sound source 11. A musical tone is generated electronically (step 2]-). In the automatic performance system shown in FIG. 1, only one electronic sound source 11 is depicted, but M
JDI has ]-6 channels, so up to 15
You can connect multiple electronic sound sources.

When the unsampled performance between the player piano 1 and the electronic sound source is started, scanning of the switch group 25, etc. on the operation panel is started again, and it is determined whether or not the pause switch 27 for star 1 has been operated. (Step P22)
. If the judgment result in step P22 is YES, reading from the floppy disk is stopped (step P23).
When the restart/pause switch 27 is operated, it is determined whether or not to resume reading from the floppy disk (step P24). If the result of the determination is YES, the process immediately returns to step P17 and the reading from the floppy disk is resumed. Reading of performance information is resumed, but step P
If the judgment result in step 24 is no, the music selection subroutine R is performed again.
1, repeats the music selection subroutine R1 to step P16 and waits for resumption of performance information reading.

On the other hand, if the judgment result in step P22 is NO, the switch group 2 on the operation panel continues reading out the performance information.
Scan 5th grade. That is, when the song selection/fast forward/reverse switch 31. In this case, it is determined whether or not the tempo switch 45 has been operated (step P27). If the judgment result in step P27 is YES, change the tempo during playback in step P
28), Step P If the judgment result in 27 is NO, it is judged whether or not the transposition switch 47 has been operated (Step P
29). If the judgment result in step P29 is YES, the part being played back on the automatic performance piano 1 is transposed (step P30). On the other hand, if the determination result in step P29 is NO, it is determined whether or not Libby 1 to switch group 35 has been operated (step P31). If the determination result in step P31 is YES, the repeat corresponding to the pressed switches 37 to 41 is performed. If the determination result in step P31 is NO, it is determined whether the volume switch 43 has been operated (step P33). If the determination result in step P33 is YES, the player is playing on the player piano 1. If the determination result in step P33 is NO, it is determined whether or not the stop switch 43 has been operated (step P35).
). If the determination result in step P35 is YES, the process returns to the main flow described in FIG. 4, and if the determination result in step P35 is NO, it is determined whether reading from the floppy disk has been completed (step P36). If the judgment result in step P36 is YES, stop switch 4
The process returns to the main flow in the same way as when 3 was operated, and if the determination result in step P36 is NO, the process returns to step P17 to continue reading performance information from the floppy disk. Therefore, in this embodiment, the volume etc. of the automatic performance piano 1 can be changed even during playback, and an unsampled performance that is in harmony with the electronic sound source 11 can be performed.

Further, in the above embodiment, the automatic performance system is configured using an upright automatic performance piano, but a grand piano capable of automatic performance may also be used. Further, in the above embodiment, the controller is incorporated into the automatic performance piano, but the controller may be installed independently from the automatic performance piano.
