Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic performance system, and more particularly to an automatic performance system in which a self-playing piano is controlled by a controller to generate at least mechanical musical sounds.

<Prior art> Conventionally, this type of automatic performance system stores performance information including key codes generated based on piano key operations in a controller, and later supplies the performance information stored by the controller to the piano. Then, solenoids provided for each part were selectively excited to drive the piano's string-striking mechanism and generate musical tones. However, in the conventional automatic performance system described above, the controller could only store performance information corresponding to piano key operations, so although it was possible to automatically perform the piano independently, In order to perform an unsampled performance, the performer must operate another electronic sound source, which poses a problem in that the player cannot easily enjoy unsampled performances. Therefore, in Patent Application (1) dated March 29, 1985, the applicant stores performance information of multiple parts in the controller, and among the performance information of the multiple parts,
We have proposed an automatic performance system that can automatically perform unsampled performances by supplying the performance information of - to the automatic performance piano and other performance information to the electronic sound source.

<Problems to be Solved by the Invention> The automatic performance system described above has made it easy to enjoy unsampled performances, but if the controller stores performance information for multiple songs, the song to be played may not be visible. The present invention was made based on the above-mentioned request, and an object of the present invention is to provide an automatic performance system that can visually display symbols related to a piece of music when selecting a piece of music.

Means for Solving the Problems> The present invention provides a controller that has a storage section that stores performance information in a digital format and sequentially outputs the performance information, a keyboard that is composed of a plurality of keys, and a controller for the keyboard. a mechanical sound generation mechanism that mechanically generates a musical sound based on N operation;
performance information forming means for forming performance information based on the key operation in a recording mode and transmitting the performance information to the storage unit;
The automatic performance system includes an automatic performance piano having a drive device that drives the mechanical tone generation mechanism based on performance information supplied from a storage unit, and the controller is configured to change the mode of the keyboard to a symbol input mode. means, a symbol code generating means for generating a symbol code of a symbol corresponding to a key operated in the symbol input mode, a code sending means for storing the symbol code in the storage unit in association with the performance information; The present invention further includes display means for reading the symbol code from the storage unit and visually displaying the symbol based on the symbol code.

<Action and effect> ” Regarding the automatic performance system related to the composition of Yuki.

As shown in the frame correspondence diagram of FIG. 1, in the recording mode, the performance information forming means 3 is based on key operations on the keyboard 1.
forms digital performance information corresponding to the operated key. This performance information is stored in the storage section 5 of the controller, read out during playback, and read out when playing the drive unit V! 17, and the drive unit [7 drives the mechanical tone generating mechanism 9 based on the performance information to mechanically generate musical tones. In order to visually identify the performance information stored in the storage unit 5 during the recording mode from the performance information already stored in the storage unit 5 or other performance information to be stored thereafter, a symbol code is added to the performance information. To add a symbol code, the mode changing means switches the keyboard to the symbol input mode, and the symbol code generating means 1
3, a symbol code corresponding to the operated key is generated. The symbol code thus generated is sent from the code sending means 15 to the storage section 5 in correspondence with the series of performance information, and is stored in the storage section 5 in association with the performance information. In this way, the symbol code is stored in association with the performance information, so when the symbol code is displayed on the display means 17 based on the symbol code, the performer etc. can easily select music based on the symbol.

<Example> An example of the present invention will be described below based on the drawings. Second
The figure is a front view of one embodiment, and numeral 21 indicates a self-playing piano with a built-in controller. The automatic performance piano 21 includes a keyboard 23 and a string-striking mechanism as a mechanical musical sound generating mechanism that strikes strings based on key operations of the various parts constituting the keyboard 23.

It has a soft pedal 25 for operating the pedal mechanism, a loud pedal 27, and a group of solenoids (not shown) as a drive device that drives the string-striking mechanism and the pedal mechanism based on a drive signal. The above-mentioned string-striking mechanism and the like are basically the same as those of a normal automatic performance piano, so a detailed explanation will be omitted. Further, in the song title input mode as the symbol input mode, the soft pedal 25 and the loud pedal 27 are used as a character mode change pedal and a character input pedal, as will be described in detail later. Key operations on the keyboard 23 are detected by a key switch circuit, and pedal operations on the soft pedal 25 and loud pedal 27 are also detected by switches provided corresponding to these pedals 25 and 27.

A controller 31 is mounted on the upper front plate 29 of the automatic performance piano 21.
The operation panel of the controller 31 is exposed.
has a MIDI output terminal (not shown), so you can connect it to an electronic sound source, such as a keyboard, etc. via a cable.
It can be electrically connected to the input terminal.

Next, the operation panel of the controller 31 will be explained based on FIG. 3. The operation panel is provided with a power switch 33, and when this power switch 33 is turned on,
A computer system built into the controller 31, which will be described later, is activated, and the power indicator 3 is turned on.
5 is lit. A floppy disk is inserted into the disk tray 37 of the operation panel and set in the disk driver. On the other hand, to take out the floppy disk from the disk driver, the eject button 39 can be pressed. 41 is a song number display section.

The data code of this song number constitutes a part of the file label of the file area that stores a series of performance information generated by the performance. On the other hand, the liquid crystal display section 43 displays the song title corresponding to the song number, various setting values to be described later, the elapsed time during recording and playback, and the recording and playback level.

The recording switch 45 is a switch that puts the controller 31 into a recording start standby state in the recording mode, and also serves as a changeover switch from the recording mode to the symbol input mode.

On the other hand, if other switches are operated without operating the recording switch 45, the device functions in the playback mode.

After the recording switch 45 is operated and the controller 31 enters a recording start waiting state, when the start/pause switch 47 is operated, the performance by key operations can be recorded on a floppy disk.

The start/pause switch 47 not only functions to start recording, but also functions as a stop switch that temporarily stops recording or playback when operated after recording or playback has started.1 Song selection/fast forward/reverse switch 49 is located on the left. Button 5
1 and a right button 53, and this song selection/fast forward/reverse switch 49 is commonly used in the song number selection mode and the fast forward/reverse mode during playback. That is, when the song selection/fast-forward/fast-reverse switch 49 is operated when inputting a song title, etc., while waiting to start recording, or while stopped, it cooperates with the song number display section 41 to input the song name, etc., and select the file to be recorded or played. allows for selection. On the other hand, when the song selection/fast-forward/fast-reverse switch 49 is operated during playback, it fast-forwards or fast-reverses the song being played.6 The repeat switch group 55 is used to repeatedly play the performance, and An all-song switch 57 that repeatedly plays all the songs stored on the floppy disk set in the driver, and a one-song switch 59 that repeatedly plays only one specified song. and an A-B switch 61 that repeatedly reproduces the data (between the two points). stop switch 63
is a switch for stopping operations such as recording, playback, fast forward, fast rewind, etc.

Subsequently, a volume switch 65, a tempo switch 67, and a transposition switch 69 are used together with an increase button 71 and a decrease button 73. That is, when the increase button 71 or the decrease button 73 is pressed after the volume switch 65 is operated, the already set volume value is changed, and after the tempo switch 67 is operated, the increase button 71 or the decrease button 73 is pressed. When is pressed, the tempo of the song being played is changed by a predetermined percentage, for example 10%. On the contrary,
When the increase button 71 or the decrease button 73 is pressed after the transposition switch 69 is operated, the pitch of the song is changed by a predetermined frequency when the automatic performance piano 21 reproduces the music.

Next, the keyboard 23 will be explained. Figure 4 is a plan view showing the correspondence between the keys constituting the keyboard and the characters, symbols, etc. in the song title input mode, and the keyboard 23 functions as a normal 88-key keyboard except in the song title input mode. In the one song name input mode used to issue a predetermined musical tone, the mode can be switched between English character mode and Katakana mode depending on the type of characters input. The correspondence is as shown in Figure 4.0For example, in the English character mode, the 39th key is used to press the English character "R".
You can enter the same number 391! In katakana mode, you can input the katakana character "i". Note that the 85th to 881a keys are used for forward movement of the cursor, and the 1st to 11th keys are used for backward movement of the cursor.

The configuration of the computer system that controls recording, playback, and input of song titles based on the operations of the switches on the operation panel and the keyboard 23, etc., is as shown in FIG.
The central processing unit 81 accesses the ROM 85 via the common bus 83 and sequentially reads and executes program instructions. The ROM 85 stores an operating system, a system initialization program, a main program shown in FIG. 6, and a subroutine program for inputting song titles, etc. shown in FIG. 7. Therefore, in the song title input mode, the central processing unit 81 sends and receives data to and from the automatic performance piano 21 via the common bus 83 and the MIDI input/output 93, which will be described later. receive and receive data on
A code such as a character corresponding to the operated key is determined.

The working register 87 includes a code indicating the file area corresponding to the song number selected by the song selection/fast-forward and fast-reverse switch 49, a data code related to repeated playback set by the repeat switch group 55, a volume switch 65, and an increase and decrease switch. Data code regarding the volume value set by 71.73, data code regarding the tempo set by tempo switch 67 and increase/decrease switch 71.73, data code regarding tempo set by tempo switch 67 and increase/decrease switch 71.73, and during playback set by transpose switch 69 and increase/decrease switch 71.73. Addresses are assigned in advance so that data codes relating to pitches to be changed, character codes input using the keyboard 23 during the input mode, such as song titles, can be temporarily stored.

The DMA controller 89 directly accesses the floppy disk set in the floppy disk driver 91 via the common bus 83 under the control of the operating system, and in the playback mode, the DMA controller 89 directly accesses the floppy disk set in the floppy disk driver 91. 81, the performance information stored under the file name transferred from the working register 87 is sent from the MIDI input/output 93 to the automatic performance piano 21. On the other hand, in the recording mode, coded performance information generated based on key operations and pedal operations of the automatic performance piano 1 is written into a data storage area of a pre-specified file.

The switches 45, etc. provided on the operation panel of the controller 7 are periodically scanned by the central processing unit 81, and when any switch 45, etc. is operated, the operated switch 45, etc. is determined by software. , the corresponding data code used to change the program address is transferred to the working register 87. Also,
The data code etc. set based on the operation of the switches 45 etc. provided on the operation panel are processed by the central processing unit 8.1.
is read out periodically by the display controller 9.
5 is visually displayed on the song number display section 41 and liquid crystal display section 43.

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 33 is turned on, the computer system executes an initialization program in step P1.
), to initialize the system 6 Next, the floppy disk driver 91 is scanned to determine whether a floppy disk is set (step P2). Step P
While the determination in Step 2 is NO, the floppy disk driver 91 continues scanning and waits for the determination in Step P2 to be YES.When the determination in Step P2 is YES, processing related to the floppy disk, such as determining whether or not formatting is necessary, is performed. If necessary, the floppy disk is formatted (step P3).

When step P3 is completed and writing to and reading from the floppy disk becomes possible, the switch group 45 and the like on the operation panel are scanned.In other words, by such scanning, it is determined whether or not the song selection/fast forward/reverse switch 49 has been operated. A determination is made (step P4), and if the determination result is YES, the process moves to a reproduction subroutine program. On the other hand, if the determination result in step P4 is NO, it is determined whether or not the recording switch 45 has been operated (step P5), and if the determination result is YES, the program moves to the song title input subroutine and recording subroutine program. Then, encoded performance information generated based on key operations on the automatic performance piano 21 is written into a data storage area of a pre-designated file, or a song title, etc. is written into the file in which the performance information is written. On the other hand, if the determination result in step P5 is NO, the floppy disk driver 91 is scanned again to determine whether or not the floppy disk has been ejected (step P6); while the determination result in step P6 is NO, step P4 Steps from P6 to P6 are repeated to wait for transition to the playback subroutine program, the manual subroutine for song titles, and the recording subroutine program.On the other hand, if the judgment result in step P6 is YES, the process returns to step P2 and a new floppy disk is set. and waits for the judgment result of step P2 to be YES.

Next, the flow when the judgment result in step P5 is YES and the process moves to the song title input subroutine and recording subroutine programs will be explained based on FIG.

When a formatted floppy disk is set in the floppy disk driver 81 and the recording switch 45 is operated, a recording switch-on event occurs. Subsequently, it is determined whether or not the recording switch 45 has been operated again (step P11), and if the determination result of the step pH is no, that is, the recording switch 45 is not operated again and the song selection/fast forward/reverse operation is performed. When the switch 49 etc. is operated, the recording mode is set and recording processing is performed in various modes (step P12).On the other hand, if the judgment result of the step pH is YES, the song number is stored on the floppy disk in the song number display section 41. The first song number being played is displayed (step P13). Next, it is determined whether or not the song selection/fast forward/reverse switch 49 has been operated (step P14), and if the determination result in step P14 is YES, the song number stored on the floppy disk is changed by operating step P14. A judgment is made as to whether or not the last number has been passed (step P15), and if the judgment result is no, the song number to which the song name etc. are input is changed, and the changed song number is displayed on the song number display section 41. (Step P16
) and changes the file to which the one-character code is written (step P17).Next, it is determined whether or not the soft pedal 25 has been operated (step P18), and if the determination result in step P18 is YES, the character mode is changed.

For example, the mode changing means 11 is realized by the above steps P18 and P19, which change from the alphabet mode to the katakana mode (step P19).

Next, after changing the single character mode, the keyboard 23 is scanned to determine whether any key has been operated (step P
20), when the judgment result is NO, the process returns to step P14, and steps P14 to P20 are repeated to prepare for changing the song number again and changing the 1-character mode again, and when the key is operated, the judgment result in step P20 becomes YES. wait for it to happen.

Note that if the 1 music selection/fast forward/reverse switch 49 is not operated and the determination result in step P14 is NO, the program immediately skips step P18 (jumps over to determine whether or not the soft pedal 25 has been operated, and if the soft pedal 25 is not operated. , step P
If the result of the determination in step P20 is NO, the keyboard 23 is scanned without changing the character mode, and the determination in step P20 is made.

After the song selection/fast forward/reverse switch 49 and the soft pedal 25 have determined the song title and character mode, when any key is operated, the character code corresponding to the operated key is displayed. occurs, and characters, codes, etc. are displayed on the liquid crystal display section 43 according to the correspondence shown in FIG. 4 (step P21), steps P20 and P21 described above.
The symbol code generating means 13 is realized by this.

Next, it is determined whether or not the loud pedal 27 has been operated (step P22). If the determination result in step P22 is no, the process returns to step P20 and the characters that have already been input and are displayed on the liquid crystal display section 43 are displayed. Prepare for other modifications. On the other hand, if the determination result in step P22 is YES, it is determined that the characters etc. displayed on the liquid crystal display section 43 are intended by the performer, and the character code corresponding to the character is temporarily stored in the register 87. At the same time as saving (step P23), the address of the register is incremented (step P24).

In the following step, it is determined whether or not the stop switch 63 has been operated (step P25), and if the result of the determination is no, the process returns to step P18 in case characters or the like are to be input subsequently. In this way, steps P18 to P2
5 is repeated, and while incrementing the address of the register 87, input the song title corresponding to the song number selected in the alphabet mode and the katakana mode, such as "Beyer 777".

When the input of the song title is completed and the judgment result in step P25 becomes YES, the character code temporarily stored in the register 87 is transferred to the file label section corresponding to the file area selected in steps P14 to P17. (Step P26).

When the input of the song name is completed in this way, the process returns to the main flow shown in Figure 6 and waits for the first operation to be performed.
The code sending means 15 is realized by steps P14 to P17 to steps P22 to P26.

Subsequently, the recording switch 45 is operated again to record the step pH.
After the judgment result in step P15 becomes YES, the music selection/fast forward/reverse switch 49 is repeatedly operated and the judgment result in step P15 becomes YES.

Disc title input processing P27 starts.

In this disc title input process P27, the above steps P18 to P25 are repeated and the liquid crystal display section 4
The character code is temporarily stored at a predetermined address in the register 87 while displaying characters, symbols, etc. in step P25.In this way, the judgment result in step P25 is YES, and the input of the disc title 1, for example, "Original Song Shu" is completed. Then, the character code temporarily stored in the register 87 is written to the volume label of the floppy disk.

When the disc title and song title are written in this way,
Not only can a desired floppy disk be easily selected during playback, but also a desired song can be quickly found when selecting a song.

In the above embodiment, the automatic performance system is constructed 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.
