[Detailed description of the invention] "Industrial application field" This invention controls an automatic performance device or the like that generates musical tones based on performance information stored in a storage medium in accordance with a preset performance schedule. The present invention relates to a performance control device for an automatic musical instrument suitable for use in a musical instrument.

2. Description of the Related Art Conventionally, in an automatic musical instrument such as an automatic piano, performance data stored in an external storage means or a memory is sequentially read out by a built-in performance control device or an externally connected general-purpose sequencer, and reproduced based on the performance data. Was performing.

In such an automatic musical instrument, for example, in an automatic piano, a key is driven by driving a key driving solenoid provided for each key based on performance data to generate a musical tone. The automatic reproduction performance in this case tends to last for a long time because the performance is continuously performed by the performance control device or the general-purpose sequencer. Therefore, there is a problem that the deterioration of the automatic piano is accelerated as compared with a general acoustic piano. Further, since the conventional performance control device, general-purpose sequencer, and the like do not have a timer function as described above, the date and time, start time, performance time, interval time, and the like of the reproduction performance cannot be set. For this reason, there is a problem that it is not possible to respond to a request to automatically play and play some different songs.

Therefore, conventional performance control devices and general-purpose sequencers are provided with a timer function and the like for limiting the performance time, and the timer measures the interval time based on the music number and the interval time of the performance music. According to the performance data stored in the external storage means,
There is an automatic musical instrument that can start and end an automatic performance. Incidentally, this kind of technique is disclosed in Japanese Patent Application Laid-Open No. 1-302593.

[Problems to be solved by the invention] By the way, in the above-mentioned automatic musical instrument, there is a limitation in music selection for one disk, and therefore, when performing a wide range of music selection for performance data stored on a floppy disk, the It has to be replaced, which causes a problem of poor operability.

In addition, since performance data cannot be edited in advance over a plurality of floppy disks, for example, when there are different songs having the same file name in different floppy disks, it is difficult to continuously reproduce and play them. Was. That is, the degree of freedom of the reproduction performance is limited.

This invention was made in view of the above-mentioned problems,
It is an object of the present invention to provide a performance control device for an automatic musical instrument, which has an improved editing function to increase the degree of freedom of reproduction performance and has excellent reliability and operability.

"Means for Solving the Problems" In order to solve such problems, the present invention provides a detachable first storage means and a second storage means having a larger storage capacity than the first storage means. Transfer means for transferring the performance data stored in the first storage means to the second storage means; and selecting any performance data from the performance data stored in the second storage means. Selecting means for performing, performance condition storage means for storing a plurality of performance conditions including at least performance data instruction data indicating performance data selected by the selection means and start time data indicating performance start time, and the performance condition storage means In accordance with the performance data indicated by the performance data instruction data of each of the plurality of performance conditions in accordance with the respective start time data of the plurality of performance conditions stored in the storage device. Means,
It is characterized by having.

According to the invention, the operator transfers the performance data stored in the first storage unit to the second storage unit,
Using the selection means, any performance data is selected from the performance data stored in the second storage means, and at least performance data instruction data indicating the selected performance data and start time data indicating the performance start time. Are stored in the performance condition storage means. Then, the control means, at a desired time according to the start time data of each of the plurality of performance conditions stored in the performance condition storage means, performs the performance indicated by the performance data instruction data of each of the plurality of performance conditions. Performances are sequentially performed based on the data. As a result, it is possible to perform a plurality of desired songs at a desired time for each song, and when setting performance data to be used for timer performance, the first storage means is exchanged for each song. Saves time and improves operability. Further, since the timer performance is performed based on the performance data transferred to and stored in the second storage means, a plurality of music pieces stored in the plurality of first storage means can be continuously played. In addition to this, it is possible to select a wide range of music from a plurality of performance data stored in the second storage means, and it is not necessary to replace the first storage means even during a performance.

* ”, And the current time is displayed in the lower right.
A cursor is displayed at the position of the current time to be set, and the cursor is moved by pressing the "" and "" keys.

Next, in step SD2, it is determined whether or not the "clock adjustment" key is continuously pressed. If the result of the determination in step SD2 is "NO", that is, if the "clock adjustment" key is not continuously pressed, the process proceeds to step SD3. In step SD3, the set time [hh (hour): mm (minute): ss (second)] is input from the ten keys. Next, the process proceeds to Step SD4, and Step S4 is performed.
In D4, it is determined whether or not the "clock adjustment" key is pressed. If the result of the determination in step SD4 is "NO", the process returns to step SD1 and the previously input time is displayed on the display unit 5. Then, step SD2 described above is executed again.

On the other hand, in step SD2, the determination result is “YES”.
In other words, if the "clock setting" key is continuously pressed, the process proceeds to step SD5. In step SD5, it is determined whether the "SET" key has been pressed. If the determination result in step SD5 is "NO",
Step SD5 is repeatedly executed. Then, when the user presses the “SET” key in accordance with another reference time signal or the like, the determination result in step SD5 becomes “YES”, and the flow advances to next step SD6. In this step SD6, [hh (hour)] and [mm
(Minutes)] and [ss (seconds)] are cleared to “00” and confirmed. Then, the program ends.

(5) Manual / Automatic Playback Performance Mode FIG. 14 is a flowchart (main routine) showing the operation of the CPU 1 in the performance control device 15 in the manual / automatic playback performance mode. FIG. 15 is a diagram showing a display example of the display unit 5 in the manual / automatic reproduction performance mode. This main routine is started when a power switch (see FIG. 4) of the performance control device 15 is turned on. When this main routine is started, the process first proceeds to step SE1, and the "hard disk" or "floppy disk"
Determine which of the keys is on. And
When the "floppy disk" key is on, the determination result in step SE1 is "NO", and the
Proceed to E2. In step SE2, the target of the playback performance mode is changed to a floppy disk. And step SE2
Is completed, and if "hard disk" is on in step SE1, the process proceeds to step SE3.

Then, in step SE3, the title and song name of the target disc are displayed (FIG. 15 (a),
(B)). FIG. 5A shows the case of a floppy disk, and FIG. 5B shows the case of a hard disk.

Next, proceeding to step SE4, a TEMPO input setting process for setting the tempo TEMPO of the performance is performed. The input of the tempo TEMPO in step SE4 is performed by pressing the "+" key while increasing the value while pressing the "tempo" key, or decreasing the value by pressing the "-" key to obtain a predetermined value. Done. In this example, the tempo TEMPO is-
The value can be selected in the range of 5 to +5, and once set, the value becomes effective thereafter.

Next, the process proceeds to step SE5. In step SE5, it is determined whether or not the mode is the automatic reproduction performance mode. In the initial setting, the automatic reproduction performance mode is set. That is,
At this point, it is determined whether the "AUTO" key shown in FIG. 4 is in the ON state. If the "AUTO" key is not on, that is, if the mode has been switched to the manual reproduction performance mode, the result of the determination in step SE5 is "NO", and the flow proceeds to step SE6. This step SE6
Then, it is determined whether the "volume" key has been pressed. If the “volume” key has not been pressed, step SE6
Is "NO", and the process returns to step SE5. Therefore, steps SE5 and SE6 are repeatedly executed until the "AUTO" key or the "volume" key is pressed. When the "volume" key is pressed in this loop, the result of determination in step SE6 is "YES".
, And the process proceeds to Step SE7. And this step SE7
Thereafter, the mode becomes the manual reproduction performance mode.

[Manual Playback Performance Mode] Next, the manual playback performance mode will be described. First,
In step SE7, the volume VOLUME during the performance is input and set from the operation unit 7. The input of the volume VOLUME is performed by pressing the "+" key while increasing the value while pressing the "volume" key, or decreasing the value by pressing the "-" key to obtain a desired value. In this example, the volume VOLUME can be selected in the range of +3 to -8.

Next, the process proceeds to step SE8, where music selection processing is performed. If the target of the playback performance mode is a floppy disk,
Music selection is performed by the "" and "" keys on the screen shown in FIG. 15 (a). When the player presses the "" key once, the program advances one song forward, and the song number and title are displayed on the display unit 5. Pressing the "" key once returns to the previous song. Then, the song displayed at that time is set as a performance song.

When the object of the playback performance mode is a hard disk, the selection of a tune is made on the screens shown in FIGS. 15 (c), (d) and (e) by using "+", "" instead of "", "".
This is performed by the "-" key. First, in FIG. 15 (c), scroll the screen up and down using the "+" and "-" keys, move the cursor to the desired disc number, and press the "SET" key. All songs of the disc number are selected. In addition, "PLAY / PAU
When the "SE" key is pressed, all the songs with the above disc numbers are set as performance songs. The number of disc numbers to be selected may be plural, and a mark "*" is attached to the selected disc number. (See FIG. 15 (d)).
Then, at this point, if you press the “SET” key,
All songs with the disc number marked with “*” are set as performance songs. After the mark "*" is added to the desired disc number, the cursor is moved to the number of music pieces by the "" key and the "SET" key is pressed, and the screen changes to the screen shown in FIG. 15 (e). On the screen shown in this figure, the disc title and the song name of the corresponding disc number are displayed. On this screen, when the cursor is moved to a desired song number and the "SET" key is pressed, the song is set as a performance song.

Next, the process proceeds to step SE9, where a repeat setting process for designating the number of repetitions of the music piece is performed. To specify the number of repetitions, use the “one-track repeat” key or the “all-track repeat” key.
This is done by pressing a key. When the "one song repeat" key is pressed, only the song of the song number displayed on the display unit 5 at that time is set so as to be repeatedly performed. When the "ALL REPEAT" key is pressed, all the tunes stored on the disc are played in sequence, and when the last tune is reached, the first tune is set to be repeated again.

Next, the process proceeds to Step SE10. In this step SE10,
It is determined whether the "PLAY / PAUSE" key is on.
The "PLAY / PAUSE" key is a key for instructing the start of performance in the manual reproduction performance mode. If the "PLAY / PAUSE" key is not pressed in this step SE10 (PLAY is instructed if the LED of the key is lit), this step SE10 is repeatedly executed. When the “PLAY / PAUSE” key is pressed, this step SE1 is executed.
The determination result of 0 is “YES”, and the flow proceeds to Step SE11. In this step SE11, power-off prohibition processing is performed, and the routine proceeds to the next step SE12. In step SE12, the solid state relay 14 shown in FIG. In the manual reproduction performance mode, power supply may be continued.

Next, the process proceeds to step SE13, where the performance information of the disc is read, converted into a MIDI signal through the output interface 12, and output to the automatic piano 20. The automatic piano 20 generates a musical tone by driving a key driving solenoid provided on each keyboard based on the MIDI signal. While the performance information is being supplied to the automatic piano 20, step SE14 is executed.
, It is determined whether the "STOP" key has been pressed or the reproduction performance has ended. This step SE14
Is "NO", the playback performance by the automatic piano 20 in step SE14 is continued. Step SE14
Is "YES", that is, when the playback performance ends or the "STOP" key is pressed,
Proceed to step SE15.

Next, in step SE15, a process of canceling the power-off prohibition is performed, and the process proceeds to step SE16. In step SE16,
It is determined whether or not the current time is a preset power-off time (the power-off time described above). If the result of the determination in step SE16 is "YES", the flow proceeds to step SE19. In step SE19, the power supply to the automatic piano 20 is stopped, and the program ends.

On the other hand, if the result of the determination in step SE16 is "NO", the flow proceeds to step SE17. In step SE17, it is determined whether or not the maximum continuous playback time has elapsed since the end of the playback performance. If the result of the determination in step SE17 is "YES", that is, if the maximum continuous playback time has elapsed, the process proceeds to step SE19, in which the power supply to the automatic piano 20 is stopped, and the program ends.

If the result of the determination in step SE19 is “NO”, that is, if the maximum continuous playback time has not yet elapsed, the process proceeds to step SE18. In step SE18, it is determined whether any key is input. This is to determine whether or not the operator is about to execute the next process based on the presence or absence of a key input. Therefore, if any key is input and the result of determination in step SE18 is "YES", the flow returns to step SE5, and waits for an instruction for the next music selection or automatic reproduction performance. Further, when the determination result in step SE18 is “NO”, that is,
If there is no key input after the end of the playback performance, a loop consisting of step SE16, step SE17 and step SE18 is repeatedly executed, and the power-off time is reached in step SE16, or the maximum after the end of the playback performance in step SE17. It is determined whether or not the continuous reproduction time has elapsed. When one of the determination results is “YES”, the process proceeds to step SE19, in which the power supply to the automatic piano 20 is stopped, and the program ends.

On the other hand, if the "AUTO" key has been pressed beforehand (initial setting) before the "POWER" key is pressed, or if the automatic playback performance mode is set after the power is turned on, the determination result in step SE5 is "YES". , And the process proceeds to Step SE20.
Then, after step SE20, the automatic reproduction performance mode is set.

[Automatic Playback Performance Mode] Next, the automatic playback performance mode will be described. First,
In step SE20, a message indicating that the automatic reproduction performance mode has been selected is displayed. Next, step SE
Proceed to 21 to perform power-off prohibition processing. And step S
At E22, preset reproduction performance conditions (various performance conditions set in the above-described program setting mode) are stored in the hard disk 19b or the backup RAM 11.
Read from. The playback performance conditions include the day of the week
There are song number, volume VOLUME and playing time. Then, in step SE23, electric power is supplied to the automatic piano 20, and the process proceeds to the next step SE24. In step SE24, performance information is supplied to the automatic piano 20 in accordance with the above-mentioned reproduction performance conditions. The automatic piano 20 generates musical tones based on performance information. While the performance information is being supplied to the automatic piano 20, it is determined in step SE25 whether or not the "STOP" key has been pressed. The "STOP" key is for temporarily stopping the reproduction performance. And step SE25
In the case where the determination result is "YES", that is,
If the "STOP" key is pressed during the playback performance, the process proceeds to step SE29, and the output of the performance information is temporarily stopped. Then, the process proceeds to the next Step SE30, and it is determined whether or not the “PLAY” key is pressed. If the result of the determination in step SE30 is “NO”, the flow returns to step SE29. That is,
After the "STOP" key is pressed, the playback performance is temporarily suspended until the "PLAY" key is pressed. When the "PLAY" key is pressed and the result of determination in step SE30 is "YES", the flow proceeds to step SE31. In this step SE31, it is determined whether or not the counter value has passed a preset performance time. Then, in step SE31, if the result of the determination is "NO", that is, if the counter value has not yet reached the playing time, the process returns to step SE24, and again
The performance information is output according to the playback performance conditions, and the automatic piano 20
To generate musical tones. If the result of the determination is "YES" in step SE31, that is, if the counter value has reached the playing time, the flow proceeds to step SE32.
In this step SE32, the reproduction tune is updated to the tune stored in the next reproduction performance step, and the process returns to step SE22.
Then, in step SE22, the playback performance conditions of the music piece of the new playback performance step are read from the hard disk 19b or the backup RAM 11. Hereinafter, the automatic reproduction performance is continued in the same manner.

On the other hand, if the decision result in the step SE25 is "NO", that is, if the "STOP" key is not pressed and the performance is not interrupted, the process proceeds to a step SE26. In step SE26, it is determined whether or not the automatic playback performance mode has been released, that is, "AUTO"
Determine whether the key has been pressed. And step SE
In step 26, if the result of the determination is "YES", the automatic reproduction performance is terminated, and the flow returns to step SE5 to execute a process of selecting a manual reproduction performance or an automatic reproduction performance. Hereinafter, processing similar to the above-described processing is performed. If the result of the determination is “NO” in step SE26, the flow advances to next step SE27. In step SE27, it is determined whether or not the music currently being reproduced and played has ended. Then, in step SE27,
If the result of the determination is "NO", that is, if the playback performance has not ended, the process returns to step SE22 to continue the playback performance.

If the result of the determination in step SE27 is "YES", that is, if the reproduction performance has already been completed, step SE27 is executed.
Proceed to 28 to release the power OFF prohibition. And step S
Proceeding to E19, the power supply to the automatic piano 20 is stopped, and the program ends.
