The control processing of the automatic musical instrument constructed as above will be described below with reference to the flow charts of FIGS.

FIG. 4 is a flowchart showing the processing procedure of the main routine.

First, various initial settings of the CPU 4, RAM 6, etc. are performed (step S1).

Next, key processing for detecting the operation state and sounding according to the operation of the key of the keyboard 1 is performed (step S
2), general switch processing for detecting the operation state of the general switches of the switch group 2 and reproducing / stopping song data or chain data in accordance with the operation state (step S3), and the mode-compatible switch of the switch group 2 Three processing modes are discriminated according to the operation mode designated by (step S4), and the song creation mode (mode 1)
If so, the song creation processing described later is performed (step S
5) In the chain / division mode (mode 2), the below-described chain / division processing is performed (step S6), and in the edit mode (mode 3), the later-described edit processing is performed (step S7).

Here, the designation of each mode 1 to 3 is performed by the mode switch corresponding to each mode 1 to 3 as described above. Therefore, when the mode switch is pressed, the state of the mode switch is detected by the general switch process of step S3, and the process shifts to the mode corresponding to the detected state by the determination of step S4.

FIG. 5 is a flow chart showing the detailed procedure of the song creation processing subroutine which constitutes the song creation processing of step S5 of FIG. 4, and this subroutine is for creating the respective song data S1, S2, ... Is performing real-time recording processing. When the recording start switch (not shown) of the mode corresponding switches is pressed when the operation mode is the mode 1, this subroutine process is called.

First, when a new recording song number is designated (step S11), recording start processing corresponding to the song number is performed (step S12). Here, the designation of the song number in step S11 may be automatically set by the CPU 4 in the order of recording, or may be set by the number designated by the operator. In addition, the recording start processing in step S12 is, for example, data (hereinafter,
"Duration data") is a process for setting a resolution per bit, a process for selecting whether or not to generate a metronome sound during recording, a process for determining a writing position on the RAM 6, and the like.

Next, after the recording / writing process is performed (step S13), it is determined whether or not an instruction to end the recording is given (step S14). Here, in the recording / writing process, an on-event corresponding to the key depression by the operator is written, and a sounding process is performed. Therefore, the recording processing of step S13 includes the key processing. An instruction to end recording is given by a recording stop switch (not shown) of the mode corresponding switches.

When it is determined in step S14 that the recording end instruction has been issued, the process proceeds to step S15. On the other hand, when the recording end instruction has not been issued, the process returns to step S13 to repeat the recording / writing process.

In step S15, after the recording end processing is performed, this subroutine processing is ended. Here, the recording end process is a process of creating a header, specifically, a process of calculating the capacity of the song, the total number of measures, and the song number from the recorded data and storing it in a predetermined position. The song capacity is information required for storage on the external disk 7 or floppy disk (not shown) shown in FIG. 1, and the total number of measures is determined by connecting the songs by the chain function as described above. This is information necessary when creating the bar number table MNT at that time.

6 and 7 are flow charts showing the detailed procedure of the chain / division processing in step S6 of FIG. This processing is composed of two subroutines, one is the chain creation processing subroutine of FIG. 6 and the other is the song data division processing subroutine of FIG. If the chain switch (not shown) of the mode corresponding switches is pressed when the operation mode is mode 2, the chain creation processing subroutine is called,
When a division switch (not shown) of the mode corresponding switches is pressed, a song data division processing subroutine is called.

In the chain creation processing subroutine of FIG. 6, first, the chain number of the chain to be created is specified (step S21), and the write position for writing the chain data is specified (step S22). here,
The designation of the chain number in step S21 may be automatically set by the CPU 4 in the recording order, or may be set by the number designated by the operator. Further, the writing position in step S22 is the CPU
4, the empty area of the RAM 6 is searched and its position is automatically designated.

Next, the chain order is designated (step S23), and the song number is designated (step S2).
4) and the designated song number in the designated order (area CDn (k)). That is, for example, when "2" is designated as the chain number, the second position is designated as the connecting position of the chain C2, and "1" is designated as the song number, as shown in FIG.
“1” is stored in (2).

Next, it is judged whether or not the setting is completed (step S25), and if it is desired to continue the setting, the process returns to the step S23 to continue the setting process, and when the setting is completed, the number of connected chains is Writing to the area CNn (step S26), and this subroutine processing is ended.

Next, in the song data division processing subroutine of FIG. 7, the song number of the song to be divided is designated (step S31), the division position (point) in the song is designated (step S32), and the division after division is performed. When the song number of each song is designated (step S33), a plurality of newly numbered songs are generated by dividing at the song division points designated in each of steps S31 to S33, and the RAM 6 Is recorded at a predetermined position (step S34). Here, step S
The song number after division of 33 may be freely set by the operator from among unused numbers, or an unused number may be automatically retrieved by the CPU 4 and assigned. Good.

Next, when a new chain number is designated (step S35), the sequence of song numbers is stored as the chain data of the designated chain number in the order designated in step S33 (step S35). S3
6) After that, this subroutine processing is ended. That is, FIG.
A chain consisting of the number of chains and a plurality of chain numbers as described in 1. is generated and stored.

8 and 9 are flow charts showing the detailed procedure of the edit process of step S7 of FIG. This process is mainly composed of a song data edit process subroutine shown in FIG. 8 and a chain song edit process subroutine shown in FIG.
If the song data edit switch (not shown) of the mode corresponding switch is pressed when the operation mode is mode 3, the song data edit processing subroutine is called, and the chain song edit switch of the mode corresponding switch (Fig. When (not shown) is pressed, the chain song edit processing subroutine is called.

In the song data edit processing subroutine of FIG. 8, the operator specifies the song number to be edited (step S41), and the bar position and beat position to be edited in the song (step S42). Edit processing is performed from the designated measure (step S43). Here, step S4
The edit processing of 3 specifically includes processing such as pitch change, tone change, and dynamic change. When the song number to be edited and its bar position and beat position are specified in steps S41 and S42,
The bar of the song number is read from the songs S1, S2, ... And is displayed on the display 3 of FIG. 1, and the cursor is moved to the beat position so that the beat can be edited.

In the chain song edit processing subroutine of FIG. 9, when the operator specifies the chain number to be edited (step S51), the bar position and the beat position are specified (step S52), the chain number is specified in step S51. The number of bars of each song in the chain is detected to create the bar number table MNT (step S53), and the song number corresponding to the playback start bar specified in step S52 from the bar number table MNT thus created. And the bar position in the song are calculated (step S54).

An example of the bar number table MNT created in step S53 is shown in FIG. 2 for the chain C2. That is, the total number of measures of each music is arranged according to the order of the connected music. Then, for example, in steps S51 and S52, 8 in the chain C2
When the third beat of the bar is designated, first, "4" is subtracted from "4" (the first table data of the bar number table MNT), and then the subtraction result "4" to "6".
(The second table data of the bar number table MNT) is subtracted. At this time, since the subtraction result is a negative value, the target bar position is found to be the fourth bar of the second stored song number, and the song data of the fourth bar of the song number is read. It is emitted and displayed on the display device 3, and the cursor moves to the designated beat position.

Then, after the edit processing is performed from the bar position of the song number designated in the step S54 (step S55), this subroutine processing is ended.

The bar position designation in the above-described editing process is not only performed for changing the timing, pitch, duration data, etc. of the automatic performance data in the bar, but the copy is performed by designating a range. , Deletion, and insertion and the like may be performed.

FIG. 10 is a flow chart showing a procedure of a song reproduction processing subroutine for reproducing recorded or edited song data. One of the general switches
When a switch for instructing reproduction for each music piece is pressed, this subroutine process is called. When the song number is designated (step S61) and the playback start position is designated (step S62), the playback start initialization process is performed (step S63), and then a timer interrupt timer is started (step S64).

Here, in the initial setting process of the reproduction start in step S63, since the tempo change, the tone color change, etc. are generally included in the middle of the music, the process of reading the information from the header data and setting the information. , There is a process of setting the time of the reproduction start position in the counter CNT which counts the output timing of the ON event.

FIG. 11 is a flow chart showing the procedure of a chain playback process for playing back a recorded or edited chain song. When a switch (not shown) for instructing the reproduction of the chain function of the general switch is pressed, this subroutine process is called.

First, a chain number is designated (step S71), and a reproduction start position is designated (step S7).
2) and the number of bars of each song in the specified chain is detected to create the bar number table MNT (step S
73), from the created bar number table MNT, the song number and the bar position within the song corresponding to the playback start bar designated in step S72 are calculated (step S74).

Next, the setting process necessary for reproduction from the bar position of the song number calculated in step S74, for example, the setting process of the value of the counter CNT corresponding to the bar position, etc. is performed (step S75). ), The timer is started (step S76).

FIG. 12 is a flow chart showing the detailed procedure of timer interrupt processing.

In this embodiment, the timer interrupt request is made by the timer 8 at a predetermined time (tempo), for example, once every 96 minutes. That is, when the timer 8 measures a predetermined time, the CP
The interrupt request is output to U4, and the CPU 4 receives the interrupt request and shifts the processing from the main routine to the timer interrupt routine. Since this time changes according to the change in tempo, the time interval at which an interrupt request is made changes depending on the tempo.

First, the counter CNT is incremented by "1" (step S81), and an event to be reproduced is reproduced according to the value of the counter CNT (step S82). The reproduction process in step S82 is
Specifically, it refers to a process of transmitting an on event, an off event, tone color data, etc. to the sound source of FIG.

Next, it is judged whether or not the end time of the song being reproduced has come by the value of the counter CNT (step S83). When the end time has not come, this interrupt processing is ended, while the end time is ended. When it becomes, it progresses to step S84.

In step S84, it is determined whether or not the current reproduction process is the chain reproduction process, and if it is the chain reproduction process, it is determined whether or not the chain to be reproduced has ended (step S85), and the reproduction is still performed. When there is a chain to be played, the reproduction start initialization of the song next to the chain is initialized (step S86), and the counter CNT is set.
After resetting (step S87), this interrupt processing is terminated.

On the other hand, if it is determined in step S84 that the editing process is not being performed, or if the determination in step S85 is that the chain to be reproduced has ended, the timer is stopped and the timer interrupt is prohibited (step S8).
8) After that, this interrupt processing is ended.

In the reproduction of the chain song by the timer interrupt processing, the automatic performance data (musical score information) currently being reproduced is displayed on the display unit 3. At this time, at the joint between the song and the song. The page to be displayed may be changed or may be continuously displayed without being changed.

It should be noted that the reproduction process is stopped by pressing a switch for instructing to stop the general switch for each song and a switch for instructing to stop the chain function.

In addition, the bar numbers throughout the chain are displayed during the playback process. In addition to this, bar numbers in each song are displayed, and one of them can be selectively displayed or both of them can be displayed together. May be. Further, during the editing process, either one of the bar numbers throughout the chain or the bar numbers in each song may be selectively displayed, or both may be displayed together.

Although the present embodiment describes an example in which the song numbers constituting the once set chain cannot be changed, the present invention is not limited to this, and the once set chain can be changed by a predetermined switch operation. May be.

As described above, according to this embodiment,
Since a plurality of songs can be handled as one song by the chain function, the operability during editing can be improved and the visibility during playback can be improved.

Further, since one song is divided into a plurality of songs and managed and stored, a desired phrase can be stored as song data so that it can be read out later and used freely. You can record each phrase, store it as a separate song, and finally chain it into one song.

Furthermore, since this embodiment has an edit function, it is possible to easily edit a specific phrase by dividing the recorded song into songs for each phrase. Then, store the phrase after editing as a song different from the phrase before editing, and if you prepare both a chain that specifies that phrase before editing and a chain that specifies that phrase after editing, You can compare and view before and after editing a phrase.

Further, for example, a song that is too large to fit in the performance data memory of the automatic playing device is divided into a plurality of smaller songs, and the songs are stored in a mass storage device such as a hard disk. By performing editing and reproduction by, it is possible to operate the automatic performance device as if it had a super huge performance data memory.
