The switch detection circuit 16 is connected to a panel switch 17 provided on the operation panel. Timer 21 is C
It is connected to an interrupt terminal of the PU 10 and interrupts the CPU 10 at each set clock timing. The ROM 12 stores a program shown in a flowchart described later. A plurality of song data are stored in the RAM 13 in the format shown in FIG. 3, and registers, flags and the like are set. Key press detection circuit 1
4 detects on / off of each key of the keyboard 15 and touch data. The switch detection circuit 16 is a panel switch 17
Is turned on. The panel switch 17 includes the function switches 31 to 33 and +/- switches 34 and 35 shown in FIG. 2, and further includes a play switch and a stop switch. The display circuit 18 is an LCD display 30 shown in FIG.
And controls the display contents. The tone generator 19 has a plurality of tone generation channels, and forms tone signals based on parameters input from the CPU 10. The formed tone signal is input to the sound system 20 and output from the speaker.

FIG. 2 is a diagram showing a partial configuration of an operation panel surface and an example of display contents of an LCD display. FIG. 7A shows a display example during an automatic performance, and FIG. 6B shows a display example of a music order change mode during an automatic performance. Function switches 31 to 33, a plus switch 34, and a minus switch 35 are provided below and to the left of the LCD display 30.
The functions of the function switches 31 to 33 differ depending on the operation mode of the electronic musical instrument, and the functions at that time are displayed on the display 30 (40 to 43). In FIG. 7A, only the function switch 33 has a function during the automatic performance (SONGPLAY). When this switch is turned on, the music order change mode (NEXT SONG
Mode). In the music order change mode, the function switches 31 to 33 are respectively set to continuous performance (PL
(AY) switch, PAUSE switch, and mode release switch (EXIT switch). These functions are displayed on the display 30 (41 to 41).
43) is indicated to the user. When the plus switch 34 and the minus switch 35 are operated in the song order change mode, the song number of the song to be played next is changed (increase / decrease).
Is done. When the song number is changed, the display of the song number and the song name on the LCD display 30 is changed accordingly.

FIG. 3 is a diagram showing the format of song data stored in the RAM 13. This figure shows the format of only one song (SONG1). A header is stored at the beginning of the song data. The header is composed of tempo, time signature, next song data, next mode flag, and the like. In the sequence data following the header, a set of duration data and event data is stored in the order in which the music progresses, and an automatic performance is performed by sequentially reading out this data from the beginning. The next song data is a song number that is automatically played next to this song. If this data is 0, the next song is not specified, and the program stops when this song ends. The next mode flag is a flag indicating whether to start playing the next music as it is or to wait in a pause state before starting playing.

FIGS. 4 to 12 are flowcharts showing the operation of the automatic performance apparatus.

FIG. 4 shows a main routine. When the power of the automatic performance apparatus is turned on, first, an initialization operation such as resetting a register is executed (n1).
Thereafter, the automatic performance process (n2: FIG. 6), the panel switch process (n3: FIG. 7) and other processes (n4) are repeatedly executed. Other processes are operations such as main volume control during automatic performance.

FIG. 5 shows a timer interrupt operation. This operation is performed by the timer 21 based on the specified tempo.
This is an operation executed by an interrupt from the server. In this operation, 1 is added to the tempo clock register TC (n5).

FIG. 6 is a flowchart showing the automatic performance processing operation. This operation is executed during the automatic performance operation.
First, the play flag PLAY is 1 and the pause flag P
It is determined whether AUSE is 0 and the tempo clock register TC is 1 or more (n10, n11, n1).
2). The play flag PLAY is a flag that indicates that an automatic performance is being performed, and the pause flag PAUSE is a flag that indicates that a standby is being performed. Further, the tempo clock register TC is a register added by the timer interrupt operation as described above, and when it is larger than 0 (1 or more), it indicates a timing for performing the automatic performance processing. If the above condition is satisfied, the operation of n13 or less is executed, and if not, the process returns to the main routine.

At n13, the content of the tempo clock register TC is decremented by one. If there is duration data that matches the TIME register (time register that is accumulated based on TC), the corresponding event data is read out and output to generate a musical tone (n14). If there is no matching duration data, do nothing. When data is read, if the read data is end data, the operation proceeds to the operation of n17 and below. If the read data is not end data, T
1 is added to the IME register (n16) and the routine returns.

At n17, the value of the next song data NS is determined. If NS = 0, it means that the music to be played next has not been specified, so the play flag PLAY is set to 0.
(N23) and returns. If NS> 0, then NS is set in the song number register SONG to automatically perform the song of the song number NS (n1).
8). The header of the song data designated by SONG is read and output to each circuit section (n19). Next, the next mode flag NM is determined (n20). NM = 1
If so, the data of the header of the new song is set in NS and NM (n21), TC, TIME and NSMODE are cleared (n22) and the routine returns. This starts the automatic performance of the next song. On the other hand, when NM = 0, MS,
After setting the header data of a new song in NM (n
24) The Bose flag PAUSE is set (n2
5) Return. Automatic performance of the next song starts when the play switch is turned on.

FIG. 7 is a flowchart showing the panel switch processing. This operation is an operation of searching for an ON event of a panel switch and executing a process corresponding to the switch having the ON event. When the play switch is turned on, a play switch processing operation (n36) is executed. When the stop switch is turned on, the play flag PLAY is set to 0 (n37). When the function F1 switch 31 is turned on, an F1 switch process is executed (n38). If the function F2 switch 32 has been turned on, an F2 switch process is executed (n39).

When the function F3 switch 33 is turned on, an F3 switch process is executed (n4).
0). When the +/- switches 34 and 35 are turned on, +/- switch processing is executed (n41). If another panel switch is turned on, a corresponding switch process is executed (n42).

FIG. 8 is a flowchart showing the play switch processing. This operation is performed when the play switch is turned on. First, a play flag PLAY and a pause flag PAUSE are determined (n50, n55). PLA
If Y = 0, the PLAY is set (n51) to start the automatic performance operation from now on, and the song number SO
The header of the NG song data is read and output to each register or the like (n52). In this header, the next song data and the next mode flag are set to NS and NM, respectively.
(N53). Thereafter, the tempo clock register TC, the timing register TIME, and the mode flag NSMODE are cleared (n54) and the routine returns.
When the mode flag NSMODE = 0, the display 3
0 indicates the contents of FIG. 2A, and NSMODE = 1
At this time, the contents of FIG. On the other hand, PLAY
In the case of = 1 and PAUSE = 1, PAUSE is reset to release the pause and start playing (n56), and then the process proceeds to n54.

In the case of PLAY = 1 and PAUSE = 0, the process returns without any operation because the automatic performance is being performed.

FIG. 9 is a flowchart showing the F1 switch processing operation. First, the play flag PLAY is determined (n60). If PLAY = 1, the display mode flag NSMODE is determined (n61). NSMODE = 1
Is set to 1 in the next mode flag NM (n62). If NSMODE = 0, no function is assigned to this function key and the process returns. On the other hand, if PLAY = 0 at n60, the processing corresponding to the mode at that time is executed (n6
3) Return.

FIG. 10 is a flowchart showing the F2 switch processing operation. First, the play flag PLAY is determined (n65). If PLAY = 1, the display mode flag NSMODE is determined (n66). NSMODE =
If it is 1, the next mode flag NM is set to 0 (n67). If NSMODE = 0, no function is assigned to this function key and the process returns. On the other hand, when PLAY = 0 at n65, the processing corresponding to the mode at that time is executed (n6
8) Return.

FIG. 11 is a flowchart showing the F3 switch processing operation. First, the play flag PLAY is determined (n70). If PLAY = 1, the display mode flag NSMODE is inverted (n71). NS inverted
The display on the display 30 is switched according to the MODE (n72). On the other hand, if PLAY = 0 at n70, processing corresponding to the mode at that time is executed (n73).
To return.

FIG. 12 is a flowchart showing the +/- switch processing. When this switch is turned on, first, the play flag PLAY is judged (n80). PLAY =
In the case of 1, the operation of n81 or less is executed. PLAY =
If it is 0, the process corresponding to the mode at that time is executed (n86) and the process returns. In n81, NSMODE is determined. If NSMODE is not 1, no function is assigned to this switch, and the process returns. In the case of NSMODE = 1 is corresponding to the (+) to a switch that is turned on (n82), 1 is subtracted addition or 1 to next song register N S (n83, n8
4). Thereafter change the song number and Song to display contents indicated by N S (n85) returns.

In this embodiment, the song number NS of the song to be played next is recorded in the header of the song data. However, the order of the songs to be played may be stored separately from the song data.
