If it is desired to perform the fill-in performance only with the rhythm sound, if the same operator is pressed again while the LED 25 is lit as described above, the LED 25 will blink, and no musical sound will be generated in the amplifying section. Is set so that only the musical tone of the rhythm section is generated. When the assignable switch 8b on the right side is operated in this state, only the rhythm part is played in the fill-in pattern even after the tone generation of the accomp is set, and the normal pattern performance is returned after the fill-in performance is completed.

The blinking state of the LED 25 is maintained as long as the fill-in selection operators F1 to F3 are not operated thereafter. By operating the assignable switch 8b, the fill-in performance of only the rhythm sound is continuously performed for two or more measures. Can be easily done. On the other hand, if the same operator is pressed again while the LED 25 is blinking, the LED 2
5 returns to the lighting state again, and is again set so that all the set parts are played in the fill-in pattern.
As described above, each time the same fill-in selection operation element is operated, the lighting state and the blinking state of the LED 25, that is, the mode of setting the musical tone of the amplifying section to the sounding state or the non-sounding state is alternately switched.

As described above, according to the present embodiment, when performing a fill-in performance of only the rhythm sound during the execution of the automatic accompaniment including the accompaniment sound, the fill-in selection operators F1 to F3 are used. Only one of them can be set in such a state, and a plurality of operators M1 to M2,
It is not necessary to operate B1 to B2 and BASS.

Thus, the operation for performing the fill-in performance of only the rhythm sound while the automatic accompaniment including the accompaniment sound is being performed can be simplified.
In addition, since the fill-in performance of only the rhythm sound can be realized even when operated at any time during the performance, there is an advantage that the setting can be freely changed according to the ad-lib of the player.

In the above-described embodiment, the LED 25 is turned on or off in response to the mode switching. However, if the display mode changes according to the mode, the present invention is applied to such a case. It is not limited to the embodiment. For example, a method of changing the display color according to the mode may be used, or a display device other than the LED or other notification means may be used.

In this case, all the LEDs 25 are turned off at the start of the performance, and during the performance, the fill-in selection operator F
When any one of 1 to F3 is pressed, the LED 25 provided corresponding to the pressed operator is turned on, and the performance of the selected fill-in pattern is started. In this case, both the acamp section and the rhythm section are played in a fill-in pattern. Then, after the fill-in performance ends, the operation automatically returns to the normal pattern performance, and the LED 25 is also turned off.

The fill-in performance starts simultaneously with the lighting of the LED 25 when the fill-in selection operators F1 to F3 are pressed during the period from the first beat of the bar to immediately before the last beat. On the other hand, when the fill-in selection operators F1 to F3 are pressed within the last beat of a bar, it is difficult to determine whether or not the operation was performed in the next bar. The fill-in performance starts from the beat of.

When the same fill-in selection operator is pressed again within the last beat of a bar while the LED 25 is turned on, the LED 25 flashes, indicating that only the rhythm section is in the sound emitting mode. . Normally, one fill-in selection control is continuously applied within the last beat of a bar for 2 times.
By pressing the button twice, the mode is set so that only the rhythm section is in the sound emitting state. In this mode, the fill-in performance of only the rhythm sound starts from the first beat of the next bar, and after the fill-in performance is completed, it automatically returns to the normal pattern performance,
The LED 25 is turned off.

When the LED 25 is blinking (when the fill-in performance of only the rhythm sound is being performed), the same fill-in selection operation element is operated, and the LED 25 is turned on.
25 can be turned on (in this case, the fill-in performance of only the rhythm sound is continued until the end), and by operating the same fill-in selection operator again within the last beat of the fill-in performance, the rhythm can be changed. It is possible to perform fill-in performance of only sound continuously.
