Therefore, there is no need to provide a new switch or the like for the initial setting. Furthermore, since the initial setting memory groups 15A, 15B, and 15C are read-only, there is no possibility that the stored contents will be destroyed. Therefore, the initial setting is performed reliably.

In the embodiment described above, the accompaniment mode designation switch 8a.

By using 8b and 8c as specific function switches, one or more performance information memory groups 4A, 4B,
Although the initial settings of 4C are performed, any one of the plurality of function switches provided on the operation panel of the electronic musical instrument may be used as the specific function switch for performing the initial settings.

〔Effect of the invention〕

According to the electronic musical instrument of the present invention, a read-only initial setting memory group storing initial setting values for each performance information is provided for each of the plurality of performance information memory groups provided for each of the plurality of types of performance information. The stored contents of the setting memory group are written into the corresponding performance information memory group by a writing means activated by turning on the power accompanied by the operation of a specific function switch among the plurality of function switches of the electronic musical instrument. One or more performance information memory groups are associated with the specific function switch in advance, and when the power is turned on accompanied by the operation of this specific function switch, the initial information is stored in the associated performance information memory group. Initial setting values in the setting memory group are written. In this way, initial settings can be made not for each memory but for each group of one or more predetermined performance information memories. Therefore, when the stored contents of the performance information memory group are destroyed, by performing the above initial settings, it becomes possible to restore the contents easily and quickly, thereby significantly improving the operability of the electronic musical instrument. Moreover, since the initial setting is performed by operating a specific function switch among the plurality of function switches used for playing the electronic musical instrument, there is no need to provide a new switch or the like for the initial setting.
