Claims

[Scope of utility model registration request]

(1) A rhythm selection switch, a rhythm pattern memory in which drive data for each rhythm sound source is stored, a musical sound signal memory in which a plurality of musical sound signals of different types are stored for each sound source, and the rhythm pattern memory. an address generator for specifying a musical sound signal storage section of each sound source indicated by the sound source-specific drive data in the musical sound signal memory when the sound source-specific drive data of the rhythm selected by the rhythm selection switch is read from the above; An automatic rhythm performance device comprising: a memory selection signal generator that selects one musical tone signal storage section for each sound source among the musical sound signal storage sections of each sound source specified by the same address generator in synchronization with the operation of the generator. .

(2) Registration of a utility model characterized in that the memory selection signal generated by the memory selection signal generator is changed based on control data stored in the rhythm pattern memory in correspondence with the drive data for each sound source. An automatic rhythm playing device according to claim 1.

(3) Automatic rhythm performance according to claim 1, wherein the memory selection signal generated by the memory selection signal generator is changed based on a random signal generated by a random signal generator. Device.
