a rhythm pattern generation circuit 5 from which required rhythm patterns are read out by the sequential pulses; and an address signal that designates a read address so as to switch the rhythm patterns read from the rhythm pattern generation circuit 5 in an irregular order. A pulse corresponding to one beat is input as the first clock pulse from among the divided pulses of the rhythm pattern designation circuits 1 and 4 and the sequential pulse generation circuit 9, and the address signal from the rhythm pattern designation circuits 1 and 4 is inputted. controlled by
a pulse counting circuit 10 for applying a second clock pulse having a period corresponding to the number of beats necessary for playing a predetermined rhythm pattern to the pulse generating circuit 1 in the rhythm pattern specifying circuits 1 and 4; The circuit 10 includes a counter SR which inputs the first clock pulse.
and a logic operation circuit A that operates on the output signal corresponding to the required number of beats from the counter SR and the address signals from the rhythm pattern designation circuits 1 and 4.
1, A2, and O2, and the second clock pulse is generated by the logical operation circuit.
