ABSTRACT:
A control circuit for controlling an automatic rhythm generating circuit of an automatic rhythm performance apparatus comprises a memory for controlling the rhythm start or stop operation of the automatic rhythm generating circuit by an output state, a rhythm performance control signal supply circuit including a plurality of rhythm performance control switches, and a logic circuit having inputs coupled to the outputs of the rhythm performance control signal supply circuit and to the outputs of the memory and having outputs coupled to the inputs of the memory. The state of signals at the outputs of the rhythm performance control signal supply circuit is variable by the operation of the control switches. The logic circuit causes the memory to be set from one output state to another state in response to a variation in the state of signals at the outputs of the rhythm performance control signal supply circuit.
