PURPOSE:To provide an inexpensive auto rhythm generator by constituting a rhythm decoder and timber generating circuit with an auto rhythm generating integrated circuit. CONSTITUTION:When rhythm selector signals enter a rhythn decoder 312, percussion drive signals are outputted and are then inputted to a control part 301, which in turn drives respective timber generating circuits. For example, with cymbals and high hat, envelopes are created with an ROM 304 and D-A converting part 305. The reference waveforms are determined by the white noise simulator 311 being inputted as the reference power source for the D-A converter. |
