Abstract
An automatic rhythm performing apparatus comprises a rhythm pattern generator for generating stressed beat pattern pulses representative of stressed beats of a rhythm to be generated and relaxed beat pattern pulses representative of relaxed beats of the rhythm, a tone generator, a rhythm gate coupled to the tone generator and a mute gate coupled to the rhythm gate. The rhythm gate is operative to impart a decayed envelope to a tone signal from the tone generator in reponse to each of the stressed beat pattern pulses and the mute gate is operative to suppress a portion of a decayed output signal from the rhythm gate in response to each of the relaxed beat pattern pulses. The automatic rhythm performing apparatus can be used for an automatic chord performance of a keyboard type electronic musical instrument.
