ABSTRACT:
An electronic musical instrument comprises a circuit for generating a stepwise envelope waveform which modulates a musical tone waveform signal, a detecting circuit for detecting the phase of the musical tone waveform signal where the amplitude of the musical tone waveform signal becomes the zero level, and a control circuit for bringing the amplitude of the envelope waveform to be at the zero level in synchronization with the detection of that phase of the tone signal by the detecting circuit if generation of the envelope waveform is to be finished, thereby to eliminate the generation of click sounds.
