A musical tone generating apparatus includes a waveform generator for generating a musical tone signal corresponding to a desired musical tone based on a key-on event which occurs in a keyboard and an envelope generator for generating an envelope which controls the amplitude of the musical tone signal in response to the key-on event. When a key-on event occurs, the envelope generator compares the current value of the envelope with a predetermined value, and based on the result of this comparison, determines a initial value of the next envelope corresponding to the key-on event. Consequently, the musical tone generating apparatus can generate musical tones without generating a click noise even if the key-on event repeatedly occurs over time at short intervals.
