Abstract
An electronic musical tone synthesizing apparatus includes a damper pedal and an envelope generator. The envelope generator imparts an envelope to a musical tone to be produced. When the termination of the musical tone is designated, the envelope generator imparts a decaying envelope thereto. If the damper pedal is depressed during the processing of the decaying envelope, the decaying rate becomes slower. This leads to the performance of sustaining effects such as in an acoustic piano.
