ABSTRACT:
An electronic musical instrument comprises a plurality of keys being displaceable relative to a support member therefor in response to depression thereof. A CPU detects velocity of depression of each of the keys from displacement of the each key caused by depression thereof, and also detects a pressure force or an impact force with which the each key urgingly contacts a stationary member at or near termination of depression of the each key. The CPU is responsive to the detected velocity of depression and pressure force or impact force, for determining initial touch information for a musical tone to be generated or at least one musical tone parameter, and for controlling the musical tone to be generated, based on the determined initial touch information.
