Abstract
A piezo pickup which detects a key depression vibration occurred by a key depression operation is provided on the center of the lower surface of a key switch board where key switches of a keyboard are arranged. A CPU acquires the key number of a depressed key and a distance between the key switch of this key number and the piezo pickup in response to the key depression operation, and controls the sound volume and the tone color of a musical sound at a pitch corresponding to the key number based on control data acquired by correcting the detection output level (piezo input envelope waveform) of the piezo pickup in accordance with the acquired distance.
