PURPOSE:To synthesize percussion sound with so much variety as the percussion of natural musical instuments, when played. CONSTITUTION:A play operational panel 32, a pressure detecting elements 33a-33d which are provided on a specified position of the play operational panel 32 with a specified spacing and output the signal corresponding to hitting operation against the play operation panel 32, a resonance circuit part consisting of a bi-directional transfer circuit 20 and a junction 23, a delay time quantity control circuit which detects hit position based on the output signal from the pressure detecting elements 33a-33d and, responsing to the detected position, calculates the delay time quantity of the bi-directional transfer circuit 20 and a exciter means which inputs the excitation signal corresponding to the output signal of the pressure detecting elements 33a-33d into the resonance circuit part are provided. |
