PROBLEM TO BE SOLVED: To realize a device capable of providing rich musical expressing power or play effect without causing a sounding delay. SOLUTION: A damped oscillation model formed of a spring SP having one fixed end, a weight M installed to the other end of the spring SP, and a damper DP for absorbing the vibration of the weight M is excited according to an input waveform to generate a damped oscillation, and this is used as output waveform. Thus, the output waveform of a frequency component never present in an original sound can be continuously generated without sounding delay, and the nuance in change of the input waveform can be imparted to the output waveform. |
