ABSTRACT:
The musical tone synthesizing apparatus synthesizes a musical tone signal in response to the wind instrument and the like to thereby simulate a resonance tube providing with several sound holes each opened or closed by each finger of a performer. Herein, the input signal is delayed by the predetermined delay time, and then the predetermined operational process corresponding to the signal-scattering operation is carried out on the delayed signal. The coefficient used in this operational process is varied in response to the open/close state of each sound hole. Thus, the operation result can simulate the musical tone to be sounded from the resonance tube of the wind instrument and the like.
