PURPOSE:To synthesize a musical sound faithful to the harmonic structure of an actual wind instrument sound by suppressing the resonating operation of the two-way signal transmission line from an exciting means which generates an exciting signal according to an input signal and the feedback signal from a resonance circuit to a terminal processing means which controls an attenuation coefficient. CONSTITUTION:A signal scatter junction 20 which is interposed and connected between stages corresponding to sound holes of a resonance pipe and performs specific arithmetic processing for each input signal supplied to itself to output the resulting signal to a two-way signal processing means, and the resonance circuit 30 attenuates the output signal of the two-way signal processing means and supplies it to the two-way signal processing means. further, the exciting means 10 inputs the exciting signal to the resonance circuit according to the input signal and the feedback signal from the resonance circuit and the terminal processing control means 100 controls the attenuation coefficient of the terminal processing means TRM corresponding to the opening/ closing operating of the sound holes. Consequently, the musical sound which is faithful to the spectrum of the actual wind instrument sound can be generated. |
