PURPOSE:To obtain the near real expressing force of wind instrument performance, to prevent parasitic oscillation and further prevent a signal from overflowing, and to synthesize a musical sound signal with an added inharmonic spectrum component which can not be generated only by a tube body. CONSTITUTION:An oral cavity glottis forming circuit 10 simulates the shapes of an oral cavity and a glottis. Further, a junction JCT 1 cascades the oral cavity glottis forming circuit 10 and an excitation element simulating circuit 11. The excitation element simulating circuit 11 simulates the reed and tongue of a wind instrument. Further, a junction JCT 2 cascades the excitation element simulating circuit 11 and a tube body forming circuit 12. The tube body forming circuit 12 simulates the tube body of the wind instrument. In this circuit constitution, one of paths for the cross connection of the junction JCT 1 is omitted. |
