PURPOSE: To provide a musical sound synthesizer capable of realizing a tone change peculiar to a flute system wind instrument. CONSTITUTION: This synthesizer is provided with a drive data generation circuit 101, first and second comb filters (108, 109) circulating the drive data by the circuit constituting a delay device in a closed loop shape and taking out the circulating data as the wavefrom data S1, S2, a mixing circuit 106 mixing the wavefrom data S1, S2 and generating the required synthesis data and a mixing ratio control circuit 107, and by controlling the mixing ratio of the S2 equivalent to the even-th harmonic component of the synthesis data by the control circuit 107, the tone change according to an angle breathing into a tube peculiar to the flute system is realized. |
