Abstract
A musical sound synthesizing apparatus synthesizes plural-series overtones having different inharmonicity and amplitude level so as to generate a musical sound close to a natural sound. Inharmonicity coefficients K1 and K2 are read out for each overtone of different series in accordance with a timbre and a pitch, preferably modified according to a touch velocity, and then inputted to the first and second overtone frequency generators 19 and 20. Two series of overtones respectively computed in first and second overtone generators 21 and 22 on the basis of fundamental and overtone frequencies computed using of the coefficients K1 and K2, are controlled in its amplitude by the multipliers 25 and 26, and then synthesized so as to be outputted as a musical sound signal. In the multipliers 25 and 26, respective overtones are multiplied by amplitude coefficients Lk1 and Lk2 determined for each series in accordance with the touch velocity so that their amplitude levels are modified.
