PROBLEM TO BE SOLVED: To generate a musical sound near to a natural sound by synthesizing plural series of harmonics with different inharmony and amplitude levels. SOLUTION: Inharmonic coefficients K1, K2 read out according to a tone color and a pitch at every harmonic of different series and corrected by a touch velocity are inputted to first, second harmonic frequency generation parts 19, 20. After the harmonics calculated by first, second harmonic generation parts 21, 22 based on harmonic frequencies calculated using the inharmonic coefficients K1, K2 are amplitude adjusted by multiplication parts 25, 26, are synthesized to be outputted as the musical sound. In the multiplication parts 25, 26, amplitude coefficients Lk1, Lk2 decided at every series according to the touch velocity are multiplied to respective harmonics, and the amplitude levels are revised. |
