PROBLEM TO BE SOLVED: To generate a musical sound having inharmoniousness according to a pitch, a tone color and a touch, etc., without enlarging memory capacity by providing a harmonic frequency generation means operating respective harmonic frequencies and a harmonic generation means, etc., generating the musical sound, based on respective harmonic frequencies. SOLUTION: Inharmonic tables 13-1, 13-2,... 13-N at every tone color are stored in an inharmonic table group 13 as an inharmonic coefficient generation means. A corresponding relation between an inharmonic coefficient K and a key board number, that is, pitch information is set in the inharmonic tables 13-1 to 13-N. Then, the inharmonic coefficient K is multiplied by an inharmonic touch coefficient k in a multiplication part 16, and an inharmonic coefficient K' corrected according to a touch velocity is obtained to the inputted to a harmonic frequency generation part 17. The harmonic frequency generation part 17 operates the frequencies of respective harmonics based on the basic frequency and the inharmonic coefficient K' of the musical sound to be generated to send out to a harmonic generation part 18. The harmonic generation part 18 generates the harmonic of the inputted frequency. |
