PURPOSE:To control harmonic degrees of respective frequency components of a musical sound by changing control values of respective frequencies of respective frequency components of a formant shape signal. CONSTITUTION:In the frequency formant harmonic degree data Hfj(t) of a frequency inharmonic table 93, a value corresponding to a format carrier parameter omegacj(t) is read out to be weighted by total format harmonic degree data Hwj(t) with a multiplier 94 and added and synthesized to frequency number data FN with an adder 92 and then outputted as a frequency density parameter omegafj(t). Then, a harmonic degree (a density) determined by the parameter omegafj(t) is controlled and controls are performed to plural formant carrier parameters omegacj(t) and at every formant. Moreover, frequency number data FN are multiplied by sampling correcting data Sfj(t) with a multiplier 91 to be corrected and then a correction corresponding to the difference of the storage sampling frequency of a formant shape signal Ffj(t) is performed. |
