PROBLEM TO BE SOLVED: To provide a musical sound modulator for performing modulation in accordance with modulation contents and automatic modulation in predetermined modulation contents to musical sound in response to operation to an input device for inputting the modulation contents by displacing an operator.;SOLUTION: An A/D converter 2 outputs a displacement amount from a home position of a bender wheel 1 in a digital value. CPU 8 instructs the musical sound of note assigned to keys pushing the keys on a keyboard 3 to a sound source LSI9, and instructs the modulation in response to the displacement amount to the sound source LSI9. When changes occur with variation fully satisfying predetermined conditions on the displacement amount, the modulation by cricket play method simulation waveform data stored to ROM 6 as a user separates the wheel 1 is instructed to the sound source LSI9. Consequently, simulation of a cricket play method is enabled without operating the wheel 1.;COPYRIGHT: (C)2006,JPO&NCIPI
