PROBLEM TO BE SOLVED: To provide an effect imparting device which can reproduce effects of a rotary speaker added to a musical sound more really. SOLUTION: This device is equipped with a frequency modulation part 1 which imposes frequency modulation on an inputted musical sound signal, frequency modulation parts 20 and 21 which input its output and impose frequency modulation as well, amplitude modulation part 206 and 27 which input their output signals and impose amplitude modulation, a modulating signal generation part 30 which generate modulating signals for those modulation parts, and a modulation signal control signal 40 which controls the modulation signal generation part 30; and the modulating signals for the frequency modulation part 1 and frequency modulation parts 20 and 21 are synchronously controlled. |
