PROBLEM TO BE SOLVED: To quickly and uninterruptedly add noiseless sound effect by switching the storage part, which reads an effect signal through the switching operation of a switching part, with the change-over of the sound effect instructed. SOLUTION: The signal, to which an effect is added by multipliers 41A and 41B, is added by an adder 42A, synthesized into a musical sound signal, transmitted to a storage circuit A or B set by a switching part 46 and stored. The effect signal synthesized by an arithmetic part 44 is stored in the storage circuit A, while the musical sound original signal is stored as is in the storage circuit B. Then, with the change-over of the effect instructed, each switch SW1, SW2, SW3 of the switching part 46 is switched, so that the feedback signal is constantly read out from the storage circuit outputting the effect signal, transmitted to the arithmetic part 44, synthesized into the musical sound original signal, and then stored in the storage circuit outputting the effect signal. Consequently, it immediately allows the output of the newly switched musical sound effect. |
