PURPOSE:To enable reducing a sound-cutting at the time of changing a parameter by judging whether a parameter changing is associated with the changing of a delay time or not and determining whether a musical sound signal to which an effect is imparted is muted or not. CONSTITUTION:When the parameter changing of a filter 1 is linked to a noise generation, a multiplier B controls only the signal of the filter 1 by making a muliplication coefficient small. When the parameter changing of the filter 1 is not linked to the noise generation, the multiplier B does not control the wet signal and the dry signal of the filter 1. An adder 2 adds a signal made to be the coefficient multiple of the output signal of the filter 1 by the multiplier B and a signal made to be the coefficient multiple of an input signal by a multiplier A. When the parameter changing of a reverb 3 is linked to the noise generation, a multiplier D suppresses the signal of a reverberant sound of the reverb 3. An adder 4 adds the wet signal of the multiplier D and the signal of a multiplier C to make them an output signal. |
