PURPOSE:To realize an effect sound with slow changing speed without increasing the length of coefficient word of signal processing without complicating the operation of a controller by providing a control signal output terminal capable of outputting a signal subject to prescribed processing in a control data format in addition to a signal input/output terminal and a control signal input terminal. CONSTITUTION:A 2nd signal processor 6, based on information fed from a controller 8 via a control signal input terminal 7, outputs a coefficient (e.g., data of sound volume) required for the processing by a 1st signal processor 3 to the 1st signal processing unit through a control signal output terminal 5 and a control signal input terminal 4. The signal processor 3 uses the coefficient received in this way to process the signal inputted from the signal input terminal 1 and outputs a signal to be processed to a signal output terminal. In this case, as the sampling frequency for the 2nd signal processor 6, a low frequency to cope with a change in the effect sound is selected. Thus, an effect sound with slow changing speed is realized. |
