PROBLEM TO BE SOLVED: To provide technique for a digital signal processor for mixing that is usable for mixer devices having various demanded specifications, and can make it simple to design a circuit board for signal processing of a mixer device using a plurality of DSPs and make it easy to design processing programs that the respective DSP are made to execute. SOLUTION: It is made possible to specify a mode wherein the number of channels and the number of mixing buses are prescribed, and processing for mixing input signals as many as channels corresponding to the specified mode is repeatedly performed to generate signals of the respective mixing buses. For the purpose, the timing of a final step of the mixing processing performed as many times as the number of channels corresponding to the specified mode is detected to output an accumulation result in the final step, and new accumulation is started with a digital sound signal input in a next step.
