PURPOSE: A digital signal processing device and a voice and tone synthesizing device are provided to efficiently and quickly perform complex operation process. CONSTITUTION: The first and second buses(PBUS,DBUS) are connected to each of digital signal processors(DSP1-DSP4). Parameters necessary for operations are distributively supplied to the digital signal processors(DSP1-DSP4) via the first bus(DBUS). The operation result of each of the digital signal processors(DSP1-DSP4) is transferred to another digital signal processor or an output port via the second bus(DBUS). One digital signal processor receives output data from another digital signal processor via the second bus(DBUS), and performs a predetermined operation using the received data. The desired sound signal processing is thus executed by combinations of the operations performed by such signal processors. Where sound signal processing is executed in a plurality of channels on a time-divisional basis, the time-divisional channel timing of each digital signal processor is set independently of that of other digital signal processors.
