Abstract:
1. A sound generation device comprising: a plurality of sound generation channels that generate sound; an address calculator that calculates an address in order to read, from a waveform memory connected by a bus, waveform data to be assigned to the respective sound generation channels, by time division, for each of the sound generation channels; an address memory that associates and stores addresses calculated by the address calculator and the sound generation channels; a bus traffic detection unit that detects traffic information representing a traffic state of the bus; a waveform data reader that reads an address stored in the address memory, when it is determined that the bus is in a low traffic state based on the detected traffic information of the bus, and reads waveform data from the waveform memory based on said read address; and a waveform generation prescription unit that prescribes assigning waveform data read by the waveform data reader to a corresponding sound generation channel, and generating a sound for the sound generation channel to which said waveform data is assigned.
