Abstract
An electronic material instrument includes a tone generator for synthesizing tones by using a number of time-division multiplexed (TDM) modules, an input unit for programming a connection configuration (tone synthesis algorithm) for the modules of each module pair, and a processing unit for converting the input program into control data for each module and transferring the control data to the tone generator. In one embodiment, each module pair is selectively operative in an addition mode, a phase mode or a ring modulation mode, independently of the modes selected for the other module pairs. It is thus possible to attain a tone synthesis desired by the user, and to make the best use of the capacity of the tone generator.
