Abstract
A plurality of sound source apparatuses are mutually connected so as to function as if they are a single sound source apparatus. The number of polyphonic channels is increased in accordance with the number of sound source apparatuses connected. In connecting these apparatuses, it is necessary to designate a polyphonic channel region in use for each sound source apparatus. The region may be set by specifying the upper and lower limits of polyphonic channels of setting a machine number of each sound source appartaus. Alternatively, the region may be automatically set.
