Abstract
An electronic musical instrument includes a plurality of tone generating substrates, a connection portion, a channel detector and a channel assigner. Each of the plurality of tone generating substrates has at least one tone generation channel which generates a tone signal in response to assignment information input thereto. The connection portion has a plurality of connection slots with which the tone generating substrates are connected. The channel detector detects a number of all the tone generation channels of the tone generating substrates connected with the connection portion. The channel assigner, responsive to performance information input thereto, assigns the performance information as assignment information to one of the tone generation channels detected by the channel detector. The assigned tone generation channel generates a tone signal in accordance with the performance information.
