Electronic musical instrument having channel controller preferentially assigning sound generating channels to resonant sound signals with large magnitude

摘要

An electronic keyboard musical instrument includes a plurality of sound generating channels selectively assigned to pairs of fundamental sound signals and pairs of resonant sound signals, and a channel controller assigns the sound generating channels to a new pair of resonant sound signals after release of sound generating channels from the assignment to a pair of resonant sound signals for a stereophonic sound with the minimum loudness when the sound generating channels have already assigned to the predetermined pairs of resonant sound signals so as to concurrently produce a large number of stereophonic sounds.
