Claim:
A sound generation assignment device comprising: a plurality of sound generation channels to which any of a plurality of generators of a sound source connected thereto is assigned when a sound generation instruction is supplied; a plurality of input ports to each of which an application of music sound generation is set, and a sound generation instruction from outside is input; priority setting means for setting a priority to said each port; maximum channel number setting means for setting the maximum number of sound generation channels assignable to said each port; and channel adjusting means for, in the case where, when there is a new sound generation instruction input to an arbitrary port, there are sound generation channels to which generators are not assigned in the maximum number of sound generation channels belonging to the arbitrary port, assigning the generators corresponding to the sound generation instruction to the sound generation channels to which generators are not assigned; and when generators are assigned to all the sound generation channels, assigning the generators corresponding to the sound generation instruction to the sound generation channels to which generators are not assigned, the sound generation channels belonging to another port to which an application of the same priority as that of the arbitrary port by the priority setting means.
