Key assigner for an electronic musical instrument having multiple tone channels and priority level value data

摘要

A key assigner for an electronic musical instrument having multiple tone channels for tone signals generated by tone signal generator means controlled by a tone signal generation instruction input device. The key assigner includes a random access memory having an assignment table for storing priority level value data for each of the multiple tone channels for controlling the order in which musical tone signals present in the tone channels are halted when new tone signals are to be generated. An assigner halts the existing tone signal for the tone channel having the lowest priority level value in the assignment table upon the generation of a new tone signal instruction and assigns the new musical tone signal to that tone channel. A control provides priority level value data for storage in the memory in consonance with musical attribute data for the new musical tone, such as sustainment or attenuation of the new tone.
