ABSTRACT:
An electronic musical instrument of a channel assignment type wherein depressed keys from among a larger plurality of keys are respectively assigned to a smaller plurality of tone producing channels for generating wave of musical tones. The assigner comprises a microprogram, an arithmetic section, a memory, and an interruption control circuit to assign the depressed keys to available tone producing channels. The current on-off information of the keys is subjected to calculation to form a key-on request file and a key-off request file. A tone request file is formed on a plurality of tone data as designated by the tone levers. A channel assignment table is formed, based on the key-on and key-off request files, to indicate a status of assigning the depressed keys to the tone producing channels. The channel assignment table is stored in the memory and the contents thereof are supplied to the wave generator, whereby a plurality of musical tones are generated simultaneously by the wave generator as controlled by the microprogram.
