ADAPTIVE MUSICAL SOUND GENERATION ALLOTTER FOR ELECTRONIC KEYED INSTRUMENT

摘要

A keyboard operated electronic musical instrument is disclosed in which a first set of tone generators is assigned to actuated keyswitches on a first keyboard and a second set of tone generators is nominally assigned to actuated keyswitches on a second keyboard. Assignment logic is provided so that when all the members of the first set of tone generators have been assigned an addition keyswitch actuation causes the temporary borrowing of one of the tone generators in the second set to respond to the newly actuated keyswitch. Saturation of tone generator assignment is diminished by a glissando detect subsystem which inhibits the use of a long release envelope release phase if a glissando has been initiated.
