Abstract
A keyboard operated electronic musical instrument is disclosed in which an independent monophonic tone synthesizer is operated from the same keyboard that controls the generation of tone from a polyphonic tone generation system. The highest frequency note is assigned to the monophonic tone synthesizer and all other actuated keyboard switches are assigned to the polyphonic tone generation system. The detection of the highest note is initiated each time that a keyswitch changes from an unactuated to an actuated state. An alternative arrangement is to assign the lowest frequency note to the monophonic tone synthesizer.
