Extended harmonics in a polyphonic tone synthesizer

摘要

A keyboard operated musical instrument is disclosed in which a musical tone having an extended range of harmonics is produced by combining two waveshapes. The first waveshape has a spectrum containing only the odd-numbered harmonics and the second waveshape spectrum has all the harmonics and is phase locked to the first waveshape. The second waveshape has a fundamental frequency which is twice the fundamental frequency of the first waveshape.
