GENERATOR FOR NON-HARMONIC OVERTONE BY ADDITION SYNTHESIZATION IN MUSICAL INSTRUMENT

摘要

A keyboard operated electronic musical instrument is disclosed which has a number of tone generators which are assigned to actuated keyswitches. Musical tones having an anharmonic overtones structure are produced by generating a number of component waveshapes each having a different fundamental frequency. These component waveshapes are summed to produce a single tone. Each component waveshape has a spectral content of a preselected subset of non-zero harmonic coefficients. The various components have mutually exclusive selection for the non-zero harmonic coefficients.
