Abstract: A method for achieving the effect of air movement in instruments during replication and sounding of complex musical instruments by separating unstable frequency components, the quasi-periodic components, from stable fundamental and harmonic components, the periodic components, of compound voice waveforms, storing the respective component information pertaining to the quasi-periodic and periodic components in separate memory locations, and recombining the quasi-periodic component with one or more periodic components in appropriate fashion to form and sound the compound voice waveforms.

Abstract: The present invention provides an apparatus and method for phase synchronizing tones in an electronic musical instrument. The apparatus includes a microprocessor having an input for receiving a signal representative of a selected note whereupon receipt of the signal, the microprocessor checks a set of available ranks to determine which of the available ranks is associated with the selected note. The apparatus further includes an oscillator which is established for each rank determined to be associated with the selected note such that each oscillator includes initializing parameters and initiating parameters which define the selected note and the associated rank. The apparatus also includes a plurality of tone engines for generating tones.
