Partial phase - The phase of each partial that plays.Partial amplitude - Amplitude of each partial that plays.This set of partials is scaled in frequency by the fundamental frequency (root note) played. Partial frequency - Frequency of each partial to play.There are three sets of data required to store and manipulate an additive waveform. Inharmonic partials tend to confuse the root note pitch byadd a metallic or noisy edge to the tone. Harmonic partials tend to reinforce the root note pitch adding complexity while maintaining a melodic tone. Partials can be harmonic, an exact (integer) multiple of the base frequency (notes pitch) or inharmonic, decimal multiples ofthe base frequency. Each sine wave is referred to as a 'partial' as it is part of the complete series of sine wavesthat combine to produce the original waveform or sound. In short, French mathematician, Joseph Fourier, showed that any waveform can be decomposedinto a set of sine wave components.
