	Structure

Structure, which is one of the Common Parameters, determines which two of the hypothetical synthesizers (a synthesizer sound generator or a PCM sound generator) are to be used as Partial 1 and Partial 2.

•These two Partial sounds (Partial 1 and Partial 2) can simply be mixed as show below. By mixing two Partials, fatter sounds can be obtained. This is effective for making strings or organ type sounds.

•Partial 1 can be mixed with the ring-modulated sound of Partials 1 and 2. (“Ring Modulator” (p. 40))

A Tone consists of two Partials (Partials 1 and 2) and a Common block. Some Common parameters apply to both Partials (Partial 1 and 2) . “Structure” is one of the Common parameters. It decides which of the two sound generators is used for each Partial. Other Common parameters are an ENV for pitch, three LFO modules, equalizer, chorus, etc.
