OUTLINE OF TONE PARAMETERS
(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.
A "Synthesizer sound generator” works like a conventional analog
type synthesizer with an oscillator, a filter, an amplifier and two
ENV's. A PCM sound generator provides 100 different PCM sampled
sounds.
These two Partial sounds (Partial 1 and Partial 2) can simply be
mixed as shown below.

Partial 2 IP
By mixing two Partials, fatter sounds can be obtained. This is
effective for making strings or organ type sounds,
Or Partial 1 can be mixed with the ring—modulated sound of
Partials 1 and 2,
