Each Partial (Partial 1 and Partial 2) can have one of two sound
generators (a Synthesizer sound source or a PCM sound source), So
you can think of the D-50 having powerful synthesizers built in.
Each of these hypothetical synthesizers could behave like a
conventional analog synthesizer, or a PCM sampled synthesizer. Any
combination of two synthesizers can achieve some remarkable cross
—modulation effects, so characteristic of today's purely digital

sounds.
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.
