Overview of the VC-1

The Basic Concept of a Tone

Throughout the process of programming the D-50, the operation remains simple and logical.

You can think of the D-50 having powerful synthesizers built in. Each of these hypothetical synthesizers could behave like a convention analog synthesizer, or a PCM sampled synthesizer. Any combination of two synthesizers can achieve some remarkable cross-modulation effects.

Partial

The VC-1 (D-50) appears to have four powerful synthesizers built in. Each of these hypothetical synthesizer could behave like a conventional analog synthesizer, or a PCM sampled synthesizer. Consequently, They are referred to as Partials, since they are far more than just a pure synthesizer. These Partials are combined in pairs to form a TONE, A Tone could either be a mix of the two Partials, or they could take advantage of the LA version of cross modulation.

Synthesizer sound generator

A Synthesizer sound generator works like a conventional analog type synthesizer with an oscillator, a filter, an amplifier and two ENV’s.
