The Basic Concept Of A Tone - Roland V-Card VC-1 D-50 Owner's Manual

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.

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.
