Roland VC-1 D-50 owner manual Structure of Tone Parameters, WG Wave Generator

Overview of the VC-1

Structure of Tone Parameters

Depending on which generators are selected in the Partial Block, greatly different Tone Parameters will be used. Some Tone Parameters used for the Synthesizer sound generators are irrelevant to the PCM generator. In a Structure with Ring modulation, some parameters of Partial 2 are automatically set to those of Partial 1.

WG (Wave Generator)

In the WG (Wave Generator), the pitch and waveform are controlled.

Pitch

The basic pitch of a Partial (sound generator) can be set here. The pitch is a Common parameter, and is

therefore controlled by P-ENVand LFO-1.

Waveform, PCM Wave Number

This selects the waveform of the sound source. When a synthesizer sound generator is selected, the

waveform can be controlled by the Pulse Width controls.

Pulse Width

This changes the waveform of the sound source. The pulse width is controlled by any LFO (= Common parameter).
