Overview of the VC-1
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-ENV and 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).
