> Off:
The vocoder is disabled.
> Osc:
The output of the oscillators, including noise and ring mod, provides the signal for the
carrier.
> Osc Hold:
The same as Osc mode, but with key latch.
> Noise:
The output of the noise generator is used for the carrier signal.
> Input:
The audio inputs provide the signal for the carrier. This means that the same signal is
used for both carrier and modulator, which can result in some very interesting effects.
> CENTER FREQ
Determines the central frequency of the bandpass filters in the modulator and carrier banks.
> MOD OFFSET
Use this to offset the center frequency of the modulator bank relative to the carrier bank.
> MOD Q
Determines the width of the gap between the bandpass filters in the modulator bank. This is
unlikely to have more than a very subtle effect on the sound.
> MOD SPREAD
Determines the spread of the bandpass filters in the modulator bank. Lower values mean a
narrower spectrum of the modulator signal is applied to the carrier signal. A value of +63
means that the whole frequency spectrum of the modulator signal is applied to the carrier
signal.
> CARR Q
Determines the resonance or quality of the filters bands in the carrier bank. Lower values will
result in a fairly neutral tone, whereas higher values result in a more artificial sound.
> LINK
With Link enabled, Carr Q and Mod Q are adjusted simultaneously, as are Mod Spread and
Carr Spread.
