666| Effects for the Sounds
Vocoder
This effect applies the timbral character of a different signal (the modulator)
to the input signal (the carrier).
A common use of this effect is to produce the sound of various instruments
by inputting a voice to the Modulator via a microphone. A special effect is
also achieved by using rhythm or effect sounds. Strings or distortion guitar
sounds with a lot of harmonics are suitable as Carrier signals.
When this effect is selected, the microphone input no longer goes to the
Voice Processor, but is routed to this FX processor.
