Example: Compressor (Combination)
Compressor-type effects use the level of the audio
input to control the level gain of the audio output.
For these effects, the envelope detection source can be
either the audio input itself (the usual method) or FX
Control Bus 1 or 2.
Vocoder (Program)
Example: Vocoder (Program)
Vocoder effects produce their distinctive sound by
using an audio signal (the modulator) to modulate a
different audio signal (the carrier). In the diagram, the
output of OSC1 and 2 are the carrier, and the audio
input from a mic is used as the modulator to produce a
"speaking instrument" type of effect. Use Bus Select to
send OSC1 and 2 (the carrier) to IFX1, and set the FX
Control Bus (0–8c) to FX Control 1 for the mic
connected to the AUDIO INPUT, and specify FX
Control 1 as the "Modulator Source" for IFX1: Vocoder.

The example shown in the diagram is of a split
combination in which the level of timbre 1 (Pad,
played from the low key range) is being controlled by
timbre 2 (Guitar, with IFX2 OD/Hi-Gain Wah inserted,
played from the high key range). You can make
settings so that when you play the guitar sound, the
volume of the pad will decrease automatically. Send
the post-IFX2 signal via FX Control Bus to FX Ctrl1,
and set the IFX1: Stereo Compressor "Envelope
Source" parameter to FX Ctrl1.
