Vocoder
The vocoder creates “talking instrument” effects. To use Vocoder, input an instrumental sound into the left
channel and a vocal sound into the right channel. The instrumental sound is split into ten frequency bands to be
processed according to its frequency components.
fig.08-14
Instrumental sounds are input into the L-channel side of the effect. Therefore, it is required to insert and connect
“Lch” of the effect to the channel handling instrumental sounds. Similarly, vocal sounds are input into the
R-channel side of the effect. Insert and connect “Rch” of the effect to the channel handling vocal sounds.
Parameter (full name) Setting Function
Voc (Vocoder): The pitch is specified with the instrumental sound while the tone is output in vocals.
Char 1–10 (Voice Characters) 0–100 Sets the volume by frequency band. These are used to
change the vocoder tone.
CHO (Chorus): Adds spaciousness and depth to the sound.
Sw (Switch) On, Off Turns the chorus on or off.
Rate (Rate) 0.1–10.0 Hz Sets the rate of modulation.
Depth (Depth) 0–100 Sets the depth of modulation.
PreDLY (Pre-Delay) 0–50 ms Sets the time delay from when the direct sound begins until
the processed sound is heard.
FBLvl (Feedback Level) -100–100 Sets the amount of the chorus sound should be returned to
the chorus input.
FX Lvl (Effect Level) -100–100 Sets the volume of the chorus sound.
DirLvl (Direct Level) -100–100 Sets the volume of the direct sound.

Tips for using Vocoder
It is a good idea to choose instrumental sounds containing a lot of overtones. Recommended sounds include those
with saw-tooth waveforms such as strings and distorted guitar sounds.
