090: Vocoder
This effect can be assigned only to the D FX processor (usually,
the modulating effect for the Keyboard tracks). When this effect
is selected, the microphone input no longer goes to the Voice
Processor, but is routed to the D FX processor.
When programming the Vocoder, you can use one of the spe-
cially programmed "Vocoder" Performances (in the SFX bank)
as templates.
Before using the Vocoder, you must connect a microphone and,
set the 1/MIC selector to the MIC position.
This effect applies the character of the microphone signal (Mod-
ulator) to the track's oscillator signal input (Carrier). Therefore,
the voice can modulate one of the sounds of the Pa1X. A com-
mon use of this effect is to produce the sound of various instru-
ments 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 a Carrier.

By offsetting the Carrier filter, you can adjust the height of the
frequency range to which the vocoder effect is applied. The tonal
quality will change significantly.
f: Modulator Mix
This parameter sets the high-range output level of the right
channel sound (Modulator). If the modulator is a human voice, it
will make the words more clear.
The "Vocoder/Carrier" parameter sets the balance between the
vocoder sound and the left channel sound (Carrier). The "Wet/
Dry" parameter sets the balance between the effect and dry
sound.
If you wish to change the intensity of the vocoder effect, select
Wet for "Wet/Dry", and adjust the balance using the "Vocoder/
Carrier" parameter.
Note: When you assign the Vocoder effect to the D FX processor, the
direct input can no longer be heard. The input signal goes entirely
to the FX processor. To listen to the direct signal, you can still use
the "Wet/Dry" parameter to increase the level of the direct signal
(Dry).
Please remember to set the tracks Pan value to Off, and the Send
value to 127.
You can add reverb to the Vocoder, by way of the "D to C" parame-
ter.
Hint: To create a new Song making use of the Vocoder, enter the
Sequencer-Backing Sequence mode with a Performance that
includes the Vocoder effect.
