Vocoder Functions
Vocoder is a process of using real-time frequency spectrum of one sound
(Modulator) to modulate the frequency spectrum of another (Carrier).
it contains a series of bandpass filters that allow through only those
frequencies detected in the Modulator source. For example, when a
human voice is used to modulate a synthesizer voice, it will sound like
the synthesizer is talking, very interesting effects.
Selecting Vocoder Types
Set the Module Selector to [VOCODER] to enter Vocoder module, you
can select vocoder types by pressing [VALUE] button. There are 3 types
o
f vocoder effects in VEM Box: Vocoder, Robot, Whisper.
Vocoder is a standard classical vocoder, you need to plug an instrument
into the INST. IN jack as a carrier source, and connect your microphone
to [MIC IN] jack, then play the instrument while speaking or singing, you
will enjoy the wonder sound.
Robot is a traditional vocoder effect often heard from many sci-fi movies,
to use this vocoder effect, just plug your mic and speak or sing.
Whisper is an alternative vocoder effect which can makes your voice
sound like devil speaking, to use this vocoder effect, just plug your mic
Adjusting Vocoder Effects
Each vocoder effect has the same parameter (Gender) to adjust, use
[VALUE] knob to change parameter range ( ~ ), gender can slew the
p
itch of the vocoder down for a more masculine sound (smaller value) or
up for a more feminine sound (bigger value).
Note: When Vocoder module is working, other effects module will be invalid,
but the parameters of them will be unchanged.
Note: When saving a patch with active vocoder effects, other module’s
parameter can be stored as well whereas they are invalid. When vocoder is set
to off in this patch, other effects modules will return to their corresponding
state.
