EVOC 20 PolySynth and vocoding
EVOC 20 PolySynth overview
EVOC 20 PolySynth combines a vocoder with a polyphonic synthesizer and can be played in
real time.
It can create classic vocoder sounds, made famous by groups such as Kraftwerk during the 1970s
and 1980s. Vocoding remains popular in current electronic, hip-hop, R & B, and other music styles.
EVOC 20 PolySynth “listens” to an incoming audio signal—typically of a spoken or sung
performance—and imposes the sonic characteristics and level changes of this signal onto the
integrated synthesizer.
When you play notes and chords with your MIDI keyboard, the internal synthesizer “sings at the
pitches of incoming MIDI notes, but with the articulations—level changes, vowel and consonant
sounds—of the incoming audio signal. This results in the classic “singing robot or “synthetic
voice sounds that vocoders are mainly known for.
EVOC 20 PolySynth can also be used as a synthesizer, or it can be used for more subtle eects
processing—such as the creation of relatively natural-sounding vocal harmonies from a solo
voice performance. Not limited to vocal processing, you can also achieve interesting results by
processing other audio material, such as drum or instrument loops.
To use EVOC 20 PolySynth, you need to insert it into the Instrument slot of an instrument
channel strip. You also need to provide an audio signal as the analysis audio source, via a side
chain.
Set up EVOC 20 PolySynth in your host application
1 Insert EVOC 20 PolySynth into the Instrument slot of an instrument channel strip.
2 Choose an input source from the Side Chain pop-up menu in the plug-in header. This can be an
audio track, live input, or bus, depending on the host application.
The EVOC 20 PolySynth is now ready to accept incoming MIDI data and has been assigned to an
input, audio track, or bus—via a side chain.
3 If applicable to your host application and needs, mute the audio track serving as the side-chain
input, start playback, and play your MIDI keyboard.
4 Adjust the volume levels of EVOC 20 PolySynth and the side-chain source—if not muted—to
meet your needs.
5 To further enhance the sound, adjust the knobs, sliders, and other controls, and insert other
eect plug-ins.
