The EVOC 20 PolySynth combines a vocoder with a polyphonic synthesizer and can be
played in real time.
The EVOC 20 PolySynth can create classic vocoder sounds, made famous by artists such
as Kraftwerk during the 1970s and 1980s. Vocoding remains popular in current electronic,
hip-hop, R & B, and other music styles.
The 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 will
sing” 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.
The EVOC 20 PolySynth offers more than vocoding, however. You can use it as a
synthesizer, or for more subtle effects processing—such as the creation of (somewhat)
natural sounding vocal harmonies from a solo voice performance. If your musical tastes
are more extreme, feel free to try processing other audio material, such as drum or
instrument loops.
