EVOC 20 PolySynth
15
The EVOC 20 PolySynth combines a vocoder with a polyphonic synthesizer, and can be played in real time. The EVOC 20 PolySynth is a sophisticated vocoder, equipped with a polyphonic synthesizer, and capable of receiving MIDI note input. This allows the EVOC 20 PolySynth to be played, resulting in classic vocoder choir sounds, for example. Single notes and chords played with the polyphonic EVOC 20 PolySynth will sing with the articulation of the analysis audio source. During this process, the sonic characteristics and changes of the audio signal arriving at the analysis input (the audio track selected as a side chain) are imposed onto the output signal of the integrated synthesizer (the Synthesis section). The signal path of the EVOC 20 PolySynth is shown in the block diagram on page 224.
