Envelope Parameters
The EVOC 20 PolySynth features an Attack/Release envelope generator used for level
control of the Oscillator section.
 Attack slider: Determines the amount of time that it takes for the oscillators of the
Synthesis section to reach their maximum level.
 Release slider: Determines the amount of time that it takes for the oscillators of the
Synthesis section to reach their minimum level.
Sidechain Analysis Parameters
The parameters in the Sidechain Analysis section control various aspects of the analysis
signal. They require precise control to ensure the best possible intelligibility and
tracking.
Attack
The Attack knob determines how quickly each envelope follower (coupled to each
analysis filter band) reacts to rising signals. Longer Attack times result in a slower
tracking response to transients of the analysis input signal.
Note: A long Attack time on percussive input signals (a spoken word or hi-hat part, for
example) will translate into a less articulate vocoder effect. Set Attack to the lowest
possible value to enhance articulation.
