Table Of Contents
Wave 1 and Wave 2 fields: Vertically drag the numerical value beside the Wave 1 and
Wave 2 labels to select the waveform type for Oscillators 1 and 2, respectively. The
EVOC 20 PolySynth features 50 single-cycle digital waveforms with different sonic
characteristics.
Dual Mode EVOC 20 PolySynth Oscillator Parameters
In Dual mode, each oscillator can use any of 50 digital waveforms.
Semi and Detune
parameters are shown in
Dual mode.
Balance slider
Semi field: Adjusts the tuning of Oscillator 2 in semitone steps.
Detune field: Fine-tunes both oscillators in cents. 100 cents equals a semitone step.
Balance slider: Sets the level balance between the two oscillator signals.
FM Mode EVOC 20 PolySynth Oscillator Parameters
When in FM mode, Oscillator 1 generates a sine wave. The Wave 1 parameter has no
effect in this mode.
FM Int slider
Coarse and fine Ratio
parameters are shown in
FM mode.
“Ratio c(oarse)” field: Adjusts the frequency ratio between Oscillator 2 and Oscillator 1
in semitone steps.
“Ratio f(ine)” field: Adjusts the frequency ratio between Oscillator 2 and Oscillator 1 in
cents.
FM Int slider: Determines the intensity of modulation. Higher values result in a more
complex waveform with more overtones.
