EVOC 20 PS synthesis overview in MainStage
EVOC 20 PS is equipped with a polyphonic synthesizer that accepts MIDI note input. Synthesis section parameters are outlined below.

Synthesis parameters
Oscillator parameters: Determine the basic waveforms for the synthesis engine of EVOC 20 PS. See EVOC 20 PS oscillators overview.
Tuning and Pitch parameters: Control the overall tuning of the synthesizer, and aspects such as pitch bend and portamento. See EVOC 20 PS tuning and pitch controls.
Filter parameters: Shape the basic waveforms of the oscillators. See EVOC 20 PS filters.
Envelope parameters: Control the level of the attack and release phases of the synthesizer sound. See EVOC 20 PS envelopes.
Global parameters: Determine the keyboard mode and number of voices used by EVOC 20 PS. (The Global parameters are located at the top left of the interface.) See EVOC 20 PS global parameters.
