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