EVOC 20 PS tuning and pitch controls in MainStage
The parameters at the lower left of the interface control the overall tuning and other pitch-related aspects of the EVOC 20 PS sound.

Tuning and pitch parameters
Tune field: Set the overall tuning in cents. One hundred cents equals one semitone step.
Analog knob: Set the amount of random pitch detuning. Analog simulates the instability of analog circuitry found in vintage vocoders by randomly altering the pitch of each note. This behavior is much like that of polyphonic analog synthesizers.
Glide knob: Determine the time it takes for the pitch to slide from one note to another—portamento. Also see EVOC 20 PS global parameters for information about mono and legato mode.
Bend Range field: Determine the pitch bend modulation range, in semitone steps.
