EVOC 20 PS global parameters in MainStage
The global parameters at the top left of the interface determine the keyboard mode and number of voices used by EVOC 20 PS.
Global parameters
Poly/Mono/Legato buttons: Determine the keyboard mode.
When Poly is on, you can set the maximum number of voices in the Voices field. (When Mono or Legato is on, a single voice is heard.)
When Mono is on, Glide is always active and the envelopes are retriggered by every note played (multi trigger behavior).
When Legato is on, Glide is active only on tied notes. Envelopes are not retriggered when tied notes are played (single trigger behavior). See EVOC 20 PS tuning and pitch controls.
Voices field: Set the maximum number of voices in the numeric field (only when Poly is turned on).
Unison button: Turn Unison mode on or off.
In Unison/Poly mode—where both the Unison and Poly buttons are active—each voice is doubled. This cuts polyphony in half (to a maximum of eight voices, shown in the Voices field). The doubled voices are detuned by the amount defined with the Analog knob.
In Unison/Mono mode—where both the Unison and Mono or Legato buttons are active—up to 16 voices can be stacked and played monophonically. The Voices field displays the number of stacked voices that are heard.
Important: Stacking voices in Unison/Mono mode increases the output volume. To avoid overloading the instrument channel strip output, set a low Level slider value and gradually increase it. See EVOC 20 PS output parameters.
