Reference
As another example, let's say that the Unison Detune is still set to 24, but Voices is
set to 4:
Voice one will still be detuned down by 12 cents, voice two will be detuned down
by 4 cents, voice three will be detuned up by 4 cents, and voice 4 will be detuned up
by 12 cents.
Effects
Programs store settings for the Mixer Channel Insert Effects. If the channel's Auto-
Load FX parameter is enabled, then these Effects will be loaded automatically.
To select, edit, or delete Insert Effects for a Program, use the mixer channel. After
the Insert Effects have been edited, they can be saved with the Program using the
File Menu's "Save Program and Effects As..." command. This command is only
shown when the Program Edit window is in the foreground.
