Expression to Volume
The Unity6 now has the ability to use a single expression pedal to control/send MIDI expression messages AND it can be used as a standard volume pedal. This can be saved on a per bank basis meaning one bank it can be a volume pedal and then jump to a different bank and use it an expression pedal to control parameters like Wah, Phaser, Decay Time, Repeats, etc.
Clicking on either checkbox will make the expression pedal as a volume pedal and it will disable the Exp Pedal control for that Bank.
Note: Slight digital artifacts can appear when sweeping Expression to Volume. This is a known limitation of the current hardware — see Why Do I Hear Slight Artifacts With Expression to Volume?.
