I don’t know if it’s possible, but I would like to have the possibility to change the gain value of a capture in the scene mode, when using a midi footswitch like the airstep. I don’t like the way to control the gain only with an expression padel. The capture itself remains the same but with the gain change I could use the scene mode for high gain, crunch and clean.
Map to the expression pedal value using midi CC1.
Set the CC to a static value when pressing the midi instead of from an expression pedal. 0 is heel down, 127 is toe, 64 is midpoint.
should accomplish exactly what you are wanting but it does tie up the expression pedal application for that preset.
