Hi all. I use the MFC mk3 as a midi controller exclusively. Is it possible to send a CC# and value instead of a program change when you change presets using the "Up" and "Down" buttons? The amp I'm using does not use PC messages and I'd like to use the "Up" and "Down" buttons to change settings on the amp (Line 6 DT25). I'd like the CC# to be 91 and the values (one for each model available in the amp) to be 0-30.
