Hey there,
I don’t know about the technical limitations of the unit, but what about being able to use external momentary footswitches connected to EXP1/2 to assign different custom functions like Midi Messages, turn off Blocks, Looper Functions, Switching Modes, etc etc
For example, I would like to use a TRS Cable to a 2-way momentary footswitch to use the basic functions of the looper without having to open the looper UI.
