Okay, so to clarify: you can in fact select parameters across multiple pedals, the problem is that you want 1 “pedal” (I’m assuming you mean an expression pedal vs a footswitch) to control multiple parameters.
So ideally you want to say, be able to select a parameter somehow, and then the the means to control those parameters would be assigned to the expression pedals on your footswitch?
If this assumption is correct, the problem isn’t a modep one, your pedal will only be able to send one midi cc message at a time and what channel that is, whether its a note or CC, and whether it’s momentary or a hold depends on the controller. I know my controller has its own software that I use to assign these things.
As far as “selecting any midi channel goes” and a learn function, can you be more specific? As far as I can tell modep doesn’t have any midi channels that cant be used, and again, if you want to change what message your pedal is sending you do at via your controller, not modep.
What pedal are you using?
