I think I'm getting there … It probably does not do what you want. The presets always load in an active state. You can then send PCs to give you BYP/ACT/TOG. These are here because a number of pedalboards only send MIDI Program Change, and do not send MIDI CC, which one would normally use to change these things.

What you want is that the first time a PC for a given number is sent it loads the program, and thereafter toggles between BYP and ACT. It does not do this. Sorry.

It might be fairly confusing if it did – many users would never be sure if it should load the preset, reload it, bypass it, or what.

MIDImap is not the issue here – these are just use to translate between PC numbers and the 'Factor's preset numbers, and the odd extra function like BYP/ACT/TOG.
