Thanks for the reply.
I did check the videos and the Manual. My question is whether I can move it from System to a Rig, so I can change the assigned values as I change the rigs. I don't think I can, but I thout I'd give it a try
pedal assignments are always global. The pedal chapter in the reference manual describes how you can use a single pedal for several tasks depending on the currently loaded rig.
You do not need to change any assignments live. If you activated the correct pedal links the rig will determine the function of the pedal.
