I'd Like to be able to assign different midi parameters /rig.
I don't always use the same slots for the same effects on all my rigs. This means I can never label my foot controller. I'd like to be able to keep my floorboard controller assignments the same and change them in the kemper.
This would make it easier to change signal flow in the effects rigs as well as be able to assign the same pedals to different functions / rig.
Also the ability to assign multiple functions the same midi value allowing me to control how ever many functions with the same midi command. I can think of many uses for this not only in pedals, but also for effects (think one switch controls a solo boost AND eq, And switches in reverb/delay)
