Reply to Traktor mapping: matching loop size and move size?

Hey all,

I'm working on a super-simple mapping for my MF3D and Faderfox DJ3, and am looking for a way to ensure the loop size and move size for a deck are always the same.

I have increase/decrease for both parameters set to the same control, but the move size parameter has one more "notch" in each direction than the loop size does, so it's easy to get out of sync.

Anyone got any ideas how I could stop the move size going to its extremities? Maybe setting a modifier when the loop size reaches either end? I've been unable to get it done so far.

Any help appreciated. Cheers,
Ibsh
