The knobs for my Mid's and high's are stuck in the extreme right and left positions as you can see from the screen shot. It's only happening on the C channel and I've tried everything I can think of. I've run the calibration numerous times, I had custom mappings and a midi fighter twister which I removed and restored all the settings back to the factory defaults. I've tried a fresh install of the software all together, but still stuck like this and it is a problem as I use all 4 decks when I play. Help me Obi-Wan Kenobi, you're my only hope.
