I just recently acquired the MC6 and the first thing that I would like to get squared away with it is PC scrolling on my Big Sky and Timeline. After following the set up instructions for this message as posted in the manual and blog, I initially had it working perfectly. Scroll up went through my presets 1 at time on each device, scroll down did vice versa. However, within minutes the scrolling becomes very randomized flipping from my bank 01A to 45B. I have not found a rhyme or reason to what I am doing that is causing this change in the scroll, but I would appreciated any suggestions about correcting it!
