I have a rack with some pedals and rack gear and I just recently got an All Access because I wanted more instant access to loops on my 2 GCX's. I now find that after programming the All Access, I really can't use it to maually switch all 16 loops. Is it possible to use the GCP and the All Access at the same time? I was going to sell my Ground Control Pro but now am considering keeping it to pull this off.

Guess you can set your All Access to 15 IAs, and send all program changes from the GC Pro (either in 10 presets mode or in 4 presets+8 IAs mode).
Only semi-annoying thing to deal with would be the necessity to save any change to both the GC Pro and the AA.
