It would seem like what the FCB1010 is sending is a simple form of NRPN, sending just one CC # and value per button vs. sending three CC #s per button but I am thinking that the idea is the same.
I think if you can modify the script that @David-san wrote for me in the above thread to the values you are trying to manage into unique CC numbers, you can run a gig-script that converts the FCB1010 into something you can add to the rig manager and map to widgets.
