Oh. Lord! Prepare to bash you head against walls repeatedly. My roomate got one of these and we spent forever trying to figure out how to get it working.
I'm pretty sure you can't set this thing up in the Control Surfaces preference.
We found an environment (on Behringer's website I think) that we based an aoutoload around. It was buggy as hell! The play button didn't work but the stop button sure did, and and the BCF's fader's would sometimes skip tracks.
I eventually had to do a system restore and reinstall Logic (for other reasons). I opened Logic for the first time and VOILA: It worked. Perfectly. No BCF environment, no Control Surface Setup, nothing. I still don't know how it worked, but I'm definitely not messing with a good thing.
I wish you much luck on this particular endeavour.
