I'm having exactly the same issues. I use the MIDI Control Center and all went fine per your instructions (thanks!), but still, Logic no longer recognizes the modwheel! I use it everyday, and the wheel works everywhere else. And just in case you were wondering, nothing is set to be filtered in Logic. This just happened out of the blue. I need some help here, or I'll have to go out and buy another controller, due to a scoring gig I'm on (no time).
