Hi,
I've had this problem before. I unplugged my Novation Launch Control while Logic was active and now it's stopped responding. The workaround is to tediously reassign all the mapping to the plugins.
Logic shows controller activity in the transport window, but doesn't send this to the mappings I've set up in Controller Assignments - all mappings show up in the Controller Assignment window.
I can reassign new mappings, but not access the ones I've already mapped (16 banks!).
I've tried using Time Machine to revert to the two Logic prefs, no joy.
Am I missing something please?
Thanks,
Alexander
