Logic Pro 9 C3 only works some of the time- midi problem?


New Member
hey everybody, i'm new to logic so please bear with me. a few days ago the C3 key on my midi controller stopped working. all the other notes work fine. i switched keyboards and reset midi devices but neither worked. i then opened up garageband and assigned a software instrument. everything, including C3 worked fine, making me believe it is not my keyboard but a problem in logic. any help would be appreciated.
