Okay, first off I am a complete computer novice. I recently acquired both Garageband and the M Audio Fast Track. Now, for some reason, I can NOT get a stereo signal from my guitars. When I set up Real Instrument, it's on Ch1 and 2 Stereo. My Soundsticks work fine the rest of the time. Only the right channel gives any output. When I record in mono on the Ch 2, both speakers work fine. In contrast, when I try Ch 1 mono, no sound comes out. The stereo button on the Fast Track itself is in the right place. What am I overlooking?
