Greetings - I'm new to Logic Pro (9) after working with Digital Performer and ProTools - both in limited ways - I'm not an engineer. Logic and my 4-track interface are working well together except for this one issue. It may be that the pre isn't powerful enough on the Fast Track. I have to crank it to the equivalent of 8 or 9 (out of 10) to get a decent audio signal with a mic or guitar (Sure SM56, Fender Telecaster). MacBook Pro, 15-inch, Mid 2009 M-Audio Fast Track Ultra (4-track) USB MIDI/Audio Interface Thanks in advance for any suggestions.
