Hi. I've been trying to solve this problem for two weeks, maybe someone can help. Just got off the phone with AppleCare, who were pretty useless---they want $49 to help me fix a piece of software that costs half that. Thanks, Apple.
I am running Garageband '11 through an M-Audio Fast track unit into an iMac OSX 10.6.8.
Two weeks ago, the amps in GB stopped working. All I hear is the sound of a clean electric guitar no matter what amp I choose.
The bizzarre thing is on every song I recorded before two weeks ago, if I go into the file, the amps all work.
But every time I create a new song now, the amps do not work, nor do I see a signal to tune my guitar through GB.
Anyone---anything - please - I have gigs and need to make demos for my musicians.
