I know this was posted a few weeks ago, but I can offer a suggestion - I noticed that
lynda.com has a training program for Soundtrack Pro 2. I have never seen it, but I remember looking at some of their other material and it was pretty good at getting one through the mechanics of how to use a given software program.
I just had another look at lynda.com and I see they have 7 hours of essential training and 4 hours on filters for Soundtrack Pro 2. One puzzling thing - the essential training videos for Soundtrack are closed captioned - I am wondering how a deaf person could learn to edit and mix audio! If they can do it with Soundtrack Pro, then it has to be more amazing than I already think it is!
