What is a good sound recording/mixing program for Mac? I'm looking for something comparable to Acid Pro on PC. My band has been using that for a long time but I'm going to buy the Griffin iMic (I think that's what it is) to get an audio in. I know Soundtrack Pro is great, but I can't afford that.. I'm just looking for something with decent equalizers, some effects (reverb, etc,) and multiple tracks.
