I'm starting to do audio creation/editing and I've been absolutly in love with Acid Pro on my PC, but now that I've gone pretty much totally Mac I'm at a loss as what software to buy. I've just bought a synthesizer and would like something that can handle midi and well as audio editing, mastering, and loop creating. Here's my problem, I don't want to spend a lot of money. I've been looking around and I want something to start out with and it looks like Emagic's MicroLogic was a good deal but one HUGE no-no, OS 9 only. So my question is, apart from spending $300+ dollars, what are some good software packages to look into?
