Pick up ACID, it seems like a program devoted to audio mixdowns while also including other functions (midi etc.) And on the topic of making mixes, ive been using cubase sx and is there any way to import mp3s onto an audio track? Cause before i was converting songs to wav files and i dont really have any space for numerous wav tracks on my hard drive. I guess I need some external storage for my ibook, any suggestions for this dilemma?
