I want to do this on the cheap. I have the current MP3's of old video game music... I would like to remix them and make new music. I currently have a SR MBP, and a M-Audio Oxygen8 v2. Can I use garage band? Do I need to buy a Jam Pack(s)? If not, what software would you recommend? I need something pretty cheap. I already forked out 120$ for the Oxygen 8.... what else do I need? And is there any good starter tutorials out there? Thanks all!
