Hi I'm a little confused about what I need to set up my studio. I've had little experiences with it but have played around at a couple other studios. Right now I have a casio keyboard with a midi out and a electric guitar. I'm about to purchase a Roland MV-8000 from a pawn shop for $600 also my parents are about to buy me a new imac and hopefully I'll get Logic with it. I do intend on studying music producing at school via what in Australia is called VCE which is more a less a small course in producing. I hope to in the future get a mic of some description and possibly a new piano. Do I need a interface and a mixer if so what do you recommend for each under $150 I was thinking of getting a M-Audio Fast Track Pro off some one on Ebay for interface if I need it and Yamaha MG102C for a mixer if needed. At the end of the day I have limited money and I don't want top of the line equipment I just want it to work and be able to learn and eventually if I take a lot of interest in it upgrade.
