I've been daydreaming of the computer recording world, wondering how much stuff would cost and what to get. If I were to use my computer for recording I'd want to hook up a Mackie 1604VLZ Pro to it, and have 8 ins and 8 outs. I think the 1604 uses RCA in/out, not totally sure, I don't own one. Is there such a sound card and would I have to sell my soul to afford it?
