USB Interface

ah that looks like it'd do the job, i'm basically after something to go with a macbook pro so i can record vocals and mic up amps and stuff, just something that would be better than using the mac's own soundcard
 
M-Audio's gear is usually amongst the best in each of the various price barriers for budget and semi-pro gear. I've bought a few of their soundcards over the years and have never thought that I hadn't got what I'd paid for....good luck!
