Hi! Just wanted to bug you all about M-Audio Fast Track Pro. 4x4 USB interface. Professional quality box. (Or is it?) If there's anyone who owns such an interface, please write some small review just to get me and other possible buyers informed... Is it OK? Does it possibly have problems with latency? How are the pre's? Should I just skip this and spend some more money to buy Presonus Firebox for example? Thanks in advance!!
