Hi there, Has anyone any experience with the M-Audio Quattro? I'm interested in doing some simultaneous multi-tracking with some extra hardware and this product stood out! I'd of course love a MOTU 828 firewire but hey....we can all dream! So, is this Quattro any good? I have had problems with USB audio before, latency and such when recording a second track after the first, that they are out of time etc etc. so I'm not sure I should bother? Thanks people, Alex
