sorry to be blatetly abusing this forum for personal gain, but the wealth of knowledge seems so abundant its like the first thanksgiving for me... any comments on the new breed of usb interfaces? more specifically i was looking into the m-audio omni as my front end and the quattro for midi and usb. their website said it was "professional quality audio". hmmmm.... what are the drawbacks if any of usb. can it handle midi and "professional quality" audio...?
