Thanks for getting back to me so quickly. All I do is sound effect editing for film (video). No live recording. What I need is an audio interface that has 6 outputs and play nicely with ProTools. I don'd believe the new MacPros have firewire but do have USB so my guess is that's what I am looking for - perhaps USB 3.0. I don't currently have Thunderbolt but will in the future but any unit with Thunderbolt would also need USB.
