Warning! Blatantly obvious ignorance follows!
I was interested in firewire as a way to possibly use a notebook without the 2-channel limitation of USB, but I also like the idea of an external unit anyway. Here's the part where I really show my ignorance: I was under the impression that you had to use the MOTU stuff with Digital Performer, which is a Mac only product. Is this not true? Am I operating under a false assumtion?
