i was wondering if there are any differences between the delta 44, 66, and the 1010 other than the obvious number of inputs and outputs. i was also wondering what a wordclock i/o is....
You are cross-posting this question, which is not a good thing.
That said, I think in the other forum (Computer Recording and Soundcards) you asked this in, you didn't have the part about word clock.
Word clock is a digital synchronizing signal that can be used so that disparatae pieces of high-end digital audio gear all share the same timing reference.
