I'd like to get at least 4 inputs, preferably 6 or 8. I'm looking at the Tascam US1800, or the US800. Do either one of those work with well with Sonar? Again, I'm new at this so thanks for all the info you can provide. :)
FWIW, I'd avoid Tascam USB audio interfaces.
Very high round-trip latency...
I'd point you to the new Audiobox VSL interfaces from Presonus.
Great features for the price... and low round-trip latency.
