re:thinking is over rated.
Nonetheless, I'm kind of thinking out loud here.
A Pre-fade send should divert the signal before it is subject the the D/A converter, therby short-circuiting the latency from that. However the round trip would probably introduce some latency, I'm thinking in the 1ms or less range.
Doc, let us know what you find out.
CJ, I would be very tempted to hook it up. My guess is that a very tiny nudge might be all that is required, if that. My guess is that it would be so close that you would be dealing with phasing, and not a blatent latency problem.
There is no shame at the end of the universe. Just a restaurant. Get a good seat.
