I've started using more outboard gear in mixing, which for me means sending a digital signal out of Logic from the Metric Halo ULN2, via AES to a Lavryblue MDA 824, through analog gear, back into the MAD-824, then through the AES input of the ULN2 into logic.

The problem I ran into was latency -- audio I processed in this fashion would show up in logic late.

The fix I've found so far is to, by trial and error, to adjust the "record delay" parameter in logic (under preferences --> drivers --> recording delay)  to a value of -70 .... which as I understand it moves forward any recorded audio by 70 samples.

So therefore the latency of this system -- the metric halo ULN2, and the lavry MDA 824 out and MAD 824 in, when all added together, seems to be about 70 samples for me.  (recording at 44.1 / 24 bit)

If anyone sees some stupidity here or has a better way of setting this all up, please do let me know -- I thought I would share my simple solution however.

I understand your concern...you want to use a great converter but don't get ADC when you do.  But dont forget that 70 samples is only .0015 seconds, so it's not a horrible thing, unless you are running the same signal ITB and through outboard gear at the same time.  I guess it's just trial and error from what I can tell you as well.

one more thing: many old effects boxes did the same thing, just didn't tell you.  it lead to phasing when a signal was split, due to their latency while the signal was processed.  sometimes a millisecond or less.
