I have yet to hear ANY current DAW that does outboard hardware latency compensation down to the sample. Cubase/Nuendo have a "ping" feature that approximates
the amount of latency introduced by the round-trip. However it is NOT sample accurate compensation and will introduce some
latency. Usually, the latency is minute and is not terribly noticeable, but it's there (you can hear it when doing parallel compression). What Cubase and Logic (using the latency fixer plugin) do is essentially the same thing.
Don't believe me? Try this - Run whatever it was that you were planning to compress out to your external gear (but keep everything in bypass mode), then back into the DAW on a new channel. Flip the phase on that channel. Now playback your recording of the original track with the newly recorded track with levels matched. Do they cancel each other out? Nope. Close, but no banana.
If you really want to do sample accurate parallel compression:
a. During tracking, create a mult of the desired subgroup (let's say drums), compress/EQ/process and print that along with the individually tracked channels.
b. After tracking, route your desired signal out of the DAW on 2 separate buses. Compress/EQ/process the first bus out and leave the other one unprocessed. Return & print the 2 signals back to your DAW on separate respective channels. No phase issues, no latency, no problem (unless you are using low quality A/D D/A).

If everyone else can - why don't Logic...?
Agreed! The External Instrument plugin in Logic sorts this out to a degree. It allows you to use your hardware instruments as if they were softsynths. The problem is, when you begin to add latency-inducing plugins into your project, things go out of sync. Is it me, or was this not as problematic with older versions of Logic....? I don't remember having the degree of MIDI to Audio sync problems with Logic Platinum 4....
