are you using XVOL or XLEV? XLEV shouldn’t affect cue level, if I’m remembering it correctly. are you in studio mode?

is the fx unit causing latency? delay compensate only makes up for the OT’s processing, would be nice to have more control over that… you can also try using XDIR to fade in the wet signal, if you don’t need to process it further. may help with latency.
