Topic: Patching an external effects pedal into total UCX

Hello I have posed this question before but still haven't been able to find a solution.
I have 2 mics on an acoustic  guitar going into RME fire face UCX inputs 1&2.
I have a reverb pedal which is the meris mercury7 which I want to patch into the UCX.
After I have recorded my dry guitar signal,
I want to tweak in real time on another track, the mercury7 effects over the dry track. Is this called re-amping? (but without the amp?)
How can I route this in total mix fx and in Cubase or logic pro x?
Any help would relieve a long standing and confusing problem and I would be most appreciative!
