@bassbene Thanks for the advice. I followed your lead and played with different block options under the FX loop header, of which, Return R happen to work without plugging in an additional patch cable. Definitely a bummer to have to use up a block for this but glad to have a solid workaround.
I also found that the system worked nicer when I mixed the wet signal back in prior to the rest of my modulation effects. I don't mind if my trails have chorus on them, etc... more the drives that can muddy up the mix real quick.
Thank you!
