Thanks for this – using the wet/dry mix on the Heat would be OK, and I actually have a few of those Hosa cables. I think it finally dawned on me how the inserts work! In my particular set up, though, this will mean taking the Heat out of my patchbay — that’s fine and it’s not that big of a deal to just re arrange the cables if I ever want to use the Heat for processing things separately. It would be great if the AUX 3 & 4 on the ZED weren’t hard wired to be summed to mono — I’m sure there are technical reasons for that, but as a feature request having the option of using them for a stereo post-fader AUX to external effects would be great.
I’ll give the inserts a try, and thanks again!
