Yea, I know when I had reflex in front of my hub, it caused issues with midi clock, which in turn caused the small one series pedals to freeze up and crash. With that much going on, I’d say your gonna have issues, I’d try using the analog expression outs only for the hub and then place the reflex after hub, maybe the merge box between hub and reflex so you can at least control reflex from either box. I’m going to try integrating a small secondary midi controller to my board, but I’m keeping it isolated from the soleman as I want to avoid duplicating midi messages to the same pedal. I know when I fed midi clock from two sources to my nemesis (the midi din connector from the soleman and the TRRS from the hub) I got double the time I wanted because of it. Though the controller I’m looking at can disable midi thru, I just don’t need it connected to the hub as it’s really to just control some features more directly and with less programming than the hub/soleman would require to do.
