Using midi loopback for routing modulation

Has anyone experimented successfully with using a device like the Quadra Thru or Blokas Midihub to enable modulation of H+ parameters with H+’s own midi output? There is so much midi routing depth that it seems incredibly powerful, but i use H+ midi in and out already for external clocking and triggering external sound sources, so i would need a splitter like the above to be able to do simultaneous loopback and thought i’d see if anyone had done this successfully before buying a news piece of gear.

I was able to make a little loopback thingie for notes, where you can choose via midi CC wich outgoing midi channel from H+ is fed back into a dedicated track on hermod+ (via midihub)
It sure works with note events, and in theory, it should work with CC too… hmmm interesting
