Both look and sound like very good solutions to the issues I'm having.
I have a template in logic pro with all my patch names, etc so I need my setup to revolve around my Mac.
I'm just looking for a bit more of a modern and less bulky solution to what I already have. If I had the ability I'd design something from scratch, but unfortunately, I don't have the skillset to do that.
I know Thorsten and Benoit were looking at an RTP Midi solution and that Thorsten was also looking at redesigning the MBHP_IIC_MIDI module with something like the PIC18F25K22 in order to connect up to 16 midi i/o's to a single IIC port, but I haven't seen much going on on that end.
I've got a while yet. I'm doing a renovation on my place. Literally stripping everything out to the concrete flooring and brick walls and starting again, so I don't anticipate actually re-wiring equipment for a few months at least.
