Two computers at once. MIDI Connections: MRCC, SSP, & Ableton. USB how to do so?

Without adding every little device, I've sketched up the above.

It sounds like you already have one MRCC.  If so, test whether your SSP can handle the 12 virtual ports coming from the MRCC's device port, or at least work adequately for your needs before getting a second one.  Disclaimer: I had never heard of the SSP before, and only half understand your objectives, so this is just a thought.  I do have 2 MRCCs, though, and they integrate nicely together.

Yes, I tested the SSP with the device port on the MRCC. It works great.

I went about ordering a 2nd MRCC from Thomann as they are finally on stock. I'll report back when I get everything set up. Although more expensive than I'd wanted, it will hopefully make for less hassle with all of cabling when taking the core pieces out for live gigs. 

Thanks for the feedback and information.
