OT // Trinity Midi Setup w Controller

Using the trinity without a controller is fine. I just tweak the individual machines and away it goes.

The problem is though, I’m about to introduce a controller.

OT: Midi 1-8
MD: Midi 9-12
MnM: Base 13 (but I can only get to 16!)

How can have access to all midi chans, without overlap, using a controller? If I want full control of the MnM I would have to set it 11 but that would conflict with the MD. Or am I missing something with the trinity setup?
