Anyone who has gotten Chase Bliss pedals (namely the Clean) to work with the Morningstar MC6 Pro, what's your setup/cables?

I've tried using a TRS-TRS cable through the omniport set to different things (ring active, etc), I've tried through the 5-pin port with type B on the other end (which made the Clean's aux light turn green but nothing else happened), I can't get my Clean to respond to anything or even switch channels. What gives? Anyone have any insight before I wing trying to solder a TRS-TS cable?
