Studiologic Numa Compact X2

Hi,

I've recently installed Mainstage and I'm trying to set it up with my new Studiologic Numa Compact X2. The problem I'm having is that the NC2X has 2 midi ports - Keyboard & Controller. Keyboard out is dedicated and fixed to send out on MIDI CH 1 & 2, and Controller can be setup to send on MIDI CH 1-16. The problem is in Mainstage it sees both inputs but they are greyed out so I can't select one or the other. Which means all my notes are double triggered and out of phase. Anyone have any ideas? The controller shows up in Logic, Digital Performer, and Kontakt standalone just fine - with select able midi inputs...but not in Mainstage. Thanks for you help!
