OK, the problem was in my Midi Port Setup in the Device Setup. I did not have the check boxes checked for “In All Midi” for the 3 Ins so they were “inactive”. Once I checked those boxes they became “active” and I could then set the Midi in and out channels in the Remote Devices window.
I ended up setting Midi Input to CMC-PD-2 and Midi Output to CMC-PD-1.
I hope that helps someone who has the same issue as me.
Now go create some music!
