Hello all. I just got a Morningstar MC6 Pro MIDI controller. The problem is that I can’t select it inside the plugin. It is showing, but it is greyed-out and I can’t check that box. I CAN check the box when my IK Multimedia AXE IO (with MIDI) is connected also.
Is the MC6 not compatible with the Neural plugins? I am trying to use the stand-alone version of the plugins.
Any help would be greatly appreciated. 
Your Morningstar controller should show as at least 4 different ports to choose from in your NDSP plugin → MIDI Input Devices.
If it doesn’t, you have either faulty cable, USB port or controller.
My guess is that you have figured it out by now, but forgot to come back here, and share what was the issue.
Anyways, I’m posting this reply for others who may encounter a similar issue.
