While I do not use my MIDI controller as a control surface, I have seen other posts that seem to indicate that any MIDI port that is use for your control surface should not be used as a MIDI track’s input MIDI port.  Some MIDI controllers even have two MIDI ports - one that can be used for a control surface and the other as a MIDI track’s input MIDI port.  I know my PCR-800 does.   You might want to go a head and post this question as a separate post.
