I'm trying to record MIDI input, not audio.

"What selections do you see in the MIDI INput window of BIAB" - I only have two options listed in the LH MIDI Input Driver window:

<No MIDI/sound input>
Roland XV-2020

The latter is selected/highlighted blue, and appears in the top single line window. Whenever I have the MIDIMAN MIDISPORT 2x2 connected, I see that one too. BUT, it's not connected and I'm not using it now - so it's not in the list.

I'd include a screenshot if there was a way to do it.
