Muso:

I have been checking the piano roll window after every "Record" (or non-record in this case) session. Nothing.
I took a screen shot of the MIDI/Audio Drivers window.
It's a jpg file.
You may have to open it in (say) MSWord, click and drag a corner to enlarge.
You see that the "MIDI Input Driver" has no driver.
If that is the problem, I don't know how to populate that, nor with what.

Thanks for your help!
