Thanks Noel! It is only a MIDI track I am interested in and not an RT.

I already tried video capturing the screen and reintegrating it with audio in a video editor. The problem is it is really difficult to exactly line up the video and audio. I tried several times and it always seemed to drift out of synch over the 5 minute duration of the song. And the moment the highlighted piano keys don't match the audio it becomes useless as a teaching tool.

I was hoping this could be output to video with the Big Piano window intact for a perfectly synced video.
