I've given up getting the played notes to turn red in the lead sheet view. I just use the notation view. I record the screen with the software Camtasia, which allows me to enter other things under the music staff.

I'm starting to get the hang of it. I've made play-along versions of quite a few songs, and even have 6 subscribers--presumambly people from the chromatic harmonica forum.

Here is my Channel:

I put "Band-in-a-Box" as a key word in all my videos.
