I would be happy to try and fulfill your request if I could get the music without the vocal track. I am curious, though... if you are doing a cantata, then why do you need the music at all? Just use your musicians and practice getting the tempo right and do it all live with no sound from the video whatsoever. @Ellen:

Our church is incorporating "Breath of Heaven" into a cantata and after seeing your movie clip, I won't be satisfied until we can show it with the solo. Were you able to come up with a version minus Amy Grant's voice? Or if I could provide the background music, would you still be able to combine that with the movie? What would you charge to do that? Thanks so much. I have the same question as Traci.

It's streaming live, so you certainly can't stop that part, but it may be possible to divert the stream through the fifos to <code>/dev/null</code> when a button is pressed and go back again afterward. I honestly don't have the "code fu" to do anything like that or to answer your question without a lot of fiddling and researching. I'm glad that you find the code useful, and I do appreciate your posting here with updates when you make interesting modifications.
