Tenor part is double time to all the other parts and won' mute. I've reloaded the xml file, redone it in Sibelius, and it plays great there. But each time I put it in Cantamus, it messes up. I'm using up all my free scores. The first time I did it, it was good, but I couldn't change the tempo. Since then, the tenor part goes double time, or out of time.
