yes, I played with 3 programs a while ago. Unfortunatly I cant remember any of their names at the moment, but one was very good. I made a few scores up for my trumpet, it was too hard to play holding the big music book. Just look around, you will find them. They are out there though.
This was the one I liked, but I think there was something funky like you have to find a GUI front end or something? Anyway, once you figure this out it works great.
