James,
I just listened to the full vesion...WOW!....are all the sounds from factory M3 or are the voices from your own custom ones?

Also, Sibelius has a light version for around $99 and I am thinking of getting it. If I do, I'll let you know how well it works. You can upgrade to the full pkg later if you want.

You could play and Sibelius would create the score and you can print it out.
