Hi Walt,
BIAB is an interesting program, but I don't really use it much either, except for fiddling round with style creation for the kn7. I really don't have the spare time either to check BIAB thoroughly.

As for the waltz, it's only a really simple one. ( I was mainly trying to give you ideas to try)
The waltz only consists of bass, piano arpeggio, strings & french horns ( no drums) so probably not terribly exciting to most.
I decided to try & create it for the song "Always" (Irving Berlin).

I'm a Richard Clayderman fan ( nutter in fact , I've got most of his albums
( dozens) , much to hubby's dismay)
Anyway, I'm really fond of piano arpeggio's. I wasn't too good at playing left hand arpeggio's on my piano, so now I cheat and create the odd arpeggio style. Gives me a false sense of actually being able to play
( haahaa).

If you'd still like a copy when I finish, let me know. I personally like simple styles, but bear in mind, there's probably a lot more that could be done with it by incorporating phrases ( like drums) or substituting strings from the kn7.

best wishes
Rikki
