Thanks for the two links where B3 is mentioned. From the tone of MikeK's initial post I assumed Mike knew of a Peter Gannon agreement for more B3 RealTracks so that is what I searched for.

I think contacting Grammy award winning RealTracks keyboard artist Chris Nole and getting him to agree to custom make B3 and other keyboard UserTracks is a bold and great idea. I really hope many Band-in-a-Box users will hire Chris to create custom UserTracks or Artist Performance tracks. I'd love to see a viable third party UserTracks industry develop.
