the demo is a limited version and tends to sound very midi. I export the tracks to Cake and mix in cake using what I like from the tracks. check out Sao Paulo Night.most tracks were created in BB, with me on guitar. I have used BB to assist with the last 5 or so songs. Old, New, Pop, dixieland, fast, slow, waltz, and more in the jazz catagory. And JAZZ.there are so many styles here that you can set up all night playing with them and never repeat the same style and just scratch the surface. It's not cheap (depending on the version /level you get, about $400usd) but it has literally hundreds if not thousands of styles and sub styles, and tons of them are bossa, cuban, columbian, raggae, african, and lots of other ethnic styles. IMHO you should look at Band in a Box/real tracks (2009). Well then.why didn't you say so in the first place. Really I'm looking for a (large) set of drum riffs and rhythms (bossa nova, waltz, jazz beats and more complicated stuff) which I can use creatively and for quick construction
