Hello,
I compose music with Logic and Finale and I really find BIAB great and fantastic for all his possibilities but:
When I listen to latin styles inside, I think they are really great but they are played by jazzmen or if you prefer as american musicians play them. They are not properly played in the original styles.
Have you listened how cuban musicians (who are really great) play their proper styles of music as mambo, chacha, son, bolero and many others?
I ask the same question for brazilian musicians (who are also really great) and typical styles as samba and bossa nova but also chorro, forro, baïon, afoxé and many others.
Just a another remark: the bossa-nova is usually played with a classical guitar by brazilian musicians; I didn't find some in BIAB.
