I´m from Brasil and at first I was very well impressed about BIAB possibilities. After some time as a user I finally quit using BIAB due to its 2/4 incompability. Playing bossa nova nylon guitars in 2/4 time melodies sounds like... bossa nova. To me its very weird the lack of efforts in developing samba RT. I came back to this forum after three or four years hoping to see some good news...it´s a pity.
