Ever wanted to do a cover of a brazillian song? What about a little touch of the Bossa Nova laid-back cool on your material? Check Beatriz Kauffmann's massive midi archive. And you know what? It's all free!
The site is in portuguese, so for all you non-portuguese speakers, too bad! Just kidding: scroll down and you'll find an alphabetical index to take you pretty much wherever you want to go.
