Jose, there are some great Latin midi files out there; you have to do some searching. You can take tracks from the song and turn them into tracks for the style you create.

You can also take part of a drum track and copy the claves or congas and create pads. Adding pads to the styles you have can take them up a notch. There are times when I turn the accompaniments off leaving only the bass and the drums and then I add the pads which in many cases gives you a good sounding Latin sounds/rhythm.

Hope this helps, John C.
