I am looking for Latin dance Styles for Roland E96. Merengue, Salsa, afrocuban, Cumbia, Vallenato, porro, Chacha, mambo, rumba, danzon and Brazilian.

Hi timbales9,
try the following links: http://www.roland.it
(you then select the download section and the arranger keyboard section);
another good site for latin styles is the site of Roland Brazil: http://www.roland.br
Finally, you can try the Roland Arranger Group: http://www.daytona.com/rag
Good luck,
Andrea
