Leezone,

I am sure you are aware of this site, but since you are such a fan of Brazilian and Portuguese music, I would suggest obtaining the styles specific tailored for those music types, right here:
http://www.fcmusica.com/shop/?en_ritmos-para-ketron-audya,171

As you also speak Portuguese, another site full of good Portuguese/Brazilian/African styles (I bought some for me and I can confirm they are very good) is:
http://www.midiarte.pt/loja4/index.html?lmd=39632.655370


Cheers,

Carlos Silva
