There are no good Casio styles programmed for the Brazilian context. Bossa Nova is ok, but Samba and other Brazilian rhythms are poorly programmed in Casio Keyboards until now, including MZ-X . I'm not a fan boy of every keyboard brand, but while in India Casio delivered an amount of free rhythms and tones of good quality, in Brazil only a dozen rhythms of average quality. We don't have good programmers in Brazil Silvano. I already bought some packs and the programming is terrible, with strident sounds, different volumes between them and play like a toy. I also own an SX-600 and would like to be able to transform its styles for the Casio, but I don't have much time for that. Thanks
