Lots of great suggestions presented so far. First of all, I think Yamaha beats the completion in the RH voice department particularly with acoustic instruments. I think the main weakness with is within the styles. There needs to be more AUTHENTIC and contemporary Latin styles. By authentic I mean using instrumentation and patterns/phrasing that are true to the style. For example in Norteña music there is no need for castanets and trumpets. On cumbias there should not be a pseudo flamenco acoustic guitar strumming pattern. Salsa needs clear 2-3 and 3-2 clave percussion patterns and bass tumbaos. I could go on and on but in general the Yamaha Latin styles sound too “ball room”. Also there is a need for more contemporary Latin styles such as reggeaton and bachata. Just turn on any contemporary Latin radio station now in the U.S or Latin-American and you’ll hear how popular these styles are. It’s tricky to try to perform these styles on a Yamaha keyboard. I think the problem could be easily resolved if Yamaha hired consultants/programmers that are experts in Latin music.
