if this keeps up I am starting to feel alienated as a American player using Yamaha arrangers vs KORG & Roland in the future. [/quote]

While the ensemble feature seems like a very nice feature which could work very nicely in many types of music, I too feel alienated by the Tyros. I hear no representation of "real" authentic contemporary Latin dance styles. There's some nice Spanish flamenco, ballroom Latin, and bossa nova, but where's the styles that we need in the Americas? The Tyros is very Euro-centric which is forcing me to look else where.
