Danny,
Again as usual we agree on what our ears tell us. The Yamaha styles always seem like the same "band" (style writers) have played all the different styles. Even though there are now 4 variations, they don't "move" as much as I would like them to. One of the few complaints I ever hear from X1 users is that the variations move "too" much, and I explain the use of the drum, bass, and chord lock funtions that let the bass line and chord move but keeps the drummer the same and the reaction is "wow, that's killer". In my opinion, you want each style to be the most realistic it can be, which is something Solton has achieved, and where it seems to me Yamaha is still needing to work on. For some, the Yamaha styles are just what the player wants, and for others, they are not exciting enough. This is a beautiful keyboard with many strengths, but the style department is still "Yamaha" and hasn't changed much in all the years they have been providing us with PSR high end keyboards.
