I must admit I didn't take into consideration the ChaChaCha Audio style because for some reason (rightly or wrongly) I always felt that Audio styles on a Yamaha have felt experimental rather than serious, not that's a bad thing, although I think I'm right in saying that I don't think those Audio styles are directly being carried over into the SX 900 range for example, or at least any new ones.

To be fair I know there is a old Premium Pack for Latin still available for the Tyros 4 to purchase which I may look into if it isn't too expensive still but having just pre-ordered an SX900 I may just wait anyway and see if they do anything similar for it.

I agree it is certainly down to the player as well.
