Donny,
I agree that navigation on the Yamaha is a piece of cake compared with Ketron and I agree that the 9000s are built (both inside and outside) like "battleships" ("tank" is not enough here...), but I heard you complaining about all those boring 4 bars styles, and -believe me- the Tyros is not such a big improvement! I really was hoping it would! Yes, I too was ready to jump on the Tyros bandwagon, but I couldn't!!!
So: why cannot Yamaha program styles that match their sounds? And why cannot Ketron build their keyboards the way Yamaha does and give itself a decent OS, like Yamaha does?

Terry, my friend, are you monitoring the Tyros Yahoo group? The keyboard is not there yet and someone is complaining already. Perfection does not exist (keyboard manufacturers don't even try to approach it!) and we are all victims of the "programmed obsolescence"!
Aaargh!!!
