Actually, I am interested in someone reviewing the acoustic grand piano sound of the Tyros versus any other Yamaha model. I'm beginning to think that the Tyros is all about guitars. I fully understand that the new MegaVoice sounds are all guitars and the Styles have been reworked to include the new guitars and much can be said about the difference a great guitar sound can make not to mention the pyscho-acoustic properties of how a guitar sound is made in the real world.... but the Tyros is still a keyboard and I'd to know about the quality of the sounds that are normally associated with a keyboard. How 'bout that piano: better, the same, not as good?
