There has been a lot of discussion the past few days regarding "mega", "Natural", and other voices that will be in the TYROS keyboard.
I spoke today with Mr. Mark Anderson, product manager for Yamaha and got some additonal information that should help.
Mark informed me that very shortly more info will be made available by him on the Yamaha website explaining more in detail about TYROS. He stated that in the first sentence, it will say that TYROS is a product developed to be as easy to use and navigate as a Clavinova and as powerful to program as a Motif. In other words, this is a new keyboard and shouldn't be mistaken for a Clavinova or a Motif. There is not the same features as either a typical Clavinova or a Motif, but rather a newly developed product.
Natural voices are not used in TYROS, and again, even though a sound is called "harmonica", the "harmonica" in TYROS can be completely different than the "harmonica" in a PSR2000 although they both have the same name.
I also got information about hard drives for the TYROS today. In the PSR9000 and 9000PRO, only certain hard drives would work and only a maximum of 8GB could be recognized. Yamaha sells a hard drive in the $400.00 price range. For TYROS, Yamaha has tested many different manufactures lap top hard drives and all they've tested work fine. There is also no limitation to the size that the keyboard will read. However, with no sampling option, you won't need to buy really large ones. Now, low cost drives may be used.
