Don't want to sound too critical but I'm sorta' like Fran, I frankly don't see what all the excitement is about (especially at five grand). These are my honest-to-god unbiased observations.

Although the demos sound ok (like something from the bargain bin in the record store), I have yet to hear a end-user presentation that anyone would recognize as coming from the same instrument. In other words, if your stuff didn't sound great on the Tyros, Tyros II, or Tyros III, it ain't gonna sound great on the Tyros IV either. Even on these professional demos, it sounds like absolutely no humans were involved. I know it sounds like I'm trashing Yamaha, and in a way, I guess I am, but this is the most un-organic (non-organic???) music I think I've ever heard. To me, it sounds like music composed by, performed by, and produced (mixed and mastered) by, a computer from a 'B' space movie.

I know there are those that like Yamaha's CD-like, processed sound, and some that hate it. Those that like it should be in sonic heaven, as this sound has now been taken to the ultimate end. Those that hate it may be heading for a Yamaha distribution center in a truck loaded with fertilizer.

Like I said, I'm not biased, but for goodness sake, save yourselves some money; buy a CD player and start heading for that bargain bin (look under 'imports').
