I've been gigging with my Tyros for OVER 2 years now w/o a single problem with case durability. I for one appreciate its portable 27 lb convenience vs lugging those 40+ lb kb monsters of yesteryear.

As far as styles go, I find the Tyros internal styles themselves EXCELLENT, and with the exception of muting the internal style's auto accomp 'keyboard comping' parts, and playing them in live instead, for most all my performance requirements, the PRESET styles cover most all the bases. I feel that the only commercial styles that approach the quality of the Tyros internal styles are from: MidiSpot or Yamaha. I've long ago stopped wasting my time spending hours attempting to convert styles from other manufacterers as most of these styles are already INCLUDED by Yamaha. Better to spend time actually PLAYING the keyboard rather than tweaking I say. My 2 year love affair with Tyros continues. - Scott
