Hi UD & Don:
Mike's Tyros would not hold settings or even respond to a "system reset." I suspect it has something to do with the hard drive (20 gigs)installed a day or two after he received the Tyros. The installation was a snap and the Yamaha instructions were painless. Being an old DOS person, I could not believe the format happened so quickly. Makes me wonder if Yamaha and Windows XP are shaking hands properly? Don, you are correct in assuming Mike took it to the place you described in Shreveport.
