Got my Yamaha bubble buste in the last few weeks. A few months a go i reported that my PSR 2000 went south. The D&E buttons along with ending, break, fade in & out plus Jazz and swing and a few other problems arose. That keyboard is currently at the GC for repair. Yesterday after doing a nursing home gig, i stopped by Dano's City and tried out my Yamaha YSTMS50 speakers and lo and behold my Tyros acted up also. The basic same thing happened to it. The D&E buttons on the screen will not work. Anothe Yamaha keyboard in the shop. I'm leaning towards never buying anothe Yamaha product for the rest of my life. It's either shabby workmanship or Yamaha parts are not going to last very long. My keyboard( Tyros) is only about three to four months old, so it is still in warrenty, but if it is not going to be reliable, then what good is it?. When it works it is a great keyboard, but the question becomes" How long will it be reliable" . Really ticked, Bob
