I was going to bring this keyboard to work with me tomorrow. I'm glad I didn't. The keyboard is in self destruct mode. It had buttons going on and off like bonkers. Now I cannot turn on and off Right hand 1 & 2 buttons. What a disaster.

Yamaha had three years to work on this keyboard which pretty much has the same operating system as the PSR3000 with a few changes. I hope this is not indicative of other PSR S900s that they have shipped.
