Just remembered something else... I'm sure everyone remembers when the PSR-9000 was first released, and all the horror stories with the operating system in the machine.. There were MANY complaints of the aftertouch not working properly, hung notes, notes suddenly going out of tune, and much more.... Yamaha released this keyboard knowing it had all those bugs, but already knowing this they had the techs working on the OS upgrades before it even hit the market....
