I am thoroughly enjoying my 2000, but there is one feature, very different from my PSR540, that I think should be added to the Minus' list.

Yamaha is using LEDs to signal which style pattern is selected and also to signal the status of the 8 registration banks. A RED LED has one meaning, a GREEN LED has another. They also use this RED/GREEN distinction in the LED above the Start/Stop button to indicate the 1st beat of a measure. This interface, fine for most people, is NOT FINE for color-blind people. If I look closely, I can just about distinguish that one of the four style buttons looks different from the others. But there is no way I can figure out which of four flashing beat indicators is different from the others. And there is nothing in the visual panel to indicate the first beat of a measure. In many styles, this doesn't matter since it is obvious where the first beat is. But it isn't always obvious in every style. I do hope Yamaha can correct this problem in the next OS upgrade.
