Hi Joe: You make an excellent point. My Technics keyboard uses a 4 LED system to keep track of beat/time. The first LED flashes RED for beat 1, the second LED flashes green for beat 2, third LED green for beat 3, and fourth LED green for beat 4. This way, even if you are color blind, you will at least see the lights flashing from left to right. When I first got the PSR2000 (though I'm not color blind), it took a little while to adjust to ONE flashing LED light changing to red on beat one. I've adjusted to this now, but I definitely would have prefered the 4 LED indicator approach, because that way you always know exactly WHICH beat in the measure you are at.
