Hi, Alec. The PSR 6300 is not the only instrument that Yamaha did that on their demo's. I had a small organ that was the same way. Impossible to duplicate what their demo could do. Nice to get your second card 'free' but a lot of trouble having to replace your keyboard to do it!
Interesting to read so many of us had the 6300, it was my first keyboard, I had been playing organ before that, and decided to add a keyboard since they seemed more fun. Now I strictly play keyboard.
This topic started out about the "looks" of the KN7000, I kinda like it. Maybe it's the nostalgia of the flip top.
