Hi Kabinopus, I was interested to see your comment, because I have completely the other perspective. It always frustrated me that Yamaha strings would not hold the sustain if the pedal was pushed. In a real musical situation, the strings may continue even when the piano is silent, at least Korg gives that option while your hands are doing something else: changing variation, adding or taking away voices, fills...

So, Tony's Ricki Nelson quote is very appropriate!
