Hi, Sure this kind of thing has been asked over and over, but I was wondering how hard it is to replace a broken key on a Roland keyboard. I have a KR-570 Digital Piano and an upper register Bb has lost it's bounce... It still makes sound, and is not stuck really (you can pull it up quite easily), but just sits as if the key was being pressed. I assume the key itself is broken, or else some related spring mechanism that gives it the 'piano feel'. Any ideas where I could find how to fix this would be appreciated... - Jason
