However, I've been banging for a good 30 minutes now to no avail. It's easy to do. Diana's dream worked for me as well. Tried Diane's tip as well, as the fellow I just sold my keyboard to rang to say two keys all the way down the keyboard weren't working. Woot. This is happening with greater frequency in the past few weeks. Fixed. Had all my "C" keys not functioning in my Electone F-15. REMARKABLE!!! tried Diana's trick, great for at least 1 day, so far!

Tipping the keyboard onto its side did the trick when some keys aren't working. *Deep sigh* I wish there was some way we could collectively file a grievance to be made whole with our investments in Yamaha products. Introducing a new standard for keyboardists: the YC stage keyboard and CP stage piano. All but one works perfectly. I found a solution on another webpage. No thanks to Yamaha.
