Try the reset procedure on page 5 ( last page ) of this pdf document:http://www.dgaudiorepair.com/PDF%20Files/HARD%20RESET%20for%20Current%20KURZWEIL%20.pdf Hope this helps. Note the first procedure says highest white key. I'd do the second procedure.

What has happened is that one signal wire of the matrix that scans the keyboard has opened up. Each key has two contacts. One closes before the other and that is how they measure key velocity to control the loudness for piano sounds for example. When one contact doesn't work, often the sound is set to MAXIMUM key velocity resulting in MAX loudness. The key contacts are scanned digitally in groups of usually 8 or 12 and, for instance, every C key has a single line attached and then every group of 8 or 12 has a second line and then there are two complete sets of these to implement the velocity sensing. Your unit probably has either a break in a cable or possibly a cable connector that has failed or not seated OR worst case, the circuit board under the keys has a crack breaking one wire or circuit trace going to that section of the keys. The problem will require opening the keyboard to repair. If you are not electronically adept, besst to take this to a repair shop.
