Why I don't know. I always assumed it was a poorly designed key frame. But perhaps it is made that way on purpose. When leveling keys, don't we want a 1/16" crown in the middle? Perhaps what K&B did was put that crown in the keybed, and made the frame flexible to allow it to conform to the bed, without putting tension on the frame. Willem </HTML>
