<html> <body> Hi RicB, Kawai showed this at the Dallas PTG exhibit, and we had two models at NAMM (VT-132 and VT-118).  The system works with weighted levers mounted to a moveable rail.  The levers rest on a secondary capstan on the keys, located in between the balance rail and the regular capstan.  By moving the rail in and out, you move the levers on top of this secondary capstan, and thereby change the capstan's contact point on the levers. It's really very simple, and easy to service.  The whole rail can be removed and replaced when servicing the keyboard without changing the regulation of the levers and their upstop rail. I can supply a PDF service manual to anyone who wants one and has a good internet connection speed.  If you want it, write to me at the office at dmannino@kawaius.com.  I cannot send it from home, so please do not reply to me at the address in this message.
