The customer = was complaining that several notes in the low tenor area were not = sustaining. When I got there I found that these few notes were double striking = and sounding like they were blocking when played lightly. Actually = anything up to a light/moderate keystroke.</DIV> <DIV> </DIV> <DIV>I checked the position of the let off rail and regulation in = general. So far things looked fine. Moving the key down slowly produced let = off at about 1/8" and there was sufficient key dip for plenty of after = touch. Back checking was fine. I went to the worst one and to satisfy my = curiosity, cranked the button down to where let off was about 1/2". This = changed nothing. The hammer was still bouncing off the top of the jack. Only = on a very firm stroke would everything cycle through as it should. Most = of the piano was just fine. It was these few notes.</DIV> <DIV> </DIV> <DIV>Well, it only took about five minutes to figure it out, but it = was a long five minutes with the customer watching. Anyone want to guess = on this one?</DIV> <DIV> </DIV> <DIV>Dave Bunch</DIV></BLOCKQUOTE> <P> <HR> <P></P>No virus found in this incoming message.<BR>Checked by AVG Free = Edition.<BR>Version: 7.1.362 / Virus Database: 267.12.7/160 - Release = Date: 11/3/2005<BR></BLOCKQUOTE></BODY></HTML>
