I said = it was the flex of the key, which in my inexperienced mind means larger grands are = more prone to have flexible keys. Small grands are made cheaper and may have = as much flex or more. I don't know. My postulate was that we have to take into = account flex and delay in order to affect release velocity with the punching = change. David detected no change in sound in his test. His test was only the = difference between a hard punching and a soft one. The two extremes. So if on a = soft blow where there would be little flex, there is also an "improvement" of = tone, I would have to agree with Stephane and attribute part or all of = the change in sound to the removal of a "garbage" noise. I believe Andre keeps = saying the sound is clearer, not necessarily louder. ?</FONT></DIV> <DIV><FONT face=Georgia size=2></FONT> </DIV> <DIV><FONT face=Georgia size=2>kpiano</FONT></DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>----- Original Message ----- </DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=quentin.codevelle@tiscali.fr href="mailto:quentin.codevelle@tiscali.fr">Quentin Codevelle</A> = </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Saturday, January 29, = 2005 8:18 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> ***RE: your punching comments</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial size=2>Yes Keith,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>But the difference can also be = noticed on smaller grands.</FONT></DIV> <DIV><FONT face=Arial size=2>So the size of the keys can't be the = only solution to explain the increase in tone.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial = size=2>Quentin</FONT></DIV></BLOCKQUOTE></BODY></HTML>
