Lightening touch by changing damper timing redux

Having the dampers lift at let-off would definitely be too  late.  What=20
happens is when you change to lifting the damper when the  hammer is, say, 2=
/3 of=20
the way to the string is that it is closer to let  off and feels more like a=
=20
longer, contiguous bump, rather than two separate  ones.  And as Dean noted,=
 the=20
fingers have more speed at the  point where the key contacts the underlever.=
 =20
Makes a big difference.

You can always try it on your action model...

I'll be doing the warranty tuning on the 1st piano I did this on--some  6=20
months ago-- next week.  I'll give a report, and am fully prepared to go  be=

  Please hear me & with all due  respect.  I can feel that .
   Actually, IMHO,  an 1/8 th inch in  damper lift timing can make a HUGE =20
difference  in action feel especially with high ratio actions.  Frankly it=20
doesnt'  concern me what Seiler might think but rather my  clients.
   There is a sweet spot for ,most pianos,  & when setting this up  I find i=
t=20
most often that spot to be at  half travel when the key aciton cycle is at=20
it's most efficient & friction  free spot in  movement  Picking up the dampe=

prematurely can  increase the feel of touch weight or heavy touch syndrome=20
dramatically on some  actions.   I'm always looking for the optimum sweet sp=

The damper timing I thought was  determined by the manufacturer.  When the=20
key goes down it meets a  couple of resistance points.  One, the end of the=20=
key =20
contacting the damper lift lever (but who can feel that?) , and  two, the=20
jack contacting the let off button. (which everybody can feel)  Since the co=
ntact=20
between the key and damper lift lever is  what,  1/8 inch leeway what=20
difference does it really make?  The most  important consideration is that d=
ampers=20
lift as a unit as the damper pedal  is depressed so that =E2=80=9Chalf dampe=
ning=E2=80=9D can=20
be utilized. =20
I can imagine asking any of the  piano makers including Seiler who show up=20
for the National Convention where  they prefer the key to hit the damper lev=
er=20
and why.   ---ric   _www.pnotec.com_ (http://www.pnotec.com/)  =20
