<DIV>Are you using a SAT or other ETD? If so, why not just use the pitch =
raising
feature on the machine. They all work quite well. If you are doing a =
large pitch
raise, don't use the pitch raising feature on the machine on the =
first
pitch raising pass, just target pitch. Obviously, use anything you find =
easy and
that performs well. But otherwise, the pitch raising feature on the SAT =
or
whatever device works great.</DIV>

<DIV>I know I did not answer your question directly, but that's my
thought! :-)</DIV>

<DIV><FONT face=Arial size=2>(Dear list, </FONT><FONT face=Arial =
size=2>I'm posting this again, hoping for a =
response.)</FONT><FONT
face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2> I've been =
experimenting with
an old pitch raising technique for instruments which are more
than 30¢ flat that works for me, but want to improve it and =
would like
some feedback.</FONT></DIV>
<DIV><FONT face=Arial size=2> I strip-mute the =
whole
piano, over-pull the wound strings (3.5¢ max.), then taper the =
over-pull
from +5.5¢ in the tenor to as much as +10¢ at C6and up. When I =
encounter an
area of the piano that is more than 30 cents flat (that is, where =
I would
be over-pulling by 10 cents), I change over from tuning unisons to =
quickly and
<EM>quietly </EM>tuning only the center string (+10¢ max) =
without
pulling the mute. Then go back to the unisons and continue =
with the pitch
raise and the tapered over-pull.</FONT></DIV>
<DIV><FONT face=Arial size=2> This quick =
pre-loading of the
board before the actual "pitch raise" seems to get me to pitch faster =
(2 pitch
raises max), <STRONG>and</STRONG> being one who has broken a plate in =
a
client's piano by overstressing <EM>one</EM> area of the
plate, it gives me a little more comfort when I'm doing a 100¢ =
p.r. to
have 1/3rd of the scale at pitch before pulling up the rest. =
</FONT></DIV>
<DIV><FONT face=Arial size=2> I have also
(unsuccessfully) experimented with this technique where the piano =
needed only
a small p.r. (say, under 10¢) and time was short. I don't know if =
this is just
a bad idea, or if I'm not calculating the over-pull properly, but I'm =
far from
the mark. </FONT></DIV>
<DIV><FONT face=Arial size=2> How do I calculate =
the
amount</FONT><FONT face=Arial size=2> to over-pull that =
center string in
the above scenarios, and what are the opinions of the second scenario? =
