<DIV><FONT size=2>As a general rule I am finding that small pianos =
require an
entry of -.5 on the DOB and as the pianos get bigger that number
decreases. But you can measure the stretch before you =
start by tuning
a double octave (after entering the FAC numbers and saving), and testing =
aurally
to see if it is where you want it. The SAT uses A4 as the fixed =
point so
keep that in mind when you choose your test double octave. I =
usually try
and test the double octave to not include any wound strings. If =
the double
octave is too wide, input a negative number on the DOB and change notes =
(step
up, step down) to implement the change. Test again. When you =
get it
where you want it go ahead and start tuning. When tuning with the =
SAT I
start in the tenor and go up (when tuning aurally, I start from the =
temperament
and go down). When I am done with the treble I usually direct tune =
the
bass as the machine sometimes has problems across the break and I don't =
always
agree with its choices for stretch in the bass. Jim Coleman has =
made
several contributions to the list regarding use of the DOB. I =
recommend
you search the archives and check them out. </FONT></DIV>

<DIV>I would sure like to hear more on this topic. As a tuner still on =
a steep
learning curve, I wonder just what I should be doing with my octaves,
but I find that the SAT III is either right where I wish it to =
be, or
sometimes I do find that it seems to have calculated a tuning with too =
much
stretch, and I have to enter negative numbers in the DOB to slow the =
beating
down - occasionally quite a bit.</DIV>

<DIV><FONT size=2>My experience suggests that C8 at 43+ is not a

usually
reduce the stretch (on the SATIII via the DOB). =
On concert

smaller

<DIV>You've talked quite a bit of your "tempered octaves" but as =
one who
has seen everything from 2:1 octaves to outrageously stretched =
octaves I
don't know what kind of stretch you're talking about. Could =
you give
us some numbers so we can know what you mean by tempered =
octaves?
</DIV>
<DIV> </DIV>
<DIV>For example, when I tune a Steinway D my C6 is stretched to =
5.06, C7
is 16.11, and C8 is 43.84. This is what I consider a =
conservative
tuning. What kind of numbers do you get? On any piano, =
just
measure your C6, 7, & 8 and tell us what model piano it is, =
and how it
stretches with your tempered octaves. That would be very
informative.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
