<DIV> </DIV>
<DIV><FONT color=#008000>I measure FAC stretch numbers as =
usual and
create the tuning in a memory slot. I tune A4 then move the SAT to =
A6 and
play A4. At A6 the SAT is listening to the fundamental of A6 as =
determined
by the calculated tuning. If playing A4 stops the lights at A6 my =
stretch
for that string is correct. But, the octave temperament octave =
stretch may
not be.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#008000>Then I tune B4 and C5 per the =
calculated
tuning. The FAC tuning changes partials at C5. To be sure the =
octave
stretch is good for this piano I play B4 with the SAT set on F#4 and =
observe how
fast the lights rotate sharp. Then play C5 with the SAT set on G4 =
and
observe the lights again. The speed for both notes should be about =
equal
for a smooth transition across the breaks. If B4 is faster then =
lower your
A4 number and recalculate. And the opposite if it is =
faster.</FONT></DIV>

<DIV><FONT color=#008000 size=3>As usual, the good, well scaled =
pianos don't
need this extra step very often. It's the others that require this =
extra
step.</FONT></DIV>
