pitch raise question

[Cy Shuster]

Look again at the overpull options.  If you haven't selected "Measure every 
note", you're missing one of TL's best features: its automatic calculation 
of the correct overpull percent for every string.  The percents you list are 
the maximums that it will use, in this case.

Here's how I use the overpull auto-measure:

1.  In the overpull options, tell TL the highest wound string (to avoid 
breakage), and clear the history list.
2.  Set note-switching to "Manual only", and set TL to D#1.  Play the note, 
and watch the upper-right-hand corner to see the overpull (or underpull) 
that it calculates.  It does a very fast pitch measurement.
3.  Don't tune the note; go down to D1 and play it.  Repeat down to A0. 
This step loads the history, so Robert can calculate a moving average (see 
the lower left).
4.  Set note-switching to "Auto up".  Tune A0.
5.  Play A#0.  TL auto-switches to it, measures pitch, and calculates 
overpull.  Tune and go up.  Notice after the monochords end, you need no 
mutes, since you see all the strings in the spectrum display.

If the pitch measurement isn't right because of problems note-switching, 
just click on "M".  In overpull mode, this activates the quick pitch 
measurement.

After C8, go to the overpull dialog to turn it off.  The average overpull 
appears near the "Clear history" button.  I find it useful to let the 
customer know what this is.
