[CAUT] IPod and Tune lab

[Keith Roberts]

Usually I use either the 4-2 singleoctave or the 2-1 singleoctave. You have
to hit the auto button to adjust the upper curve to the new selected partial
scheme. Notice the increase in the center spread on the lower graph and the
sharper treble on graph 2, 2-1 octaves. Narrow gap in the bottom graph is
desireable
You can now use the manual adjust to vary the upper graph. I use the 8
button adjuster. Usually I don't need to adjust much.

The upper graph is the curve the program sets the piano to when you hit the
exit button. Nothing else changes the curve except going back to the graphs
and changing things there. Play with it. There is more of a learning curve
with tune lab but you can do stuff like perfect 12th tunings etc.

If I don't get a graph that looks like these, I retake the readings.
Sometimes the split scale method has to be used
