The help file refers to a Pitch Shift function in the
Effects menu but all I can find is a woozly Pitch Bend
which is covered elsewhere in help. Does the function
really exist or am I reading unfulfilled promises?

"Altering Pitch Without Changing the Duration of the Sound

Undo the last operation and return to the Pitch Shift
dialog. In the last two examples, the Preserve duration
check box was left unchecked. When you check this box, a
completely different algorithm is used to change the pitch
of the sound.
Select the Third down preset and check the Preserve
duration check box. Next, you must select a mode. Different
algorithms are included for different kinds of sounds.
These modes are only suggestions, since many will work with
different types of sound. It’s best to just try a few
different ones and choose the one that sounds best to you.
For this saxophone riff, the mode named A13. Solo
instruments 4 does an excellent job.

Now, preview the sound. The sound file will now have a
higher pitch, but it will not sound as if it’s being played
back faster.
