Hi Dragonsting,
The Preserve Pitch button allows the user to change the tempo of a song without changing the pitch of the song. If you take the Preserve Pitch off and change the tempo, the Pitch will also change.
However, you can also change the pitch of your song in the Mixing palette. If you drag and drop your track into the palette, right click on the track and select “Insert” > “Pitch Envelope”, you will be able to change the level of pitch up and down.
To learn more about changing pitch, please view “Cut + Paste Samples/Add Effects” video at:

The information about Pitch begins at 6.02 minutes in this video.
If you anymore queries, please do not hesitate in contacting us,
All the best,
Colm
