How to change and save the key of a karaoke song?

To change the pitch of your karaoke songs, follow these steps:

• Open the song you want to tweak
• Press the Up or Down arrow next to the "Key" control in the upper right hand corner to get a higher or lower pitch

What if I want to save the pitch for next time ?
It's fairly simple. Just add the karaoke song to any playlist. In this playlist, click on the karaoke song, and a control bar should be displayed at the bottom. That's where you can setup your permanent settings.
