Looking at the pitch control, you'll see a Pitch Select function at the top, allowing you to switch between an 8 percent and a 12 percent pitch range. In the middle you'll find a Pitch Lock button, which quickly locks the speed to an unaltered original setting. At the bottom you'll find the Key Lock button, which serves the unique function of maintaining the original, unaltered pitch of the recording, yet allows you to slow down or speed up the song's tempo.
