Using the Sync Parameter
The Playback plug-in also includes a Sync parameter. For audio les containing tempo
information, you can use the Sync parameter to control whether the audio le plays at
its recorded tempo or at the current tempo of the concert. If you choose O from the
Sync pop-up menu, the audio le plays at its original tempo. If you choose On from the
Sync pop-up menu, the audio le plays at the current tempo of the concert.
