XO Wave: Manage Saved CD Masters

Before actually burning a CD (whether a single copy to listen to or a master), XO Wave "renders" all the audio which will go into the CD (applying effects, pauses, etc.), as well as as the CD metadata. The output goes into a "CDMasters" folder inside the session folder. Once the CD Master has been created, making identical copies is easy. Simply select the master to burn and click the Burn Selected Master button.

On the other hand, CD Masters are not small -- a full-length master is over 600mb -- so if you like one master and no longer wish to keep older or alternate versions, use Delete Selected Masters to clean up old versions.
