Key Concepts
Tempo information: Â Information stored in an audio le that indicates the tempo
at which it was recorded. Apple Loops and les exported from Logic Pro 9 contain
tempo information that the Playback plug-in can use.
Sync: Â Short for synchronize. The Sync parameter lets you control whether an audio le
containing tempo information plays at its recorded tempo or at the current tempo of
the MainStage concert.
Group: Â Each instance of the Playback plug-in can be a member of a group (there
are 26 possible groups, indicated by the letters A to Z). When you start playback of
any member of a group, all members of the group start playing, and all other groups
stop playing. You can stop playback of all members of a group and control other
parameters, including Cycle, Fade Out, Go to Previous Marker, and Go to Next Marker,
for all members of a group.
