Appendix A The Playback plug-in 131
Playback information display
The information display shows information about several key aspects of your audio material and
lets you edit some of the displayed values.
Information Display parameters
Position eld: Shows the current position in hours, minutes, and seconds (when Sync is o), or
in bars and beats (when Sync is on).
Length eld: Displays the overall length of the loaded audio le in hours, minutes, and seconds
(when Sync is o), or in bars and beats (when Sync is on).
Meter eld: When Sync is on, lets you dene the meter (time signature) of the audio le. The
bar and beat values can be altered independently. Editing the Meter eld changes the ruler
display, and may alter the Length eld display, but has no impact on audio playback.
Tempo eld: Displays the MainStage concert tempo in beats per minute when Sync is on.
Playback follows only a single, constant tempo. The Tempo eld is disabled when Sync is o.
Note: Because Playback instances use the concert tempo when Sync is on, you can use audio
les recorded at dierent tempos, and have them all play back at the same tempo (the concert
tempo).
Fade Time eld: Sets the fade-out time in seconds. Drag vertically to adjust this value. Click the
Fade button to start or stop a fade-out.
Pitch elds: Transpose audio playback when Sync is on. Drag vertically in either the semi or
cent eld to transpose the audio le in semitones or cents (1/100 of a semitone). The Pitch
elds are disabled when Sync is o.
