If the tape loop length has been set, pressing the Fade Out button (or activating a
screen control mapped to it) while Loopback is playing clears the buffer, but does not
reset the loop length. Pressing the Fade Out button while Loopback is stopped clears
the buffer. If the loop length was undefined when Loopback started playing, it also
resets the loop length.
• Count-in button:Enables a one-bar count-in, using the concert time signature.
• Metronome button:Turns the MainStage metronome on or off.
• Undo button:When pressed during playback or when stopped, removes the most
recently recorded take from the tape loop. Pressing Undo during the first beat of a new
take removes the previously recorded take.
MainStage Loopback information display
The information display shows information about several key aspects of the audio material
in the tape loop and lets you edit some of the displayed values.
Information Display parameters
• Position field:Indicates the current playhead position.
• Length field:Displays the length of the loop.
If Sync is set to Off, Loopback analyzes the first take and determines the tempo and
length, using the concert tempo as a starting point. After the length is set, it cannot be
changed (until you clear the tape loop).
If Sync is set to On, you can set the length (in the information display, or using a screen
control) before you record the first take. If you do not set the length, Loopback analyzes
the first take and sets the length using the concert tempo, rounding up to the next
whole bar.
• Position dial:Displays the current playback position in the context of the overall loop
length.
• Meter field:Displays the meter (time signature) of the audio material. The bar and beat
values can be altered independently, which changes the ruler display and may alter the
Length field display, but does not affect audio playback. It cannot be changed once the
length is set without first clearing the tape loop.
• Tempo field:Displays the tempo in beats per minute. The tempo is “locked” after the
first recording and cannot be changed.
• Fade Time field:Indicates the fade-out time in seconds. Drag vertically to adjust this
value. See MainStage Loopback transport and function controls.
