Using the Loopback Waveform Display
The waveform display shows the waveform of the recorded audio material. The waveform
display updates in real time as you record new material. The vertical line in the center of
the display is the playhead, which shows the current playback or recording position as
the waveform scrolls from right to left. The ruler appears above the waveform, showing
bars and beats (musical time).

• Record button: Starts or stops recording. Click the Record button once to start recording
to the tape loop—a virtual tape loop, not an actual one. Click a second time to set the
length and start overdubbing. During overdubbing, the first recorded take plays back
while you record subsequent takes. Subsequent clicks toggle recording off or on, while
the tape loop keeps playing.
• Play/Stop button: Starts playback at the position set by the Play From and Snap To
parameters. If Loopback is playing or recording, stops immediately (without waiting
to reach the Snap To value). If loopback is recording and has not established length it
sets the length and just continues to play back with no overdubbing. See

Loopback Sync, Snap To, and Play From Parameters .
