Press SIZE repeatedly to select the desired loop size.
The selected loop size cannot be seen on your S4; for this, you have to look at the Loop Re-
corder in the TRAKTOR window on your computer screen.
6.6.3 REC Button
The REC button starts/stops recording a loop or additional overdub layers.
If no loop has been recorded yet, pressing the REC button starts recording a loop with a prede-
fined size (previously selected via the SIZE button). The recording always starts on the next
beat. As soon as the loop is recorded, it starts playing (at the level defined by the DRY/WET
knob).
If a loop has already been recorded, pressing the REC button activates/deactivates overdub-
bing. Overdubbing adds incremental layers on top of the recorded loop. Unlike the first record-
ing, overdubbing starts right away instead of waiting for the next beat. Moreover, overdubbing
stays engaged until you explicitly stop it by pressing REC again (possibly going on more than
one loop cycle). This allows you to add as many layers as you want to your original loop by re-
peatedly activating/deactivating overdubbing.
Whatever the number and duration of the overdub layers, the size of the loop itself stays at
the predefined size of the first recording.
6.6.4 UNDO Button
The UNDO button allows you to delete the recorded loop or to undo/redo the last overdub layer:
▪ When the Loop Recorder is stopped, pressing UNDO deletes the recorded loop and all its
overdub layers, if any.
▪ When the Loop Recorder is playing, pressing UNDO undoes the last overdub layer only.
Pressing UNDO again redoes this last layer. This is useful if you don’t like the last layer
that you recorded. It can also be used for “punching” the last layer in and out during your
live performance.
