During playback, you can press the Cue Button to return the track to this Cue Point. (If you did not set a Cue Point, then it will return to the beginning of the track.).

STRIP SEARCH: The length of this strip represents the length of the entire track. Place your finger on a point along this sensor to jump to that point in the track (song position). Please note that while a deck is playing “on air” the strip search will not function in order to prevent sudden accidental jumps that may occur if you touch the strip by accident while you operate other controls. If you want to jump on a new position while the track is “on air” please hold down SHIFT button first and then touch the strip to bypass security.

Hold SHIFT and then press this button to cycle through the available pitch range values.

JOGWHEEL: Touch sensitive platter for scratching (vinyl mode), bending (CD Mode) or Grid adjustment. The white leds will rotate according to the software jogwheel position and they will also blink at the last 30 seconds of a track.
PITCH: Controls the track's playback tempo. The Up and Down Arrow LEDs will turn on if the pitch position of the unit and the actual pitch of the software do not match. While one of these leds is turned on, the pitch slider of the DDJ-SX will not control the pitch of the deck until it meets the software value (soft take-over).
AUTOLOOP: Sets an Auto Loop. Hold SHIFT and press the same button to activate a Saved Loop.
HALF/DOUBLE: Halves/Doubles the size of the Loop. Hold SHIFT and press the 1/2X or 2X buttons to move the triggered loop forward or backwards (step is relative to the length of the loop).
IN/OUT: Use these buttons to set a Loop In and a Loop Out point (for manual looping). If a loop is active press the IN button to use the jog in order to fine tune the loop-in point. Press IN again to restore the jog back to its original operation. During the time that the jog can be used to adjust the loop-in point, the corresponding led will blink to notify you of the change. If a loop is active press the OUT button to use the jog in order to fine tune the loop-out point. Press OUT again to restore the jog back to its original operation. During the time that the jog can be used to adjust the loop-out point, the corresponding led will blink to notify you of the change
