- NEEDLE SEARCH STRIP. 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). While your finger touches the strip, the track will start a temporary playback (if it was not playing before) in order to preview that area of the track. Lift your finger from the strip to stop playback.
Important notice: In order to avoid accidental track jumps when you manipulate FX, the needle search does not operate when the deck is on air. If you want to use the strip while a deck is on air please hold down SHIFT first, and then touch the strip. You can change this behavior by changing the Needle Search Security setting. (See Special Settings)

The outer white/blue leds will start blinking if the track reaches 30 seconds before the end.
The inner white leds will rotate according to the software jogwheel position.
The inner red ring indicates the loop's progress bar if a loop is active, or current hotcue's position on the jogwheel rotation. If Slip Mode is active, among with the current hotcue's position, the red leds will also show you the slipping rotation of the jog.

- TEMPO. Controls the track's playback tempo. The Up and Down arrow LEDs will turn on if the tempo position of the unit and the actual tempo of the software do not match. While one of these LEDs is on, the tempo slider of the DDJ-RZ will not control the tempo of the deck until it meets the software value (soft take-over). Move the unit's tempo slider towards the direction of the LED that's turned on until it turns off. Now you can use the unit's tempo slider to adjust the tempo of the software.
