Hold SHIFT down and then press this button to set this deck as Master Deck. While SHIFT is held down, the Master Deck's SYNC button will be lit.
When the LED blinks, it means that the manual Master Deck selection mode is active (i.e. you had manually selected the Master Deck). Press the flashing button to revert back to the Auto-selection Master Deck mode and let VirtualDJ to decide which Deck is Master mostly based on the deck that is playing out live.

- LOOP IN. Press this button to set current position as the Start point (Loop In) of a manual loop. When a Loop is enabled, press this button to set Jogwheel to Loop In Adjust mode and use the Jogwheel to fine adjust the position of the Loop In point in time.
- LOOP OUT. Press this button to set current position as the End point (Loop Out) of a manual loop. When a Loop is enabled, press this button to set Jogwheel to Loop Out Adjust mode and use the Jogwheel to fine adjust the position of the Loop Out point in time.

When Track is in Loop, hold SHIFT and then turn the encoder to move the loop backwards/forward by 1 beat
- SLIP. Press this button to enable/disable Slip mode. When enabled, several actions like scratching, Hotcues, Loops etc will act temporary, and the track will resume playing from the position it would have been if the action was never triggered.
- VINYL. Press this button to set the Jogwheel to Vinyl (Scratch) or CD (Bend) mode. In Vinyl mode, use the outer part of the Jogwheel to bend (temporary speed up – slow down the tempo of the track).
- JOG. Touch sensitive jogwheel. Use the jogwheel to scratch (if Vinyl mode is selected) or pitch bend. The Jogwheel also offers Loop In and Loop Out point adjustment (see further down in Loops keys)
Hold SHIFT and then use the Jogwheel to fast search through the track.
The LEDs around the jogwheel will get the color of the deck when track is playing out live and will blink when track is neat it's end. The Wheel Display will show the Album Art of the loaded track and 2 led rings will indicate the needle/rotation position and the slip mode position (when enabled)
- KEYLOCK. Press this button to "lock" the track's pitch to its original key. The track's tempo will remain at the speed designated by the Pitch Fader.
Hold this button for more than 1 second to match deck's key with the key value of the opposite deck
Hold SHIFT down and then use this button to reset the key of the track to it's original value
- PITCH. Adjust the track's playback speed (tempo). When pitch is at the middle position (track is playing at its original speed), the white center LED will be lit.
When the green-arrow LEDs are lit, the pitch fader has to be moved to the direction the arrows indicate, in order to catch the pitch value of the deck. This is mostly happening when decks are swapped (via the DECK SELECT buttons) and the pitch value of one deck is different than the other.
Note that this Hardware-takeover is not following the soft-takeover of VirtualDJ, meaning that if SHIFT is pressed, the arrows will not indicate the direction the pitch fader needs to be moved to in order to re-gain pitch control, but the ghost-fader on the GUI will be an aid.
- PITCH BEND. Press and hold these buttons down to temporary speed up/slow down the song while pressed. When released, the track playback will return to the speed designated by the Pitch Fader.
