In this guide, we break down and perform the instant doubles trick. A popular routine with scratch DJ’s, this trick enables the DJ to create a strong delay effect manually by playing a track half a beat out of time.
Step One – Instant Double
To begin the trick, the same track must be playing at the same time on both decks. Double tapping the LOAD button on the paused deck on most DJ controllers will instant double the playing track. Instant doubles can also be achieved by dragging the playing track from one virtual deck into another.
Step Two – Beat Jump
Once both tracks are playing at the same time, the second deck needs to be playing half a beat behind. To achieve this perfectly in time, the beat jump feature must be used. You may need to adjust the available divisions on the beat jump feature to see the half beat option.
Step Three – Slip Mode
In order to be able to manipulate the second deck and repeat the trick, slip mode must be activated. Slip mode allows the DJ to make changes to the playing track with the song jumping back to where it usually. Some controllers and decks will have dedicated slip mode buttons, if yours doesn’t you can activate it inside the software. Traktor users note that Slip Mode is referred to as FLUX mode.
Step Four – Vinyl Brake
The speed of the brake needs to be changed to replicate that of a vinyl slowing down on a turntable. The brake speed can be changed on some decks directly. To change this setting in Serato head to DJ Preferences. Rekordbox users will find this option in Preferences>Controller>Deck. Set the brake speed to stop roughly within one beat.
Step Five – Optional Reverb
To enhance the sound of the spin backs and vinyl brakes, a reverb can be applied.
Step Six – Crossfader Timing
Finally, we need to swap between the two tracks just at the right time. For maximum effect, the tracks should be swapped on the off beat. The off beat is the AND when we count “1 AND 2 AND 3 AND 4”. You can see the off beat in the below wave form as the blue cymbal hits.
Practice, Practice, Practice!
Now you’ve learnt all the steps of this routine, it’s time to start practicing. Remember to perfect the off beat timing, it’s key to transition between the two tracks at just the right time. Once you’ve mastered this example why not try changing it up, different effects and vinyl break speeds can help give this trick a completely different sound!

The trancifier is a hidden feature baked into the code of Serato DJ that has existed since Serato Scratch Live! The trancifier once applied loops a track, halving the loop automatically until only a fine note sound is created. This trick creates incredible build ups and can be combined with other effects for amazing transitions!
