Operation
Performance Pad Modes
With the included Serato DJ Lite, the upper row of pads can be used to perform
the functions of the four main pad modes described below: Cue, Auto Loop,
Fader Cuts, and Sample. The bottom four pads are used for Stutter, Previous
Track, Search Backward, and Search Forward functions.
If you would like to use Serato DJ Pro and/or the Serato Pitch ‘n Time DJ
Expansion Pack (sold separately), up to four additional pad modes are
available: Pitch Play, Roll, Slicer, and Scratch Bank.
You can also use all eight performance pads for any of the pad mode functions
listed below.
Cue
In Cue mode, each pad assigns a hot cue point or returns the track to that hot cue point.
To enter Cue mode, press Cue.
To assign a hot cue point, press a pad at the desired point in your track. The
pad will light up when it is assigned (with the corresponding color, if
available).
To jump to a hot cue point, press a lit Pad.
To delete an assigned hot cue point, press Shift and the corresponding pad.
Pitch Play
In Pitch Play mode, each pad plays the track from a hot cue point at a different transposition (adjustable by semitones). The Serato Pitch ‘n Time DJ Expansion Pack (sold separately) must be installed to use this mode. See Cue mode to learn how to assign hot cue points.
To enter Pitch Play Mode, press Cue a second time.
To select which hot cue point to use, press Shift and a dimly lit Pad.
To play the track from the hot cue point, press a lit Pad. Each pad
corresponds to a specific transposition (by semitones), depending on the
current range of transposition (see the diagrams here). The pad with no
transposition (the original pitch) will be lit white. The bottom four pads are
only available with Serato DJ Pro.
Auto Loop
In Auto Loop mode, each pad triggers or releases an auto-loop of a different
length. The software’s loop grid determines the size of the loop.
To enter Auto Loop mode, press Auto Loop.
To set an auto loop, press a pad for the desired loop length
Roll
In Roll mode (Serato DJ Pro only), each pad triggers a momentary loop roll.
Releasing the pad stops the loop roll and resumes normal playback where the
playhead would be if you had not triggered the loop roll (i.e., as if the
track had been playing forward the whole time).
To enter Roll Mode, press Auto Loop a second time.
To trigger a loop roll, press and hold a pad.
Fader Cuts
In Fader Cuts mode, the pads will mute and unmute the deck’s audio signal in a
way that emulates crossfader movements toward that deck.
To enter Fader Cuts mode, press Fader Cuts.
To perform a fader cut, press a pad. The bottom four pads are only available
with Serato DJ Pro.
Slicer
Important: Your track must have a set beatgrid for this mode to work.
In Slicer mode (Serato DJ Pro only), the eight pads represent eight sequential beats—“slices”—in the beatgrid. The currently playing slice is represented by the currently lit pad; the light will “move through the pads” as it progresses through each eight-slice phrase. You can press a pad to play that slice. When you release the pad, the track will resume normal playback from where it would have been if you had never pressed it (i.e., as if the track had been playing forward the whole time).
To enter Slicer mode, press Fader Cuts a second time. The deck will exit
Slicer mode if you load another track to the deck or enable Grid Edit mode.
To play a slice, press the corresponding Pad.
Sampler
In Sampler mode, each pad triggers a sample, which you can assign in the software.
To enter Sample mode, press Sample.
To play a sample, press a pad.
To stop playback, or to load a sample if the slot is empty, press Shift and a
pad.
Scratch Banks
In Scratch Banks mode (Serato DJ Pro only), each pad loads a song to the
selected deck. You can assign the song and set the starting point in the
software. This is useful for preparing and performing with song samples for
scratching.
To enter Scratch Banks Mode, press Sampler a second time.
