Performance Pads
The Numark NS4FX comes with 8 performance pads, that can be used across 8 different performance pad modes in Serato DJ Pro. These consist of:
CUE mode: Press this pad mode button once to select CUE mode. In this mode pads 1-8 trigger Serato DJ Pro Cue points, and if no Cue point is present on that slot/pad, pressing that pad will set a Cue point. Holding down the SHIFT button while pressing a pad will delete the Cue point from the respective pad/slot.
AUTO LOOP mode: Press this pad mode button once to select AUTO LOOP mode. Pads 1-8 trigger an autoloop of variable sizes. Use the loop selection area in the Serato DJ Pro user interface, to influence the 8 available autoloop sizes.
FADER CUTS mode: Trigger fader cuts. This mode is firmware-based and not controlled by Serato DJ Pro - see Numark documentation for more information.
SAMPLE mode: Press this pad mode button to select SAMPLER mode. Press pads 1-8 in this mode to trigger samples loaded into the Serato DJ Pro Sampler. Holding SHIFT while pressing a pad will stop a
currently playing Sampler slot, or load a new sample to the Sampler slot if empty.
PITCH PLAY mode: Hold the SHIFT button and press CUE to select PITCH PLAY mode. In this mode, pads 1-8 play Cue points over a pitch range. This requires the Serato Pitch ‘n Time DJ expansion pack to be activated, see the PITCH PLAY section for more information.
ROLL mode: Hold the SHIFT button and press AUTO LOOP to select ROLL mode. Holding pads 1-8
activate a loop roll of varying sizes (1/8 to 16 beats). Release the pad to exit the Loop Roll.
SLICER mode: Hold the SHIFT button and press FADER CUTS to select SLICER mode In this mode a
specified range (or domain) is divided into eight equal sections, and these eight sliced sections are assigned to the respective performance pads (1-8), and can be triggered by pressing each pad. The domain shifts as the track duration elapses.
SCRATCH BANK mode: Hold the SHIFT button and press SAMPLE to select SCRATCH BANK mode.
Scratch Bank Mode allows you at assign files in your Serato DJ Pro library to a pad. When a pad is
triggered, the file corresponding file will be loaded to deck.
Click the Scratch Banks panel toggle button (pictured below) in the top left-hand corner of the Serato DJ Pro user interface to reveal the Scratch Banks panel.
Here you can click and drag tracks into slots in the Scratch Banks panel, adjust preferences that are remembered when the respective Pad is triggered and loaded to a deck, and eject tracks. You can reveal those preferences (such as start point, Key lock on/off, and Repeat on/off) by toggling between Advanced and Simple view in the Scratch Banks panel, by clicking the toggle button (pictured below).
The left set of pads will load Scratch Bank assigned tracks to Deck 1, and the right set of pads will load assigned tracks to Deck 2. Holding SHIFT on your device, while pressing an assigned/loaded Pad, will reload the previously loaded track to the relevant virtual deck.
Beat Jump
To activate Beat Jump, open the Setup screen, navigate to the DJ preferences tab and turn on “Show Beat Jump Controls”.
When you close the Setup screen, you will see Beat Jump controls underneath the existing Auto Loop values on each deck. Checking this box will turn on Beat Jump features in the deck area and let you control Beat Jump from your supported Serato DJ Pro hardware.
When the Beat Jump option is enabled, performance pad modes AUTO LOOP or ROLL mode (where applicable) will use the bottom row of 4 pads (pads 5-8) as Beat Jump controls. This is designed to mirror the change in the deck Auto Loop area (from 8 Auto Loop sizes to 4 Auto Loop sizes + Beat Jump controls).
Pitch Play
There are 3 key ranges to choose from, and the following tables show the pitched key ranges (in Semitones) while using the 8 performance pads in Pitch Play mode.
The root keypad (0) is always lit white, which will play the cue point at its regular pitch.
Use the Parameter Left & Right buttons to move the Key Range up or down.
In Pitch Play mode, pressing a pad will pitch the currently selected cue point up or down the following ranges:
Up Range: (Up 7 Semitones)
| +4 | +5 | +6 | +7 |
| 0 | +1 | +2 | +3 |
Middle Range: (Up 3/Down 4 Semitones)
| 0 | +1 | +2 | +3 |
| -4 | -3 | -2 | -1 |
Down Range: (Down 7 Semitones)
| -3 | -2 | -1 | 0 |
| -7 | -6 | -5 | -4 |
When Pitch Play mode is first enabled, the middle range is selected. Pitch Play mode will default back to the middle range if a new track is loaded. The selected range is recalled if another pad mode is selected, then
the user switches back to Pitch Play mode.
Pitch Play can only pitch one Cue point at a time. To change the selected Cue, hold the SHIFT button and press a performance pad where the cue point you want to select would be (as shown in the HOT CUE performance pad mode).
While holding SHIFT, press the corresponding performance pad for:
| Cue 1 | Cue 2 | Cue 3 | Cue 4 |
| Cue 5 | Cue 6 | Cue 7 | Cue 8 |
The selected cue point defaults to Cue Point 1 on track load, even if instant doubled. A new cue point will be created if a pad with no cue point is selected. Deleting a cue point is not possible in Pitch Play mode.
NOTE: Pitch Play mode is available once the Pitch 'n Time DJ Expansion Pack has been activated in the Expansions window, under the My Account drop-down. Then ensure Pitch 'n Time DJ is checked in the Expansion Pack tab of the Setup screen.
