Performance Pads
The Pioneer DJ DDJ-FLX4 comes with 8 performance pads that can be used across 8 different
performance pad modes.
The first 4 modes can be triggered by pressing the performance pad mode button of the same name once and consist of:
HOT CUE 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 the SHIFT button while pressing a populated pad will delete the Cue point from the respective pad/slot.
PAD FX 1 mode: Pad FX 1 mode allows the user to trigger quick and powerful preconfigured FX in an intuitive manner. Pads 1-4 can be pressed and held to apply FX, whereas pressing pads 5-8 toggle FX that are applied until the pad is pressed again (toggle). Pads 1-4 consist of Echo, Flanger, Reverb, and Repeater, while pads 5-8 consist of Echo Out, Backspin, Braker, and Rollout.
BEAT JUMP mode: Press pads 1 and 4 perform Beat Jump left & right respectively, while pads 2 & 3 halve and double the Beat Jump size. Pad 5 loads the previous track, pads 6 & 7 perform rewind or fast-forward transport functions, and pad 8 censors the playing track. Holding SHIFT while pressing pad 8 toggles reverse playback.
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 into it if it is empty.
The second 4 modes are as follows:
PITCH PLAY mode: Press the HOT CUE mode button while holding SHIFT to enter Pitch Play mode. Pads 1-8 play Cue points over variable pitch ranges in this mode.
See the ‘Pitch Play’ section for more information.
NOTE: Pitch Play mode requires the Serato Pitch ‘n’ Time DJ expansion pack to be activated & enabled.
LOOP ROLL mode: Press the PAD FX1 mode button while holding SHIFT to enter Loop Roll mode. Holding Pads 1-8 activates a loop roll of varying sizes. Release the pad to exit the Loop Roll.
AUTO LOOP mode: Press the BEAT JUMP mode button while holding SHIFT to enter Auto Loop mode. In this mode, pads 1-8 trigger an Auto Loop of varying sizes. Press the same pad for a second time to exit an Auto Loop.

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 (only available on certain devices) 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.
