Pioneer DDJ-FLX4 (schematic view)
The Pioneer DDJ-FLX4 is a 2 deck USB controller with an integrated audio interface designed for rekordbox and Serato.
The mapping has been created on Firmware version 1.02
The Pioneer DDJ-FLX4 is USB audio and MIDI class compliant and works with Linux, Windows, and macOS without needing to install any drivers.
Configure Mixxx's :ref:`sound hardware settings <preferences-sound-hardware>` as follows:
| Output | Channel |
|---|---|
| Master | 1-2 |
| Headphones | 3-4 |
Note
It is not possible to record or broadcast input sent from the 1/4" unbalanced TS microphone jack on the controller, as it is not routed back to the computer and cannot be configured as an input device.
The schematic drawings used here can be referenced in the manufacturer's manual on the given page number.

| 12 | :hwlabel:`TEMPO` slider | Adjust playback speed. |
| 13 | Performance pads | Functionality differs depending on the pad mode selected by 8-11. |
| 14 | :hwlabel:`PLAY/PAUSE` | Play/pauses a track). |
| 15 | :hwlabel:`CUE` | Behavior depends on the :ref:`cue mode <interface-cue-modes>`. |
| 16 | :hwlabel:`SHIFT` | Used to access secondary functiones of other buttons while being pressed. |
The pad mode buttons change between different modes in which the performance pads operate. The main pad modes described below are similar to those found in rekordbox.
Note
The secondary pad modes described in the manufacturer's manual (:hwlabel:`KEYBOARD` :hwlabel:`PAD FX1` :hwlabel:`PAD FX2` and :hwlabel:`KEYSHIFT`) are not currently implemented by this mapping.
Bookmark positions in the track and jump to them.
Pioneer DDJ-FLX4 (hot cue pads)
| No. | Control | Function |
|---|---|---|
| 1-8 | Pad (unlit) | Save current position as hot cue. |
| 1-8 | Pad (lit) | Jump to hot cue. If the track is stopped, holding the pad will preview the hot cue until the pad is released. |
| 1-8 | :hwlabel:`SHIFT` + Pad (lit) | Clear hot cue. |
Press a pad to enable a loop from the current position. Press the pad again to disable the loop. The size of the loop is assigned to the pads as follows:
| 1/4 beat | 1/2 beat | 1 beat | 2 beats |
| 4 beats | 8 beats | 16 beats | 32 beats |
Press a pad to jump forwards or backwards by the number of beats assigned to the pads below.
Press :hwlabel:`SHIFT` + pad 7 to decrease or :hwlabel:`SHIFT` + pad 8 to increase the jump values by a factor of 16.
| 1 beat back | 1 beat forward | 2 beats back | 2 beats forward |
| 4 beats back | 4 beats forward | 8 beats back | 8 beats forward |

| 6 | :hwlabel:`SHIFT` + :hwlabel:`ON/OFF` | Disables all effects in the chain and kills the wet/dry mix |
Note
Soft takeover is enabled on the :hwlabel:`LEVEL/DEPTH` knob to prevent sudden changes to the wet/dry mix or effect metaknob when changing between the two.
