Pioneer DDJ-SB2

The Pioneer DDJ-SB2 is an all-in-one USB MIDI controller with a built in sound card. It has controls for 2 decks that can be toggled between decks to play with 4 decks.

New in version 2.0.


The sound card has 2 RCA jacks for the main output. There are two headphone jacks, one small (1/8“) and one large (1/4”) connector (each jack plays the same channels, they cannot be used for independent signals). There is a 1/4» microphone input with an adjustable gain knob. The microphone input is mixed directly with the main RCA outputs in hardware. It is not available to the computer, so cannot record or broadcast with the microphone input on the controller. You could use the controller with a separate USB audio interface that has a microphone input for that purpose. The microphone preamplifier is very noisy, so it is recommended to keep the microphone gain knob all the way down when not using a microphone, otherwise there will be noise added to the main RCA outputs.


Pioneer has a driver for Windows versions 7 and newer. Select the ASIO sound API in Mixxx’s Sound Hardware Preferences.

Mac OS X & Linux

The DDJ-SB2 is a USB class compliant MIDI and audio device, so it works with Mac OS X and Linux without any special drivers.

User Options

There are some user configurable options for this mapping. To change the options, open the .js file in your controller for your Pioneer DDJ-SB2 with a text editor such as KWrite or GEdit on GNU/Linux, Notepad on Windows, or TextEdit on Mac OS X.

  • blinkingSync: If true the sync button blinks with the beat, if false led is lit when sync is enabled.

  • invertVinylSlipButton: If true, the vinyl button activates slip. Vinyl mode is then activated by using shift. Allows toggling slip faster, but is counterintuitive.

  • jogwheelSensivity: Sets the jogwheels sensitivity. 1 is default, 2 is twice as sensitive, 0.5 is half as sensitive.

  • jogwheelShiftMultiplier: Sets how much more sensitive the jogwheels get when holding shift. Set to 1 to disable jogwheel sensitivity increase when holding shift.

  • speedRateToNormalTime: Time per step (in ms) for pitch speed fade to normal

  • showVumeterMaster: If true Level-Meter shows VU-Master left & right. If false shows level of channel: 1/3 2/4 (depending active deck)

  • cutVumeter: Cut’s Level-Meter low and expand upper. Fore example, at 0.5 only signals greater 50% show on the meter, expanded to full range

  • twinkleVumeterAutodjOn: If true VU-Level twinkle if AutoDJ is ON.

  • jumpPreviewEnabled: If true, when releasing the browser knob, the preview deck jumps forward to “position”.

  • jumpPreviewPosition: The place in the track to jump to, on a scale from 0 (beginning of track) to 1 (end of track).


Library browsing




Rotary knob

Track selection

Load buttons

Loads currently highlighted track to the corresponding deck

Pushing rotary knob

Loads currently highlighted track to the preview deck and plays it

Pushing rotary knob again without rotate

Stop the preview deck

Shift + rotary knob

Library section selection (scroll through left pane of library)

Shift + pushing rotary knob

Toggle expanding library section

Pushing the rotary knob to start playing a track in the preview deck then releasing it jumps forward in the preview deck. This behavior can be disabled in the mapping’s user options and the place in the track it jumps to can also be configured.

Addition functions not belonging to library:

  • Shift & load left -> toggle effects view in/out

  • Shift & load right -> toggle sampler view in/out

Switching between decks

Press the deck button. It lights when deck 3-4 is active.

Volume, equalizers & filters


Knobs are available for the master and headphones level. These control the controller’s built in sound card; they do not control the software gains in Mixxx, so moving them does not move the master and headphone gain knobs on screen.

The filter fade button changes the crossfader from fading the volumes between decks to using filters to fade between decks.

The TRIM knob controls the deck’s gain.

Jogwheels, tempo & vinyl mode



The tempo slider allows changing the tempo of each deck. This normally changes the pitch of a track, but you can make the pitch stay constant by pressing the “key lock / tempo range” button. Additionally, with shift, the “key lock / tempo range” will fade the tempo slowly to 0. The fading speed can be customized with the speedRateToNormalTime mapping option.

Vinyl mode makes the jogwheels emulate the way turntables work. Vinyl mode can be toggled by pressing the “vinyl / slip” button. Touching the outer plastic ring of the jogwheel will temporarily change the tempo like when vinyl mode is off. Touching the metal disc simulates touching the vinyl record, so just putting your hand on it will stop the “vinyl”. You can scratch in a similar way as with turntables in vinyl mode.

Slip mode

By pressing shift + “vinyl / slip” you can toggle slip mode. When entering slip mode, Mixxx remembers what point exactly of the track should be playing even if, for example, you scratch or make a loop. When you press shift + slip again, Mixxx will jump back to that point.

Pads - lower row

The play and cue pads should be self-explaining. The sync pad toggles master sync for a deck, which tries to beatmatch the deck with the others, and also syncs the tempo between them, even when the tempo of one deck is changed.

Additional functions can be accessed by holding shift



Shift + play


Shift + cue


Shift + sync

Enables quantize mode (this makes most actions, e.g. pressing play or setting the cue point, fall to the nearest beat)

Pads - hot cue mode



Pads - auto loop mode




Pad 1

set a loop of the selected number of beats

Pad 2

halve the selected loop length

Pad 3

double the selected loop length

Pad 4

reloop (reactivate a pre-existing loop)

Shift + pad 1

set a rolling loop of the selected number of beats

Shift + pad 2

beatjump backwards by the beatjump size, or move the loop backwards by the beatjump size if the loop is enabled

Shift + pad 3

beatjump forwards by the beatjump size, or move the loop forwards by the beatjump size if the loop is enabled

enable loop, jump to loop in marker, and stop playback

Pads - manual loop mode

This mode allows you to set loops different from the fixed lengths of beats in auto loop mode.

Pads - kill (shift + manual loop)

By pressing the manual loop button while holding shift (it should start blinking) you can make the pads behave as EQ kill switches.



Pad 1

Kill low

Pad 2

Kill mid

Pad 3

Kill high

Pad 4



The knob controls the dry/wet knob of the whole effect chain when no effect is focused. When an effect is focused, the knob controls the metaknob of the focused effect. Focus an effect by pressing one of the effect buttons. To switch the controller’s knob back to manipulating the dry/wet knob, unfocus by pressing the button of the focused effect again.

Press and hold an effect button to toggle the enable switch for that effect. The enable switches for each effect are not shown on the controller’s LEDs, so you need to look at the screen to check whether an effect is on. All effects are off when Mixxx starts.

Use shift and the mixer knobs to control the parameters of the focused effect. The trim knob controls parameter 1, the equalizer knobs control parameters 2-4, and the filter knob controls parameter 5.

The DDJ-SB2 does not have enough buttons to control assigning effect units to different decks. You may want to set up a custom keyboard mapping to have easy access to those switches. Otherwise, you can use your mouse to click the buttons on screen.

Auto DJ

Start/stop Auto DJ: Shift + DECK 4. If enabled in the user options enabled, the level meter LEDs twinkle.
