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. It is compatible with Mixxx since 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 Sound Card 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.
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.
There are some user configurable options for this mapping. To change the options, open the .js file in your user controller mapping folder 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.
The controls for library browsing can be found in the center top of the controller.
|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:
Press the deck button. It lights when deck 3-4 is active.
Between the decks the usual faders, crossfader and EQ knobs can be found. A filter knob is also available.
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.
When a deck is paused, the jogwheel allows you to browse through a track. If you want to browse faster, hold shift while using the jogwheel.
When a deck is playing, using the jogwheel allows you to temporarily change the tempo of the playing track. Again, holding shift exaggerates this effect.
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.
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.
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. Refer to the Mixxx manual for how to use master sync.
Additional functions can be accessed by holding shift
|Shift + play||Plays the track in reverse and enables slipping (see slip mode)|
|Shift + cue||Brakes the track as if the power of the motor on a turntable was turned off|
|Shift + sync||Enables quantize mode (this makes most actions, e.g. pressing play or setting the cue point, fall to the nearest beat)|
In hot cue mode the upper row of pads control the hotcues. Pressing a pad that is not lit sets a hotcue. Pressing a pad that is lit makes the track jump and play from that hotcue. Pressing a pad while holding shift deletes that hotcue.
You can control a set of 4 more hotcues by pressing shift + hot cue. The hot cue button will start blinking. The pads will behave in the same way, but controlling hotcues 5 to 8.
Pressing the pads in auto loop mode will make loops of a specific length measured in beats.
|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|
|Shift + pad 4||enable loop, jump to loop in marker, and stop playback|
This mode allows you to set loops different from the fixed lengths of beats in auto loop mode.
|Pad 1||Set loop in|
|Pad 2||Set loop out|
|Pad 3||Toggles loop|
|Pad 4||Halve loop length|
|Shift + pad 4||Double loop length|
|Shift + pad 1||Move loop one beat backward|
|Shift + pad 2||Move loop one beat forward|
In sampler mode the sampler can be controlled. To load a file into a sampler, first press the sampler button while holding shift, so that the sampler button starts blinking. Now pressing a pad will load the currently highlighted track on the library into the corresponding sampler. Pressing a pad while holding shift will eject the sample.
To play samples, press the sampler button without holding shift (it should not blink). Pressing a pad will start playing the corresponding sample, pressing a pad while holding shift will stop it.
By pressing the auto loop button while holding shift (it should start blinking) you can make loop rolls. This mode combines auto loops with slip mode. The pads will start a loop in the current position with a determinate beat length while simultaneously enabling slip mode, so that when releasing the pad the track will continue playing as if the loop never happened.
|Pad 1||1/16th beat loop roll|
|Pad 2||1/8th beat loop roll|
|Pad 3||1/4th beat loop roll|
|Pad 4||1/2 beat loop roll|
|Shift + pad 1||1 beat loop roll|
|Shift + pad 2||2 beat loop roll|
|Shift + pad 3||4 beat loop roll|
|Shift + pad 4||8 beat loop roll|
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|
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.
Start/stop Auto DJ: Shift + DECK 4. If enabled in the user options enabled, the level meter LEDs twinkle.
Skip Track: Shift + DECK 3
By moving a channel fader up from the very bottom while holding shift when a deck is paused, the deck will start playing. Moving the fader back to the bottom without releasing shift stops the deck and moves it back to its original position.
