The Numark Mixtrack Pro is functionally identical to the :ref:`Numark Mixtrack <numark-mixtrack>`, but includes a built-in USB audio interface.
This model has been discontinued and was succeeded by the :ref:`Numark Mixtrack Pro 3 <numark-mixtrack-pro-3>`.
.. versionadded:: 1.8.2
.. versionchanged:: 2.5.x
The Mixtrack Pro combines traditional two-deck controls with an integrated sound card for main and headphone outputs.
It is compatible with Mixxx and supports plug-and-play operation on most systems.
- :hwlabel:`OUTPUT 1` (RCA):** Main mix output to speakers or amplifier.
- :hwlabel:`OUTPUT 2` (RCA):** Cue channel for headphone monitoring.
- :hwlabel:`HEADPHONES` (1/4”):** Mirrors the cue channel.
- :hwlabel:`MIC THROUGH` (1/4”):** Mic input directly mixed into the master output (not routed to the computer).
Typical configuration in Mixxx:
- Channels 1–2: Master output (stereo)
- Channels 3–4: Headphones (cue/PFL) (stereo)
:hwlabel:`USB`: Sends and receives control information between the controller and the computer.
:hwlabel:`TREBLE`: Adjusts the high-frequency range of the channel.
:hwlabel:`MID`: Adjusts the mid-frequency range.
Advanced alternative mapping available at :ref:`mapping-settings`.
:hwlabel:`BASS`: Adjusts the low-frequency range.
:hwlabel:`CUE` (round button): "PFL". Sends pre-fader audio to the cue channel for headphone monitoring.
Advanced alternative mapping available at :ref:`mapping-settings`.
:hwlabel:`CUE GAIN`: Adjusts the cue channel volume.
:hwlabel:`CUE MIX`: Blends cue and master signals in the headphone output.
Turn fully left to hear only the cue signal; fully right to hear only the master mix.
:hwlabel:`BROWSE`: Turn and press. Turn the knob to scroll through tracks in the library.
- In File mode (see 9), press to load the highlighted track into the first stopped deck.
- In Folder mode (see 9), scroll library, press to unfold item.
:hwlabel:`BACK`: Toggles the browse knob between folder navigation and track list modes (indicated by the FOLDER or FILE LEDs).
:hwlabel:`LOAD A` / :hwlabel:`LOAD B`: Loads the selected track into Deck 1 (A) or Deck 2 (B).
:hwlabel:`A GAIN` / :hwlabel:`B GAIN` fader: Adjusts the channel volume.
:hwlabel:`MASTER GAIN` fader: Controls the overall output volume.
CROSSFADER: Blends audio between Decks 1 and 2.
JOG WHEEL:
- While stopped: scrubs through the track.
- With :hwlabel:`SCRATCH` mode on: the top surface scratches (supports backspin); the edge nudges rate.
- With :hwlabel:`SCRATCH` mode off: nudges rate while playing.
Advanced alternative mapping available at :ref:`mapping-settings`.
:hwlabel:`SCRATCH`: Toggles Scratch Mode (LED on when active).
:hwlabel:`PLAY / PAUSE`: Starts or pauses playback.
LED on = playing; LED off = stopped.
Advanced alternative mapping available at :ref:`mapping-settings`.
:hwlabel:`STUTTER`: Repositions the BeatGrid for better synchronization.
LED blinks at each beat of the grid.
:hwlabel:`CUE` (rectangular button):
- When paused: sets the cue point.
- When playing: returns to the cue point and pauses.
Hold to play from the cue point temporarily; releasing returns to the cue point.
If :hwlabel:`PLAY` is pressed before releasing, playback continues.
LED blinks on beats during the last 30 seconds of the track.
Avoid setting cue points too close to the end of the track.
:hwlabel:`SYNC`: Matches tempo and phase to the other deck.
If the other deck is stopped, only tempo is synced (not phase).
LED acts as peak indicator.
:hwlabel:`SHIFT` (24) + :hwlabel:`SYNC` : resets pitch to 0%.
RATE FADER: Controls playback speed.
LED lights near 0%.
Soft-takeover prevents sudden jumps when hardware/software values differ.
:hwlabel:`PITCH BEND` (– / +): Operation depends on :ref:`mapping-settings`.
:hwlabel:`KEYLOCK`: preserve key (pitch) on playback speed changes.
HOT CUE BUTTONS (1-3):
Printed as :hwlabel:`EQ KILL`: :hwlabel:`BASS`, :hwlabel:`MID`, :hwlabel:`TREBLE`.
- Unlit: press to assign a hot cue at the current position.
- Lit: press to jump to the stored cue point.
:hwlabel:`SHIFT` (24) + HOTCUE: clears the hot cue.
:hwlabel:`SHIFT`: also printed as :hwlabel:`DELETE`, :hwlabel:`VIEW`, :hwlabel:`TICK`.
- Enables secondary button functions (LED on).
- Deactivates automatically after one use.
Combinations:
- :hwlabel:`SHIFT` + HOTCUE: clears Hotcue.
- :hwlabel:`SHIFT` + :hwlabel:`MANUAL` : toggles Quantize ON/OFF.
- :hwlabel:`SHIFT` + :hwlabel:`RELOOP` : clears active loop (loop_remove).
- :hwlabel:`SHIFT` + :hwlabel:`SYNC` : resets pitch to 0%.
Advanced Alternative Mapping is avaible at :ref:`mapping-settings`.
:hwlabel:`EFFECT`: Toggle current FX on the current channel.
Advanced Alternative Mapping is avaible at :ref:`mapping-settings`.
EFFECT :hwlabel:`SELECT`: Turn to scroll through enabled effects, in Mixxx :menuselection:`Preferences --> Effects --> Visible effects`, and load on-the-fly.
- Press to reset to default the Quick Effect Super knob.
- On the left deck: press, hold, and turn to adjust the Waveform Zoom.
LEFT EFFECT :hwlabel:`CONTROL`: Adjusts the MetaKnob.
RIGHT EFFECT :hwlabel:`CONTROL`: Adjusts Mix (dry/wet) knob for FX.
MODE: Switches between :hwlabel:`AUTO` Loop and :hwlabel:`MANUAL` Loop modes.
Auto Loop Mode (LED off):
- :hwlabel:`1/2`: creates a 1-beat loop or halves loop length.
- :hwlabel:`1 BAR`: creates a 4-beat loop or exits the loop.
- :hwlabel:`2X`: doubles loop length or reloop (exit with OUT button).
Manual Mode (LED on):
:hwlabel:`SHIFT` (24) + MODE: toggles Quantize (recommended for manual looping).
- :hwlabel:`IN`: sets loop start point.
- :hwlabel:`OUT`: sets loop end point and activates loop.
- :hwlabel:`RELOOP`: reactivates last loop or exits current manual loop.
Panic or clear: :hwlabel:`SHIFT` (24) + :hwlabel:`RELOOP`: clears loop (loop_remove).
Advanced alternative mapping available at :ref:`mapping-settings`.
:hwlabel:`MIC GAIN`: Controls the microphone level sent to the main mix.
Check in Mixxx: :menuselection:`Preferences --> Controllers --> MixTrack Pro --> Mapping Settings`.
The following advanced or alternative mappings are available:
Play/Pause performs Brake and Soft Start when “SCRATCH LED” is on. Requires Mixxx ≥ 2.6.
Edit Loop by Touch-Wheel: If Scratch LED is off and a loop is active, touching the wheel top, then rotate forward for starting the editing of Loop-IN or rotate backward for Loop-OUT point.
PITCH BEND buttons: follow options available.
- Rate temp up/down: fine temporarily adjusts playback speed (press and hold).
- Beat jump (Default): beat jump, value by Mixxx. Hold + Wheel for fast moving on track.
- Pitch-Key up/down: changes key of track.
Quick Effect Super knob on MID knob: Enables the Quick-Effect super knob (Filter by default) on the MID knob when this modifier is active.
Options:
- None (disabled)
- CUE (PFL) (default)
- SHIFT (VIEW / TICK / DELETE)
- EFFECT
Scratch Sensibility: default 600.
- The pitch faders on the controller have a very short run, making high-range (+/–10%) adjustments less precise. A ±8% range is recommended.
- Knobs and sliders may need to be moved after Mixxx startup to synchronize hardware and software positions.
- Works on Windows, macOS, and Linux.
- USB Audio Class compliant (no driver required on macOS or Linux).
- Tested with Mixxx 2.5, 2.6 and later.
