Traktor Global MIDI Control: Control Multiple MIDI Devices With One Controller

Traktor Pro 2.8 brought support for the Kontrol D2, as well as several other features. Quietly included in that update were mapping options for “MIDI Controls”, which allows Traktor to read MIDI signals from one device and parse this input as a MIDI signal for another device. Essentially, this feature allows you to control not only Traktor, but also external VSTs, DAWs, and MIDI hardware with one device, and also allows you to integrate those controls with Traktor’s built-in modifiers and environment states. Read more to see how this powerful mapping feature can seamlessly extend your live performance outside the bounds of Traktor.

What do the Global MIDI Controls do?

The core functionality of the ‘MIDI Controls’ is to read the button, fader, or knob states from one MIDI device and pass those states to another MIDI device. Although the feature was designed for the customization of the S8 and D2 “Performance Area” knobs, buttons, and faders, this feature works with any MIDI device.


The MIDI Controls, like many other inputs in Traktor, can be interpreted as special modifiers taken from the state (values) of the controls assigned by the user on the In-Port.

Matching MIDI Control outputs send the corresponding values of the assigned inputs as MIDI signals on the Out-Port. As of Traktor Pro 2.9.0, there are 8 knobs, 8 faders, and 8 buttons which may be assigned per mapping scheme. Like most other Traktor key/MIDI mapping functions, the MIDI Controls can be programmed to interact with modifiers; this allows you to fit these mappings with Traktor-mapped shift buttons or mapping page functionality.

What can Global MIDI Controls be used for?

Unlike most Traktor features which can manipulate audio from a deck or change the basic operation of the software, this addition does not directly affect anything within Traktor. Instead, this feature can be used to extend the functionality of your MIDI controller outside of Traktor’s functionality.

This essentially allows you to control any MIDI-compatible device, software or plugin from a MIDI control surface already connected to Traktor and integrated with the powerful mapping assignment features Traktor offers.

Many synths, drum machines, sequencers, and other hardware include not only the ability to send MIDI output, but also the ability to be controlled with MIDI input. For example, the Roland TR-8’s internal effects can be controlled with external MIDI control signals.

One long-requested feature for Traktor that has yet to be implemented is the ability to natively use VST plugins. However, in combination with a virtual MIDI port (such as the built in IAC Driver on Mac OS X, or loopmidi for Windows), it is possible to control a VST with the MIDI signals passed by Traktor. This would allow you to use the same controller to control Traktor and your VST plug-ins.

One reason to use Traktor to repeat the signal, rather than duplicating the MIDI input signals with a utility, is to take advantage of Traktor’s modifiers so you can, for example, create a page of VST controls on a MIDI Fighter, create an instant-gratification mapping, or change a control’s functionality with a shift button.

Here’s an example of a “dual mapping” with Traktor and a Maschine Micro with the Maschine VST. The blue Maschine pads are mapped to Traktor cue points, while the orange Maschine pads are mapped using the Global MIDI Controls to the Maschine plugin.

Here is another example, where some previously unused knobs and buttons of a Numark 4TRAK have been assigned to Massive, configured to generate and apply effects to white noise, which can be very useful in your sets. The leftmost button has been assigned to turning the white noise generator on and off, while the four knobs (from left to right) control the white noise amplitude, color, reverb, and master volume.

Another use for the Global MIDI Controls is to control a DAW such as Ableton Live. Using a tool such as Soundflower for Mac or Virtual Audio Cable for Windows, you could route audio to and from Traktor and your preferred DAW, and use the Global MIDI Controls to trigger MIDI loops, VST Effects, and launch samples in a DAW using the same device connected to Traktor. Again, this is powerful as you can use Traktor’s mapping modifier variables alongside the Global MIDI Controls, allowing you to, for example, create a page of Ableton sample triggers for a MIDI Fighter which could also control loop rolls and instant gratification effects in Traktor.

How to map the Global MIDI Controls

In order to use this feature, you will require the following software:

  • Traktor 2.8.0 or newer – The Global MIDI Controls feature was added with 2.8.0 with the launch of the Kontrol D2.
  • Virtual MIDI Ports – If you are passing MIDI signals from Traktor to a DAW or a VST, instead of to an external MIDI device, you may need to create virtual MIDI ports. On Mac OS X, the IAC Driver, already included as part of the operating system, is able to create virtual MIDI buses. On Windows, you’ll need a third-party utility such as loopMIDI to create virtual MIDI buses.

Due to the wide range of possible software and hardware you’ll be able to control, it is very likely you will need to experiment with the note and CC signals Traktor outputs. Here’s a general guide to assigning the Global MIDI Controls:

  1. Create the Virtual MIDI ports. This step is necessary for sending signals to a DAW or a VST. It may not be necessary if you are sending signals to an external MIDI device which already has a MIDI input port that Traktor can send the MIDI signals directly to. Make sure your MIDI port shows up under the devices list in Traktor.
  2. Create a new mapping, or modify your controller’s current mapping. If you are planning to use modifiers to send MIDI signals to another device or software, you will need to modify your controller’s base mapping instead. Set the In-Port to the device you wish to use as the control device, and the Out-Port to ‘All Ports’. It is necessary to send signals to all ports to retain any MIDI-Output functionality of the controller (Such as lighting) but still send the MIDI signals through the virtual MIDI port.

  3. Assign the knob, fader, and button inputs in Traktor. This part is pretty straight forward. Create a new “MIDI Control” assignment for every knob, button, and fader you wish to control another device with. The assignment is found in the “Global” section of the “Add In…” drop-down menu. If you are new to Traktor mapping, it would be handy to refer to this DJ TechTools guide on building a basic MIDI mapping with Traktor.Note that Traktor does not yet have toggle functionality enabled for the button mapping.If you wish to create a toggle, instead of using a Global MIDI Control assignment, you may need to assign toggle buttons to a modifier. The output you send would also need to be based on a modifier output rather than a Global MIDI Control.
  4. Assign the knob, fader, and button outputs in Traktor. You may assign the outputs to any note or CC output. It may be easier to simply assign the output to the same CC or note as the input (by using the mapping “Learn”) Since Traktor is broadcasting the MIDI output on all ports, it is important to make sure the outputs you have assigned do not interfere with any other device. You can test this out by connecting all of your gear to Traktor and checking if using any knobs, faders, or buttons causes peculiar output or behavior on any of your gear.After you have assigned the outputs, you should test the signals with your virtual MIDI port utility. IAC and loopMIDI allow you to see if data is being passed through the virtual MIDI port.
  5. Configure the MIDI-input device and assign the input control in your VST/DAW/MIDI-device. You’ll want whatever device or software you are controlling to read only from your virtual MIDI port, as well as any additional devices that may control it. Most software allows you to map various parameters to any MIDI control specified. Refer to your software’s user guide to figure out how to assign controls. If you have configured the mapping assignments and virtual MIDI ports properly, the MIDI signals should seamlessly pass through the Traktor and MIDI-learning the controls should work the same as natively assigning parameters to any control surface.

Endless Possibilities

Despite being a very unannounced feature, the Traktor Global MIDI Control mapping assignments are potentially one of the most powerful mapping features Traktor has to offer. With the right combination of MIDI mappings and audio routing, the possibilities for integrating Traktor with performance software and devices are endless. This feature could be a game-changer for live Traktor performance.
