Traktor Kontrol S5 — Pitch Faders

One important thing that latest Native Instruments S5, S8 and D2 controllers lack badly is the pitch/tempo fader.

Strange enough! Those faders wouldn’t have occupied much space, but without them users are forced to use the SYNC button, even if they want to beat-match manually.

Luckily, it’s quite easy to re-map deck C and D volume faders to act as pitch!

A little bit of hacking is needed. Find the Mixer.qml file on disk.

  • On Windows: C:\Program Files\Native Instruments\Traktor 2\Resources64\qml\CSI\S5

  • On Mac: /Applications/Native Instruments/Traktor 2/Traktor.app, right click, «Show Package Contents», and then Contents/Resources/qml/CSI/S5

Open it in a text editor, and right before the last closing brace insert the following lines:

  // pitch fader start

  AppProperty { id: hack_aTempo; path: "app.traktor.decks.1.tempo.adjust" }
  AppProperty { id: hack_bTempo; path: "app.traktor.decks.2.tempo.adjust" }

  AppProperty { id: hack_aSync;  path: "app.traktor.decks.1.sync.enabled" }
  AppProperty { id: hack_bSync;  path: "app.traktor.decks.2.sync.enabled" }

  AppProperty {
    path: "app.traktor.mixer.channels.3.volume";
    onValueChanged: {
      if(!hack_aSync.value)
        hack_aTempo.value = 1 - 2 * value;
    }
  }

  AppProperty {
    path: "app.traktor.mixer.channels.4.volume";
    onValueChanged: {
      if(!hack_bSync.value)
        hack_bTempo.value = 1 - 2 * value;
    }
  }

  // pitch fader end

Restart Traktor.

Now, when SYNC is off, volume faders C and D will adjust tempo of decks A and B respectively.

Turn off Snap. Turn off Quantize. Cover BPM and phase indicators with tape stickers. And beat-match by ear as a real DJ!

P.S. It was fun to know that controller mappings are done in JavaScript!

  1. Hey,
    Quick question.
    How did you hack to get to know the values, fields and relevant files?
    Did you find any documentation ?

    Thanks !
