Pioneer DDJ-SB MIDI Mapping for Mixxx

** IMPORTANT NOTICE ***

There is a new fork available for this project: https://github.com/jardiacaj/mixxx

I recommend installing this one and start testing this and give feedback to jardiacaj on github

This version has way more functionality then my version. Check it, test it. Thanks

Description

This is a basic mapping for Mixxx for the Pioneer DDJ-SB (2 decks). The code is based on / forked from hrudham's project: Mixxx-Pioneer-DDJ-SR (https://github.com/hrudham/Mixxx-Pioneer-DDJ-SR). I've used the same methods but stripped it a bit so it works for my DDJ-SB and also so the code is understandable to me. I like to understand what I implement. So I might have deleted some cool functionality from the original project ...

• It requires v1.11. Certain functionality will NOT work in previous versions.
• Forum Thread on mixxx.org -> http://www.mixxx.org/forums/viewtopic.php?f=6&t=6886

How do I use it?

If you just want to get your controller working with with Mixxx without bothering about the details much, then do the following:

1. Download the following two files:
   • [PIONEER-DDJ-SB.midi.xml] (https://github.com/wingcom/Mixxx-Pioneer-DDJ-SB/blob/master/Pioneer-DDJ-SB.midi.xml)
   • [PIONEER-DDJ-SB-scripts.js] (https://github.com/wingcom/Mixxx-Pioneer-DDJ-SB/blob/master/Pioneer-DDJ-SB-scripts.js)
2. Copy these to the [Mixxx Directory]/controllers folder. This will probably be one of the following locations:
   • Windows: C:\Program Files\Mixxx\controllers
   • Linux: /usr/share/mixxx/controllers or /usr/local/share/mixxx/controllers
   • OS X: /Applications/Mixxx.app/Contents/Resources/controllers/
3. Make sure your Pioneer DDJ-SB is plugged in and turned on
4. Open (or restart) Mixxx, and enjoy using your (semi-functional) controller

What's implemented?

I've only implemented what I need and "know of" for now...

• General
  • Cross-fader
  • Volume Control Channel, Master and Headphones
  • Manual Filtering High, Mid and Low
  • Playlist browsing
    • Back : switches between Tracklist and Sidebar
    • RoatrySelector : browses through the Tracklist of the Sidebar
    • RotarySelectorClick : Expands or Collapses the Sidebar item
    • Load : loads the selected track in the Left or Right deck
  • Sampler Control
    • Push : Starts playing the sample from start
    • Shift-Push : Stop playing the sample
  • Pitch Control
    • Inverted. With my current skin I can not get this to work as intended even if I change the setting

• Deck Controls

  • Play / Pause / Cue

    • Cue: Sets the Cuepoint when not playing, Jumps to Cuepoint when playing

  • Vinyl Mode

  • Keylock

  • Precue'ing

  • Hotcue Control (4 can be set)

    • Push: Sets the hotcue and lights up the LED of the pushed button.
    • Push again: Turn of the hotcue point

  • Autoloop Control

    • 4 Autoloops can be set (no shift use on Performance Pads yet) on: 1 beat / 2 beats / 4 beats and 8 beats
    • If you want other beatloops you need to change the xml and the LoopInterval Enum in the Init() function

  • Manual loop Control (still buggy)

    • In : Sets in point
    • Out : Sets out point
    • Exit : Not working yet. Pretty annoying :)
    • 1/2 : Cut loop in half

  • Jogwheel Control When playing in normal mode, only touching/turning the side will result in pichbend. All other interactions are disabled in this mode.

  • NORMAL MODE (when playing)

    • Pitchbend using the side of the Jogwheel

  • NORMAL MODE (when not playing)

    • Scratching / Seeking when turning the Jogwheel surface I've switched this to Scratchmode, it makes seeking by using the jogwheels quicker.

  For the next mode I've tried to make the DDJ-SB behave like a vinyl as much as I understand of it.

  • VINYL MODE (when playing)
    • Brakes when touching the Jogwheel surface, Starts again when releasing.
    • Pitchbend using the side of the Jogwheel
  • VINYL MODE (when not playing)
    • Scratching / Seeking when turning the Jogwheel surface

What's missing?

• Shift Functions of the Performance Pads
• Manuel loop bug
• Reversed Pitch Control
• Channel Filters
• Crossfader Automatic Filter
• Effects (Not available in Mixxx I think?)
• Decks 3 and 4

I will definitly fix the Manual Loop bug and as I go along and need more stuff I might implement the exta functions (Performance Pads Shifts) same goes with deck 3/4 which, atm, I don't need those.

If I stumble upon good code to do the filtering, I will probably implement that too. Suggestions are welcome.
