Interfacing to Mixxx via MIDI (Linux)
This tutorial explains how to drive QLC+ via MIDI from Mixxx. Mixxx is an open source DJ application, running on Windows, Mac OSX and Linux. The light effects are geared to a disco setup and we will use the beat detection of Mixxx to drive light effects synchronized with music.
The instructions were tested on Linux, but Windows or Mac OSX should be similar.
Prepare and configure Mixxx
We need Mixxx to send information about the music via MIDI to QLC+. For this capability we need a plugin script in Mixxx which sends the information as MIDI events.

- Install Mixx, I used version 1.11
- Install the 'MIDI_for_light' script from this (Mixxx forum thread)The script files (xms + js) must be installed in /usr/share/mixxx/controllers.
- Run Mixxx in developer mode with the command 'mixxx --developer'.This is necessary because Mixxx hides the 'Midi Through' interface but we need it.
- Start Mixxx, go to 'Options - Preferences - Controllers', select 'Midi Through', enable it and load the Preset 'MIDI for light' from the list.
This will enable the sending of Midi events. You can now run a midi monitor, like 'kmidimon', connect it to the 'Midi Through' device and look at the all the events. Be careful, Mixxx sends 40 events 25 times per second. It to my kmdimon only a minute or two to hang because of overload.
Configure QLC+
Now we have Mixxx sending us lots of interesting data and want QLC+ to do something with it.
Install QLC+, I used version 4.8.2
Define your fixtures and functions as usual
In the 'Inputs/Outputs' panel, select the 'MIDI Through' device as input
Select the MIDI Through device and click on plugin configuration and configure the 'Midi Through' device. Then:
- Set the 'Midi' Channel to 1
- Set the 'Mode' to 'Note Velocity'
- Leave the 'Init Message' on 'None'
- Push EXIT button.
In the Profile tab of the 'Inputs/Outputs' screen, add a new Input Profile. I called it 'Mixxx' and model 'MIDI'.
Here we need to add a Channel for each MIDI message we expect from Mixxx. The list of Midi messages is documented in the file 'VU-Meter_Info.txt' you got with the Mixxx plugin script.- First we add a channel for the BPM info (not documented in the file).
Add a channel, name it 'BPM', Type is 'Button', Midi channel is '1', Message is 'Note On/Off', Parameter is 101. - Then we add all channels with the volume information
Add a channel, name it 'Volume - absolute', Type is 'Slider', Midi channel is '1', Message is 'Note On/Off', Parameter is 101. - Repeat this for all channels you find interesting
The relative volume channels can give interesting light effects, the absolute volume is less interesting
- First we add a channel for the BPM info (not documented in the file).
Now go to your Virtual Console and start using the MIDI signals. Here two examples:
- Configure the BPM to advance a cue list on each beat
In your Cue list, in the 'Next Cue' tab, click on 'Choose', expand the 'Mixxx MIDI' line and pick BPM from the list. Your cue list will now advance with the beat of the music, as determined by the Mixxx beat detection. - Make a lamp light up with the Volume of the music (VU meter)
Configure a Slider, on the 'General' tab, under 'External input' click on 'Choose' and select a channel of your choosing, for example 'Volume absolute'. The selected Fixture will now light up with the volume of the music, like a giant VU meter.
- Configure the BPM to advance a cue list on each beat
Mixxx Pricing and Features
Mixxx is an open source, free-to-use DJ mixing software, making it the perfect choice for starting DJ aspirants or those who simply cannot afford to buy a mixing program with their limited resources. It is available for Windows, Mac OS X, Ubuntu, and Linux systems.
With simple drag and drop gestures, you can start editing a track with Mixxx. You have four decks on your screen, each one fitted with a scratchable, scrollable waveform with markings on beat and cue points. Notably, the interface has improved from the first version of the software. Now, you can resize the skins as you want, you can show and hide element as needed, or change the skins and configure the layout, as the package also includes 3 designer skins to choose from. While that may not be a lot, it certainly is a step in the right direction in giving users more personalization options.
Syncing multiple tracks prove to be a breeze with Mixxx’s master sync feature as the beats of tracks stay locked even if you change their speed. If you happen to find a specific portion that you would like to loop, you can do with the beat looping button, allowing you to loop a 4, 8, or 16 beat segment. You can also trigger short loops and reverse playback effects to keep the rhythm going.
One thing you will notice is that the effects within the program are quite limited, offering only flanger, Moog 4-pole ladder filter, Echo, Reverb, and BitCrusher. This, however, may still be a work in progress, especially since the previous version only allowed for one effect to be applied to any deck. You can now set up a chain group of effects in up to 4 FX units. Izotope vinyl download vst. You can also enjoy tweaking multiple parameters at once with a single knob, with assignable affected effects.
Recording and broadcasting your mixes is an easy task to do as well, and you can store your tracks in lossless WAV format or compressed OGG Vorbis form. You can share your creations via Shoutcast or Icecast, or through MP3 streaming, although by default, this option is disabled due to licensing restrictions. Enabling this option requires you to download a LAME binary and copying some files to the Mixxx folder. If this sounds complicated, don’t worry; you can read a full step-by-step procedure of the process over at their website, complete with the link for the needed download.
Mixxx Customer Support
Mixxx has a dedicated community support center where you can find FAQs, user manuals, forums, developer mailing list, IRC channel, which can be used to ask for assistance, and to chat with developers and fellow Djs, and a bug tracker, in case you encounter any within the program.

As of this writing, a handful of timecodes are supported as well, such as Serato CV02, Traktor Scratch MK1, and MixVibes DVS V2, with absolute positioning, needle cueing, and end of record detection. It is the only software to offer this feature across different operating systems, namely Windows, Mac OS X, and Linux, so you can bet that you will be using a well-developed program.
