11.1. Ondersteuning toevoegen voor uw MIDI/HID Controller¶
11.1.1. MIDI Scripting¶
In order to support the advanced features of many MIDI / HID controllers, Mixxx offers what we call MIDI Scripting.
It enables MIDI controls to be mapped to QtScript (aka Javascript/EMCAScript) functions stored in function library files, freeing Mixxx from a one-to-one MIDI mapping ideology. These user-created functions can then do anything desired with the MIDI event info such as have a single controller button simultaneously affect two or more Mixxx properties (“controls”,) adjust incoming control values to work better with Mixxx (scratching,) display a complex LED sequence, or even send messages to text displays on the controller.
For more information, go to http://mixxx.org/wiki/doku.php/midi_scripting .
11.1.2. Controller Wizard¶

Mixxx Controller Wizard - Een besturing koppelen/toewijzen¶
Te doen
Add intro and proofread
Sluit uw controller(s) aan op uw computer
Start Mixxx
Ga naar :menuselectie:`Voorkeuren --> Besturingen` of controllers
Selecteer uw apparaat in de lijst met beschikbare apparaten aan de linkerkant en het rechter deelvenster zal aangepast worden.
Activeer het selectievakje Inschakelen.
Klik op Learning Wizard om het selectiedialoogvenster te openen.
Klik op een willekeurig besturingselement in de Mixxx: term: GUI
Of klik op de knop Kies Besturing en kies er een uit de keuzelijst.
Move a control on your controller to map it. Repeat this as many times as you wish.
Wanneer u klaar bent met het toewijzen van de besturingselementen, klikt u op :guilabel: Done
De Controller Wizard werkt alleen voor: term: MIDI-apparaten. Momenteel kunt u geen modificatietoetsen (shift-toetsen) en plaat-rotaties toewijzen. Gebruik in plaats daarvan: ref: MIDI Scripting <advanced-controller-midiscript>.
11.2. Het maken van een Custom Keyboard Mapping¶
De standaard keyboard mappings zijn gedefinieerd in een tekstbestand dat op de volgende locatie te vinden is:
Linux:
/usr/local/share/mixxx/keyboard/en_US.kbd.cfg
Mac OS X:
/Applications/Mixxx.app/Contents/Resources/keyboard/en_US.kbd.cfg
Windows:
<Mixxx installation directory>\keyboard\en_US.kbd.cfg
Depending on your systems language settings, Mixxx might use a different
file as default, e.g. de_DE.kbd.cfg
for German or es_ES.kbd.cfg
for Spanish.
There are two ways to customize the default Mixxx keyboard mapping:
Edit your system’s default mapping file directly, e.g.
en_US.kbd.cfg
.Copy the default mapping file to the following location:
Linux:
~/.mixxx/Custom.kbd.cfg
Mac OS X:
~/Library/ApplicationSupport/Mixxx/Custom.kbd.cfg
Windows:
%USERPROFILE%\Local Settings\Application Data\Mixxx\Custom.kbd.cfg
Then edit this file and save the changes. On the next startup, Mixxx will check
if Custom.kbd.cfg
is present and load that file instead of the default
mapping file. This has the advantage, that you can always revert back to the
default mapping, just by deleting Custom.kbd.cfg
.
For a list of controls that can be used in a keyboard mapping, see http://www.mixxx.org/wiki/doku.php/mixxxcontrols.
You can download and share custom keyboard mappings in the Mixxx User customizations forums.
11.3. Extra effecten via externe Mixer-modus¶
Mixxx does not have an effects engine yet (work on one is in progress). To hold you over you can use some external tools. Using the external mixer mode you route each deck directly to 3rd party effect hosts.
The following examples are only intended to encourage experimentation, they are no definitive guidance.
11.3.1. Effects via AU Lab on Mac OS X¶

The Au Lab routing for external effects on Mac OS X¶
On Mac OS X there is a pretty simple and free way to give Mixxx access to the collection of AU/VST/MAS plugins that are installed on your system.
Install the free Soundflower, a system extension for inter-application audio routing.
Download AU Lab.app standalone from Apple (you will need an free Apple Developer Login though), go to the Downloads for Developers page and search for “AU Lab” to get it.
In Mixxx
Ga naar
.Selecteer voor Deck 1 het Soundflower 16 apparaat met Kanaal 1-2.
Selecteer voor Deck 2 het Soundflower 16 apparaat met Kanaal 3-4.
Klik op de knop Toepassen.
In AU Lab
Klik op de knop + om een nieuwe configuratie aan te maken.
Add 2 stereo inputs tracks in the Audio Input Tab
Voeg 2 stereo output tracks toe in het Audio Output Tab.
Klik OK
Wijzig het audio-invoerapparaat in Soundflower 16.
Changethe audio output device for example to Built-in Output
Klik Document maken
In the Output 1 channel, select an effect from the drop-down menu, for example Apple > AUCompressor
Het effect zou nu moeten reageren als je een track in Mixxx afspeelt.
11.3.2. Effecten via JACK Rack op GNU/Linux¶

De Jack routering voor externe effecten op GNU/Linux¶
Use Jack to route each deck directly through JACK Rack effect racks, or for more control you can use Ardour (or other DAW) using sends for effects. This gives Mixxx access to the extensive collection of LADSPA plugins.
Make sure the correct multichannel sound card has been selected in Jack (Jack settings visible bottom left). Note that Mixxx possibly labels its Jack ports as “Portaudio”.
11.4. Deleting Your Library¶
The library file is stored in the following places depending on your operating system:
- Windows
The Mixxx library is stored in the
%USERPROFILE%\Local Settings\Application Data\Mixxx\
folder. To delete your library on Windows, delete themixxxdb.sqlite
file in this folder.- Mac OS X
The Mixxx library is stored in the
Library/Application Support/Mixxx
folder in your home directory. To delete your library on Mac OS X type the following command into a terminal:rm ~/Library/Application\ Support/Mixxx/mixxxdb.sqlite
- GNU/Linux
The Mixxx library is stored in the
.mixxx
folder in your home directory. To delete your library on GNU/Linux type the following command into a terminal:rm ~/.mixxx/mixxxdb.sqlite
Waarschuwing
Deleting your library will lose all of your metadata. This includes saved hotcues, loops, comments, ratings, and other library related metadata. Only delete your library if you are fine with losing these.
