11. Opcions avançades

11.1. Afegiu suport per a la vostra controladora MIDI/HID

11.1.1. Scripts MIDI

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. Assistent d’aprenentatge

Assistent d'aprenentatge del Mixxx - Assignant un control

Assistent d’aprenentatge del Mixxx - Assignant un control


Add intro and proofread

  1. Connecteu la(les) controladora(es) a l’ordinador

  2. Inicieu el Mixxx

  3. Aneu a Preferències ‣ Controladores

  4. Seleccioneu el dispositiu de la llista de dispositius disponibles de l’esquerra, i canviarà la informació al panell dret

  5. Marqueu la opció Activat

  6. Feu clic a Assistent d’aprenentatge per a obrir la finestra de selecció

  7. Feu clic a qualsevol control de la interfície

  8. També podeu fer clic al botó Trieu el control i trieu-ne un de la llista

  9. Move a control on your controller to map it. Repeat this as many times as you wish.

  10. Un cop hagueu acabat d’assignar els controls, feu clic a Fet

L’assistent d’aprenentatge només funciona amb dispositius MIDI. Per ara no es pot mapegar tecles de modificadors (majúscules) i controls. Utilitzeu Scripts MIDI en aquest cas.

11.2. Personalitza les dreceres de teclat

Les dreceres de teclat predefinides estan definides en fitxers de text que trobareu a la següent ubicació:

  • 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:

  1. Edit your system’s default mapping file directly, e.g. en_US.kbd.cfg.

  2. 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. Efectes addicionals utilitzant el mesclador extern

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

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.

Al Mixxx

  • Aneu a Preferències ‣ Maquinari de so ‣ Sortida

  • Des del primer desplegable al costat de Plat 1, el dispositiu Soundflower 16 i al següent Canals 1-2

  • Des del primer desplegable al costat de Plat 2, el dispositiu Soundflower 16 i al següent Canals 3-4

  • Feu clic al botó Accepta

Al AU Lab

  • Feu clic al botó + per a crear una nova configuració

  • Add 2 stereo inputs tracks in the Audio Input Tab

  • Afegiu dues sortides estèreo a Audio Output Tab

  • Feu clic a Acceptar

  • Canvieu el dispositiu d’entrada a Soundflower 16

  • Changethe audio output device for example to Built-in Output

  • Feu clic a Create document

  • In the Output 1 channel, select an effect from the drop-down menu, for example Apple > AUCompressor

L’efecte s’hauria de sentir si reproduïu una pista al Mixxx.

11.3.2. Efectes amb el JACK Rack a GNU/Linux

The Jack routing for external effects

Enrutament amb el JACK per a efectes externs a 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:


The Mixxx library is stored in the %USERPROFILE%\Local Settings\Application Data\Mixxx\ folder. To delete your library on Windows, delete the mixxxdb.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

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


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.
