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¶
Pendent
Add intro and proofread
Connecteu la(les) controladora(es) a l’ordinador
Inicieu el Mixxx
Aneu a
Seleccioneu el dispositiu de la llista de dispositius disponibles de l’esquerra, i canviarà la informació al panell dret
Marqueu la opció Activat
Feu clic a Assistent d’aprenentatge per a obrir la finestra de selecció
Feu clic a qualsevol control de la interfície
També podeu fer clic al botó Trieu el control i trieu-ne un de la llista
Move a control on your controller to map it. Repeat this as many times as you wish.
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:
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. 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 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.

11.3.2. Efectes amb el JACK Rack a GNU/Linux¶

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:
- 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
Avís
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.
