11. Opciones Avanzadas

11.1. Mapeo de Mixx para controladoras MIDI/HID

With several dozens of DJ controllers supported out-of-the-box, Mixxx gives you comprehensive hardware control for your DJ mixes, see Using MIDI/HID Controllers.

Support for additional devices can be added to Mixxx by creating a new preset file. This file tells Mixxx how to translate, or map, MIDI/HID messages from a controller into commands that Mixxx understands.

You can download and share custom controller presets in the Mixxx User customizations forums.

11.1.1. Asistente para la configuración de la controladora

Asistente para el aprendizaje de la controladora - Mapeo de una acción.

Asistente para el aprendizaje de la controladora - Mapeo de una acción.

By far, the easiest way to create a new MIDI preset is by using the Controller Wizard.

  1. Conecte su controladora(s) al ordenador

  2. Active Mixxx

  3. Vaya a:menuselection:Preferences–>controladora

  4. Seleccione su controladora de la lista de dispositivos disponibles izquierda y el panel de la derecha cambiará.

  5. Active el :guilabel:”enabled’checkbox

  6. Haga clic en :guilabel:”Learning Wizard” para abrir el menú de selección.

  7. Haga clic en cualquier opción de Mixxx :term:”GUI”

  8. Por otra parte, haga clic en el :guilabel:”Elija Control” botón y elija una opción del menú de selección.

  9. Haga clic en configurar y luego utilice el control seleccionado o aprete un botón en su controladora para mapearlo. También se puede mover un control sin apretar el :guilabel:”learn” botón si está configurando muchas secciones.

  10. Si está configurando una acción, aprételo únicamente una vez. Si está configurando una perilla o un fader muévalo en todo su rango o trayectoria.

  11. After Mixxx detects the control, you may click Learn Another or you can click on another button in the Mixxx GUI to learn another control.

  12. Cuando termine el mapeo de controles, haga clic en :guilabel:”Proceso Terminado”

También existen opciones avanzadas en el Asistente que quizá necesitará utilizar:

  • Soft Takeover: Use this option for knobs or sliders to avoid sudden jumps in when the knob in the GUI doesn’t match the physical knob. If you select this option, you won’t be able to perform super-fast motions as easily. (Recommended off)

  • Invert: Use this option for controls that you want to work backwards from how they were detected.

  • Modo de Activación: Utilice esta opción en controladoras que tengan controles que actúen como interruptores y emiten un valor la primera vez que pulsa, y uno diferente en la segunda pulsación. (Piense en un hardware o flip-flop de conmutación, o en un botón que se ilumina en la primera pulsación y se apaga en la segunda pulsación).

  • Plato / Perilla de selección: Use esta opción para perillas que no tienen un inicio o un fin, pero que giran de contínuo.

The Controller wizard saves the new preset to the following file paths:

  • Linux: /home/<username>/.mixxx/controllers

  • Mac OS X: /Users/<username>/Library/ApplicationSupport/Mixxx/controllers

  • Windows: %LOCALAPPDATA%\Mixxx\controllers

You can then modify the XML file it creates (or any of the ones that ship with Mixxx) if you’d like to fine-tune it or add more presets. For more information, go to http://mixxx.org/wiki/doku.php/midi_controller_mapping_file_format.

El sistema de configuración de controladoras sólo funciona con sistemas MIDI. No se pueden mapear los botones de funciones (shift) y rotación de platos. En lugar de intentar esto use MIDI Scripting

11.1.2. Configuración de la Secuencia de Comandos MIDI.

Para poder se compatible con características avanzadas de muchas controladoras MIDI/HID, Mixxx ofrece lo que se conoce como Encriptación MIDI.

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 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 and http://mixxx.org/wiki/doku.php/hid_mapping_format.

11.2. Cómo realizar un mapeo de teclado personalizado.

El <appendix-keyboard> mapeo por defecto del teclado se encuentra definido en un archivo de texto que se puede encontrar en la siguiente dirección:

  • 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 system’s 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.

It is not recommended that you modify the system-wide keyboard mapping file because all your changes may be lost if you uninstall or upgrade Mixxx. Instead, copy the default mapping file to the following location:

  • Linux: ~/.mixxx/Custom.kbd.cfg

  • Mac OS X: ~/Library/ApplicationSupport/Mixxx/Custom.kbd.cfg

  • Windows: %LOCALAPPDATA%\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 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. Efectos Adicionales mediante Mezclador externo

Mixxx comes with a set of native effects. Additionally, using the external mixer mode you can route each deck directly to 3rd party effect hosts.

The following examples are only intended to encourage experimentation, they are not 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 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.

En Mixxx

  • Vaya a Configuración ‣ Hardware de Sonido‣ Output

  • Seleccione para Deck 1 the Soundflower 16 hardware con Canales 1-2

  • Seleccione para Deck 2 the Soundflower 16 hardware con Canales 3-4

  • Haga clic en el botón Apply

En AU Lab

  • Haga clic en el botón + para crear una nueva configuración.

  • Add 2 stereo input tracks in the Audio Input Tab

  • Añada 2 canciones entrantes en el apartado de Audio Input.

  • Haga clic en OK

  • Cambie la entrada de audio a Soundflower 16

  • Cambie la salida de audio, por ejemplo a Built-in Output

  • Haga clic en Crear documento

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

El efecto debería funcionar si usted hace sonar una canción en Mixxx.

11.3.2. Efectos via JACK en GNU/Linux

The Jack routing for external effects

El enrutamiento para efectos externos en GNU/Linux

Use Jack to route each deck directly through JACK Rack effect racks, or for more control you can use Ardour (or another 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 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
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

Advertencia

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.
