The Ctrl key on Windows & Linux is equivalent to the Command key on Mac OS X. The Alt key on Windows & Linux is equivalent to the Option key on Mac OS X. Application shortcuts are not customizable.


The Developer menu is available if Mixxx is started using the Command line options.

13.3. Command line options

Mixxx is designed to be as user-friendly as possible. As such, its command line options are only useful for development or debugging, as they make these tasks easier. Command line options are case-sensitive.

Nieuw in versie 2.0:

  • Show debug tooltips

  • Provide extra skins when developer mode is enabled.

  • Adds the debugger during skin parsing in --developer mode

  • Adds “Enable Base” and “Enable Experiment” option in --developer mode

  • Added --safeMode option.




Load the specified music file(s) at start-up. Each file you specify will be loaded into the next virtual deck. Supported file types: mp3, ogg, aiff, aif, wav, flac, and optional unprotected aac (m4a)

–resourcePath PATH

Top-level directory where Mixxx should look for its resource files such as MIDI mappings, overriding the default installation location.

–pluginPath PATH

Top-level directory where Mixxx should look for sound source plugins in addition to default locations.

–settingsPath PATH

Top-level directory where Mixxx should look for user settings files such as the library database and preferences configuration file.


Causes Mixxx to display/log all controller data it receives and script functions it loads.


Enables developer-mode. Includes extra log info, stats on performance, a Developer tools menu, extra developer skins, and provides useful information for skin writers in widget tooltips and logs .


Disables risky things at start up. This should help troubleshoot crashes at startup or if Mixxx won’t boot.

  • Automatically loads empty waveforms

  • Disables spinning vinyl widgets

  • Disables synchronization polling

  • Doesn’t open controllers by default

–locale LOCALE

Use a custom locale for loading translations (e.g ‘fr’)

-f, –fullScreen

Starts Mixxx in full-screen mode

-h, –help

Display this help message and exit

13.4. Developer tools

To start Mixxx in Developer mode from a custom resource directory with MIDI and HID logging enabled, type the following line into the terminal and hit return:

./mixxx --controllerDebug --developer --resourcePath res

13.4.1. Experiment modes for rapid development and testing

Nieuw in versie 2.0:

  • Adds a static Experiment class with a tri-state mode flag that indicates whether the experiment mode is OFF, BASE, or EXPERIMENT.

  • Adds Developer‣Stats:Experiment Bucket and Developer‣Stats:Base Bucket. Each one toggles between OFF and BASE/EXPERIMENT so you can choose exactly what time spans you would like to collect in your base and experiment buckets.

  • Updates StatsManager to segment collected stats into a base and experiment bucket. This allows you to quickly measure the difference a code change has on relevant counters / timers within the same execution of Mixxx.

This is useful for quickly enabling and disabling a code change without a re-compile/re-run cycle to get an anecdotal sense of how it “feels” as well as a quantified sense of how it differs in terms of stats Mixxx collects.

All stats collected via the usual Counter/Timer/ScopedTimer/etc. tools are segmented into a BASE STATS and EXPERIMENT STATS section printed to the log on exit.
