Hint
The Ctrl key on Windows & Linux is equivalent to the Command key on macOS. The Alt key on Windows & Linux is equivalent to the Option key on macOS. Application shortcuts are not customizable.
Note
The Developer menu is available if Mixxx is started using the 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.
--debugAssertBreak option
--logLevel option
--logFlushLevel option
--controllerDebug option also prints outgoing MIDI messages
Option |
Description |
|---|---|
[FILE] |
Load the specified music file(s) at start-up. Each file you specify will be loaded into the next virtual deck. For a list of supported file types, go to Changing music directories |
–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. |
–controllerDebug |
Causes Mixxx to display/log all controller data it sends and receives, and script functions it loads. |
–developer |
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 . |
–safeMode |
Disables risky things at start up. This should help troubleshoot crashes at startup or if Mixxx won’t boot.
|
–locale LOCALE |
Use a custom locale for loading translations
(e.g |
-f, –fullScreen |
Starts Mixxx in full-screen mode |
–logLevel LEVEL |
Sets the verbosity of command line logging
|
–logFlushLevel LEVEL |
Sets the the logging level at which the log buffer
is flushed to |
–debugAssertBreak |
Breaks (SIGINT) Mixxx, if a DEBUG_ASSERT evaluates
to false. Under a debugger you can continue
afterwards. This will also avoid to switch the
MIXXX_DEBUG_ASSERTIONS_FATAL flag which leads to
a time consuming full rebuild. Now the
MIXXX_DEBUG_ASSERTIONS_FATAL is only respected if
|
-h, –help |
Display this help message and exit |
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
Adds a static Experiment class with a tri-state mode flag that indicates whether the experiment mode is OFF, BASE, or EXPERIMENT.
Adds and . 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.
