Mixxx Controls

What is a control?

Nearly every knob, button, or fader you see in Mixxx's interface is controllable via Mixxx's "control" system. The control system allows skins, MIDI controllers, and HID controllers to control Mixxx via a single interface.

A control is identified by a "group" (which is used for grouping associated controls) and a "key" (the name of the individual control).

For example, the volume fader for Deck 1 is identified by the group [Channel1] and key volume. Similarly, the volume fader for Sampler 1 is identified by the group [Sampler1] and key volume.

The group is used to collect all the controls that affect one component of Mixxx into one collection. Some groups have a high overlap of controls in common (e.g. samplers, decks, and the preview deck all share the same control keys).

In addition to controlling Mixxx, the control system can be used to inspect Mixxx's state. For example, the sample rate of the track loaded in Deck 1 can be accessed via the [Channel1], track_samplerate control. You can read the [Channel3], play control to determine whether Deck 3 is playing.

The following tables list the keys associated with each group.

Tip: Discovering Controls used in Skins

You can view the control connected to any part of a skin by running Mixxx with the --developer command line option and hovering your mouse cursor over part of the skin. If no tooltip appears, enable tooltips for the Library and Skin in Options > Preferences > Interface.

Tip: Changing any control from the GUI in Developer Mode

When running Mixxx in Developer Mode (with the --developer command line option), you can view and manually set the state of any control in Mixxx by going to Developer > Developer Tools.

Naming Conventions

The keys of existing controls use different naming conventions, namely

• PascalCase: VuMeter, MoveUp, ...
• camelCase: headSplit, duckStrength, ...
• snake_case: beatjump_forward, cue_indicator

Newly added controls should use the snake_case naming convention[1].

List of Controls

The default range is 0.0 to 1.0, unless otherwise noted. Binary means that it is either 'ON' (non-zero) or 'OFF' (zero).

Please keep the controls in alphabetical order within each group.

[Various]

The following extensions add some features to ControlPotMeter controls (volume, crossfader, ...). Use in conjunction with [Channel*N*], [Sampler*N*], [Master] ... groups. Please note, this doesn't work in JavaScript files, so you can not do, for example, engine.setValue('MyController', 'keylock_toggle').

[Master]

• J ranges from 1 to [Master],num_samplers, inclusive.

Linking Values

Effect parameters can be linked to the effect's metaknob. This linkage can be user-controlled by changing the link_type and the link_inverse control of the parameter. The default link type is loaded from the effect parameter's manifest's linkHint property.

Link Type	Integer Value	Intepretation
None	0	Not controlled by the metaknob
Linked	1	Controlled by the metaknob as it is
Linked Left	2	Controlled by the left side of the metaknob
Linked Right	3	Controlled by the right side of the metaknob

Link Inverse	Integer Value	Intepretation
Normal	0	Linked in equal relation
Inverse	1	Linked in an inverse relation.

EQs and filters

Starting in Mixxx 2.0, the equalizers and filter controls have been moved to special effects units. The EQs are controlled by [EqualizerRack1_[ChannelN]_Effect1] and the filter knob is controlled by [QuickEffectRack1_[ChannelN]],super1 and [QuickEffectRack1_[ChannelN]_Effect1],enabled. Users can choose between several options for the effects loaded in these racks in the Equalizers section of the Preferences window.
