The actual behavior of CUE and Play/Pause buttons depends on Mixxx settings. See The Mixxx User Interface for more info.

FX

Pitch up/down buttons change pitch by one semitone.

Hint

Pads

The 8 pads in each deck have multiple functions, depending on the selected pad mode. Default pad mode is hotcues. Current mode is selected by pressing one of the buttons above the pads. The button for currently active pad mode is lit up (or blinking, when secondary pad mode is selected - secondary pad modes are: beatjump and sampler 2).

Pads support secondary (shift) actions in most pad modes. 4 bottom pads with “special” functions printed on them (STUTTER, etc.) act the same as the top 4 pads, i.e. don’t perform any special functions.

#	Name	Function
30	CUE	Change pad mode to hotcues. Pad press: set hotcue if not set. If set, go to hotcue position and start playback SHIFT + pad press: remove hotcue (if set) Pad lights indicate if a particular hotcue is set or not.
30	SHIFT + CUE	Change pad mode to beatjump. Pad press: beatjump forwards SHIFT + pad press: beatjump backwards If loop is active, loop is moved forwards/backwards instead. Default beatjump values are: 1/16, 1/8, 1/4, 1/2, 1, 2, value set in Mixxx GUI (4 by default), 8. Values can be adjusted, see the Adjustable values section.
31	AUTO LOOP	Change pad mode to auto-loop. Pad press: activate auto-loop SHIFT + pad press (hold): activate beatlooproll. When released, playback will resume where the track would have been if it had not entered the loop. Default auto-loop sizes are: 1/16, 1/8, 1/4, 1/2, 1, 2, 4, 8. Loop sizes can be adjusted, see the Adjustable values section.
32	FADER CUTS	Change pad mode to fader cuts This pad mode emulates rapid crossfader movements. Pad press (hold): activate a fader cut. The crossfader will rapidly move in one of the 8 available patterns. The crossfader will return to the position of hardware crossfader after the pad is released. Note: this function is controlled by the hardware or firmware
33	SAMPLE	Change pad mode to sampler 1 (samples 1-8) Pad press: play a sample SHIFT + pad press: stop sample playback
33	SHIFT + SAMPLE	Change pad mode to sampler 2 (samples 9-16)
34	Performance pads	Various functions, depending on selected pad mode
34	SHIFT + Performance pads	Various functions, depending on selected pad mode

Adjustable values

There are a few configurable values at the top of the script (Numark-Mixtrack-Pro-FX-scripts.js).

Variable	Default value	Description
`pitchRanges`	[0.08, 0.16, 1]	For adjusting the range of pitch fader. Pressing PITCH RANGE (SHIFT + PITCH BEND -) cycles through available values. Number of values in the array can be changed without further script modifications. Note that the default (first) pitch range must be also selected independently in Mixxx settings (Settings -> Preferences -> Decks -> Slider range).
`waveformsSynced`	true	This variable should reflect the corresponding Mixxx option (Settings -> Preferences -> Waveforms -> Synchronize zoom level across all waveforms). This affects waveform summary zooming.
`jogScratchSensitivity`	1024	Scratching sensitivity
`jogScratchAlpha`	1	For controlling the alpha-beta filter used in scratching
`jogScratchBeta`	1/32	For controlling the alpha-beta filter used in scratching
`jogPitchSensitivity`	10	Jogwheel pitch bend sensitivity
`jogSeekSensitivity`	10000	Jogwheel seek sensitivity
`enableBlink`	true	Enable blinking of pad mode buttons when in secondary mode (beatjump or sampler 2)
`blinkDelay`	700	Blinking frequency of pad mode buttons when in secondary mode (in ms)
`autoLoopSizes`	[“0.0625”, “0.125”, “0.25”, “0.5”, “1”, “2”, “4”, “8”]	Loop sizes for the auto-loop pad mode, each value corresponds to one of the pads.
`beatJumpValues`	[“0.0625_”, “0.125_”, “0.25_”, “0.5_”, “1_”, “2_”, “”, “8_”]	Beatjump values for the beatjump pad mode, each value corresponds to one of the pads. The empty value (“”) means the value set in Mixxx (4 by default). Underscores (_) are needed because of that control, which has one underscore in the name, as opposed to beatjump controls with predetermined values which have two underscores.

Hint

See here for more info about constants used in scratching.

Notes

Pressing either SHIFT button will cause both decks to shift (e.g. when pressing SHIFT on deck 1 and then some control on deck 2, the secondary function will be executed). This approach was chosen to be consistent with the behavior of hardware - i.e. pressing either SHIFT changes midi codes of some controls on both decks.
SHIFT + TAP does not trigger BPM rescan, as there is no Mixxx control for this action.
