Numark N4

Numark N4

This mapping features full 4-deck support and seamless integration of external devices.

This mapping has some unusual features like per Deck shift buttons and multiple pages of hotcues.

This overlay can be downloaded in a ready to print format for DIN and printers.

Definable Settings

Some settings in the script can be changed by editing them at the top of the script. You can find the Javascript file by opening the pressing the "Open User Preset Folder" Button in Preferences>Controllers and search for "Numark-N4-4channel-scripts.js". Configurable options are:

searchAmplification

Defines the speedup-factor used when using the searchbutton and scrolling.
type: number
range: ]0;+∞[
=== warnAfterTime === Time in seconds before the end of the track in which the controller should warn you.
type: number
range: [0;+∞]
=== blinkInterval === Timeinterval for the triangular Leds in ms
type: number
range: [20;+∞[
=== encoderResolution === Percent how much the value changes with each encoder tick
type: number
range: ]0;1]
=== resetHotCuePageOnTrackLoad === The Hotcuepage should be reset to 1 when a new Track is loaded into the Deck
type: boolean
range: true or false
=== cueReverseRoll === If [SHIFT]+[CUE] should trigger a reverse_roll
type: boolean
range: true or false
=== rateRanges === An array of rateRanges in percent
type: array
range: ]0;3]

Deck

The Deck consists of the jogwheel, play, cue, the topContainer (which hold the eight square buttons and the four encoders), pitchslider, pitchrange, search, keylock, tap, sync and pitchbend ±.

Special Features

The mapping features some peculiar features which might not be discoverable by standard trial-and-error.

Shift

A shift button is bound to its Deck, which means that you can't use the shift button of Deck1 to access a shifted function on any of the other three Decks. Moreover the shiftbuttons can also work as toggle switches instead of pushbuttons (enabled via components.js Button.type.powerWindow). This means that if the shiftbutton is pressed for a longer period than 275ms it will bounce back to its original state (like a regular shift-/pushbutton). If the Button was pressed for a shorter period than 275ms, the button will remain in that state until it is pressed again (like a toggling button).

Hotcues

The four lower buttons of the topContainer are hotcues. They can be changed by using the corresponding Encoder [HOTCUE PAGE]. The current assignment will then be shown for one second in the upper row. Currently up to 4 Pages are supported (with 4 hotcues each). A demo of how this looks can be seen on JsFiddle (not done yet) (the slider represents the Encoder).

Controls

Most of these controls behave as expected but they are listed in detail for the sake of completeness anyways.

Play

Default: Starts regular Play.
Shifted: Plays Track in reverse.

Cue

Default: Standard Cue.
Shifted: reverse roll if shift is enabled (plays in reverse end enables slip) otherwise standard cue.

Pitchbend ±

Default: Change rate temporarily.
Shifted: Change rate temporarily small.

Sync

Default: Momentary BPM Sync
* Short Press: Momentary BPM & Phase Sync

• Long Press: Toggle Master Sync (Sync Lock)

Shifted: Toggles magnet (quantize)

Tap

Default: Tap the desired BPM of the Channel
Shifted: ^^
Note: This functionality is broken until #1811 gets merged

Search/Scratch

Default: Enable Scratching (otherwise it just works just like moving the Jog without the platter)
Shifted: Speeds up platter movement for searching within the track

Keylock

Default: Toggles track keylock
Shifted: Syncs Key

Pitch Range

Default: Cycles Through pitchranges
Shifted: ^^

Pitch/Bpm slider

Default: Normal Pitchslider (Down plays faster; can be changed in the global mixxx preferences)
Shifted: ^^

TopContainer

The TopContainer holds four assignable Hotcue buttons, four loop buttons, which can enable FX via Shift, and four Encoderknobs.

Hotcues

Default: set/active Hotcue_X
Shift: clear Hotcue_X
visit #special_features for more info on how these work

Loop In

Default: Presses the Loop In button like in the UI
Shifted: Toggles EffectRack1

Loop Out

Default: Presses the Loop Out button like in the UI
Shifted: Toggles EffectRack2

Loop Here

Default: Creates a loop at the current position of current Loop Size.
Shifted: Toggles Slip

Reloop

Default: De-/Re-activates the last loop
Shifted: Jumps to start of last loop and stops playback there

FX1 Knob

Default: Controls the Super Knob on EffectRack1.
Shifted: Controls the Mix Knob on EffectRack1.

FX2 Knob

Default: Controls the Super Knob on EffectRack2.
Shifted: Controls the Mix Knob on EffectRack2.

Hotcue Page

Default: visit #special_features for more info on what this encoder does
Shifted: Double/Halve current Loop Size

Beat Jump

Default: Jump in the direction turned
Shifted: Double/Halve current Beat Jump Size

Mixer

The Mixer features four channels with identical functionality and controls for the library and other miscellaneous features.

Channel

A channel consists of a volume fader, a gain knob, knobs for low,mid,high EQ a Loadbutton and a pflButton. These are internally still part of the Deck which is why the shiftbutton of Deck 1 won't work with the Loadbutton or gainknob of Deck2/3/4.

Volume

Default: Channel Volume

CUE

Default: Channel Pre-Fader-Listening
these work as usual on the N4: Clicking another one deselect all other.
Press multiple at the same Time to PFL multiple Channels

BASS

Default: EQ Low

MID

Default: EQ Mid

TREBLE

Default: EQ High

GAIN

Default: Gain
Shifted: QuickEffect1 (Usually Filter)
=== LOAD === Default: Load Track into Deck
Shifted: Eject Track from Deck
==== Library ==== The Library is managed via the Library Encoder. Any shiftbutton can be used to access shift functionanly

Turn

Default: Move Library Cursor Vertically
Shifted: Move Focus between panes
sometimes the focus is stuck somewhere (eg when using the searchbox) and is only recoverable with user intervention via a pointing device.
=== Button === Default: Open/Close Folder / Load Item into first available Deck (Context-dependent)
Shift: Maximize Library
==== Miscellaneous ====

Crossfader

The Crossfader and its assignment buttons are integrated seamlessly with Mixxx.

Line/PC Input Source

Function as expected: Mutes the corresponding Deck in Mixxx if set to Line.

Crossfader Contour

Normal: Uses the crossfader parameters that were present when the mapping was loaded Scratch: Uses Scratch typical parameters for hard cuts

Cue-Master Mix

Doesn't manipulate the mixxx controls. Make sure the head gain is not zero and the mix is set to 100% PFL

Cue Volume

make sure its high enough within mixxx

booth/gain volume

expected behavior but doesn't manipulate any mixxx controls.

Troubleshooting

The only Mapping for the N4 I have works completely different

This is probably due to your Mixxx version not being up-to-date or this mapping not being merged yet. You can download the mapping directly on GitHub.
