Allen & Heath Xone:K2/K1

www.allen-heath.com_media_xonek2_front_main-463x1024.jpg

The Allen & Heath Xone:K2 is a flexible controller that is mapped to control Mixxx's decks, effects, or both. It has an integrated 4 channel audio interface with 2 RCA jacks and an 1/8“ stereo headphone jack. The Xone K1 is the same as the Xone K2 but without the built in audio interface and does not come with the EVA travel case that the K2 comes with.

Audio setup

Configure channels 1-2 for Mixxx's Headphones output and channels 3-4 for the Master output (this is the opposite of most DJ controllers with an integrated audio interface).

There are no hardware controls for the volume; they are always at full volume. You can adjust the volume of the master and headphone outputs by adjusting the gain controls for those outputs in Mixxx with the controller mapping.

Mixxx 2.1 mapping

Setup

This mapping can used with one or multiple Xone K2s/K1s. Multiple Xone K2s/K1s can be connected to each other via X-Link with one of them connected to the computer via USB. Alternatively, when using 2 K2s/K1s, they can both be connected with their own USB cable and this same mapping can be loaded for each.

The layout of the mapping depends on the configured MIDI channel of the controller. Change the MIDI channel of the controller by pressing the bottom right encoder (labeled “Power On Setup/Scroll/Set”) while plugging in the controller. Scroll with the encoder to select a MIDI channel. The letter in parentheses corresponds to the last lit button when selecting the channel:

  • Channel 15 (O, default out of the box): two decks + two effect units with decks in the middle
  • Channel 14 (N): two decks + two effect units with effect units in the middle
  • Channel 13 (M): two decks + two effect units with decks on left
  • Channel 12 (L): two decks + two effect units with decks on right
  • Channel 11 (K): four decks ordered 3 1 2 4
  • Channel 10 (J): four decks ordered 1 2 3 4
  • Channel 9 (I): four effect units ordered 3 1 2 4
  • Channel 8 (H): four effect units ordered 1 2 3 4

If you are using K2s, they must have Latching Layers turned off, which is the default (the K1 does not have Latching Layers). Refer to the Xone K2/K1 product manual from Allen & Heath for details.

Global controls

These are available on any configuration with decks, but not the 4 effect unit layout.

  • Bottom left encoder:
    • adjust tempo of all decks with sync enabled
    • press and turn: PFL/master mix in headphones
    • shift: headphone gain
    • press with shift: toggle split cue mode
  • Bottom right encoder
    • scroll through tracks in library
    • press and release: load selected track into first stopped deck
    • press and hold: load selected track into a deck by pressing the play button of the deck
    • shift: master gain

Decks

The bottom right button is the shift button. The bottom left button toggles the bottom button grid between a loop layer (amber) and a hotcue layer (red). Holding shift then holding the bottom left layer button at the same time activates supershift mode.

  • Top encoder:
    • jog
    • shift: key
    • supershift: gain
  • Top encoder press:
    • sync
    • shift: reset key
    • supershift: reset gain
  • Knobs: high/mid/low equalizer knobs
  • Top button 1:
    • headphones/PFL
    • shift: reset tempo
    • supershift: set beatgrid to current position
  • Top button 2:
    • cue
    • shift: go to beginning of track and stop
    • supershift: keylock
  • Top button 3:
    • play
    • shift: reverse
    • supershift: quantize
  • Fader: volume
  • Bottom buttons (loop layer):
    • Bottom button 1 (red):
      • reloop/disable loop
      • shift: jump to to beginning of loop, stop playback, and activate loop
      • supershift: set loop in point. Hold to move loop in point with play position.
    • Bottom button 2 (green):
      • activate loop of selected size
      • shift: activate rolling loop of selected size
      • supershift: set loop out point. Hold to move loop out point with play position.
    • Bottom button 3 (amber):
      • beatjump forward by selected size if no loop is enabled. If loop is enabled, move the loop forward by the beatjump size.
      • shift: double loop size
      • supershift: double beatjump size
    • Bottom button 4 (amber):
      • beatjump backward by selected size if no loop is enabled. If loop is enabled, move the loop backward by the beatjump size.
      • shift: halve loop size
      • supershift: halve beatjump size
  • Bottom buttons (hotcue layer, red):
    • activate hotcues 1-4 or set the hotcue if the is not one set yet
    • shift: delete hotcues 1-4

Effects

The top part of the column uses the Standard Effects Mapping. Pressing the top encoder acts as the effect focus button. When no effect is focused, the buttons are red. When holding the top encoder to choose an effect to focus, the buttons are green. When an effect is focused, the buttons are amber.

The fader acts as the dry/wet knob.

The bottom buttons assign the effect unit to different input channels and light up red. On the two deck layouts, from top to bottom, they assign the effect unit to deck 1, deck 2, master mix, and headphones. On the four effect unit layouts, they assign the effect unit to decks 1-4 going down the column. You can look down a column to see which decks an effect unit is assigned. You can look across a row to see which effect units are assigned to a deck. When shift is pressed, the bottom two buttons switch to controlling the routing buttons for the master and headphones channels and light up amber.

The bottom encoders are not mapped in the 4 effect unit layout.

Effect unit focusing

In addition to focusing one effect in a unit at a time with the Standard Effects Mapping, the Xone K2/K1 has another mode for focusing a whole effect unit. This allows for controlling the parameters of all 3 effects in the unit at a time. This mode is only available on the 4 effect unit layouts. To access it, press the Layer button in the bottom left. Press one of the top encoders to choose which effect unit to focus.

In this mode, each horizontal row of knobs and buttons controls one effect. The knobs control the parameters of the effects. Turning any of the knobs with shift loads different effects. The button in the leftmost column controls the enable button of the effect and turns amber when it is on. The rest of the buttons control the button parameters of the effect and turn green when active (not all effects have button parameters). The faders still control the dry/wet knobs and the bottom button grid still controls the routing buttons.

To get back to controlling all 4 effect units, press the Layer button again. The next time Layer is pressed, the effect unit that was focused before will be remembered (but it will not be remembered after restarting Mixxx).

Troubleshooting

If your K2 switches between 3 layers (amber, red, and green) instead of 2 (amber and red only) and supershift does not work, make sure Latching Layers is turned off. Refer to the Xone K2 product manual from Allen & Heath for details.

Mixxx 2.0 mapping

For the mapping to work correctly, the device must be set to operate on MIDI channel 16 and Latching Layers must be set to “Switch Matrix” (2nd state). For information on how to do that read the manual from Allen & Heath. Latching Layers is not available on the Xone K1, so this mapping is not compatible with the Xone K1.

The behavior of the grid buttons depends on which layer is active, which is changed by pressing the Layer button in the bottom left. The color of the text background indicates what the button does in that layer, e.g. the buttons of the last row activate hotcue 4 when the green layout is selected, but act as the play button when the red layer is selected.

Text in blue describes secondary functions accessible when the shift button is held down.

Xone K2 Mapping

Known issues

There are a few known issues with the Xone K2/K1 firmware. First, there is no way for Mixxx to ask the controller about the positions of all the knobs and faders when Mixxx starts, so they are out of sync with the state of Mixxx until they are first moved. Also, when the USB connection is interrupted and the controller stays powered on, such as leaving the controller plugged into a powered USB hub and disconnecting the hub from the computer, the controller will not send MIDI input until it is powered down (unplugged) and plugged back in. If you would like these issues to be fixed, please let Allen & Heath Support know.
