Xone:K2 and the Latching Layers System
The layers system of the Allen&Heath Xone:K2 allows you to easily create mappings with just one layer, or if you wish with different, multiple layers.
Mappings with several layers do not require Modifiers
For mappings with several layers you do not have to use the Traktor modifiers.
The MIDI messages sent by the controls of the K2 are different and unique, and
depend on the layer currently active. This means that the layer architecture is
controlled by the hardware of the Xone:K2 and that you do not need to implement the layers on the software side by using modifiers. This will allow even Traktor
beginners, who are not very familiar with the modifier concept to be able to create multiple layered mappings.
The Latching Layers
The latching layers system of the Xone:K2 allows you to define the blocks of the
controller that stay the same when you switch layers and that should act differently. The K2 provides different modes and this mode defines the behaviour of the
different blocks. The layers mode can be configured on the controller; no
software is needed.
As far as we know the following modes will be supported:
Mode 1 – No Layers/Virtual Layers
In Mode 1 the latching layers system is disabled, which means that the controller has one layer and that all controls always send the same MIDI message (left image).
However, the Layer button in the lower left of the controller always sends a MIDI message to the application. If none of the other modes suite your needs, you can create "virtual layers" and use the Layer button to set a modifier in Traktor and then create
the layer definition exactly as you need it.
The image on the right side for example shows how virtual layers can be defined.
In this example the left side of the controller always controls the same
functionality of Traktor and the right side of the controller has several
layers. As this kind of mapping requires the use of modifiers, it is probably more
suited to the advanced "Traktor mapper"..

Mode 2 – Lower Button Block
In Mode 2 only the 16 buttons below the faders change (i.e. send different MIDI
messages) when you switch between layers. The messages sent by all other controls
stay the same.
Mode 3 – Switches below potis and of push encoders
In Mode 3 the twelve buttons below the knobs/pots and the push action of the
four encoders send different MIDI messages when you change the layer. The
messages sent by all other controls
stay the same.
Mode 4 – All Buttons
Mode 4 is a combination of Mode 2 and Mode 3. In this mode the following controls send different MIDI messages when you switch between layers:
- the switches (i.e. the "pressing the encoder" action) in the push encoders
in the upper part of the controller,
- the twelve buttons below the knobs/potis
- the sixteen buttons in the lower part of the controller
The messages sent by all other controls stay the same.
Mode 5 – All Controls
In Mode 5 all controls send different MIDI messages on all three mapping layers.
