These devices don’t come with any out-of-the-box mapping (other than the one for the DB4) or labels on the individual interface elements. The effort required to implement the mappings is well compensated by the potential to develop very flexible and highly personalized hardware-to-software relationships. Allen & Heath Xone K2 is an extremely compact, powerful and versatile MIDI controllers with a built in 4 channels audio interface. I’ve been using a variable number of these devices for mappping the control and visual feedback in real-time audio or audio/video applications within Max/MSP, Ableton Live, Max for Live, to control the looper of the Xone DB4, and also for djing with Native Instrument Traktor Scratch Pro.
