If the Xone is not listed, either the computer doesn't recognise the device or the driver is not installed correctly.

X-Link is a proprietary connection that allows A&H devices to speak to and power each other. With USB ports dropping like flies on new computers (okay, mainly Macs), anything that allows a device to daisy chain is a good thing. Better still is the fact that power for the device will be drawn from the host if it’s plugged into the mains, so if you absolutely must use a USB hub for whatever reason, a Xone mixer/K2 combo won’t be swallowing precious power. I would strongly recommend this controller to beginner/medium level Digital DJ’s that like small & efficient setups, but also need power in terms of sound and functionality and don’t mind to spend a couple days mapping and trying stuff out.Nirmal Purja (18 January 2021).

With a day or so, I am confident I could get everything else mapped and have a great little custom controller for that software, using at least one of the layers for effects (for instance). Most ascents are made during July and August, typically the warmest times of the year.

The Allen & Heath Xone:K2 is a modular DJ and audio production controller with four faders, 12 pots, 6 rotary controllers, 24 buttons and the ability to output two stereo channels of audio. It also has two Ethernet ports that let you attach your Xone:K2 to another Xone:K2 or to a compatible Allen & Heath mixer so they can share data and power, and a layer button that lets you switch between three layers of controls. Their Xone:K2 MIDI controller features a 4-channel soundcard for use with any DJ software or DAW , 52 hardware controls providing up to 171 MIDI commands across 3 layers – plus the ability to link multiple units using X:LINK, saving USB ports on your computer.

Allen & Heath provides clear, colour charts in the manual showing the exact Midi note implementations for all controls, so for instance when you want the aforementioned lights to come on and off to indicate the states of buttons, it’s not difficult to look up what to tell your software to send to the unit. By the way, it’s simple to change the Midi channel too with a two-step setup routine. It hasn’t failed me once. Great sound quality, great build, and once you get around the mappings, great fun to play around with. Messner, R.; Gogna, A.; Salked, A. (1982). K2 Mountain of Mountains (in German).
