Not fully thought through
The layering system works okay but a shift type button would have also been nice. The knobs, faders, and buttons are Allen and Heath quality and feel great. Complete RGB led backlit buttons would have been nice, the K2 only has 3 possible colors that are not changeable with midi talkback. I am using it as a midi mixer and for that it works great, could be spaced out more, but it is not promoted as a mixer so that is understandable.
