NI continues to impress me with their line of products and the kontrol x1 mk2 is no exception. really needed something portable for quick gigs at house parties.even though its light, its well built and is extremely stable without any glitches. Generally speaking, the original X1 was designed as a side-caddy to whatever isperforming the actual mixing duties (volume, gain, EQ, filter). highly recommend it for most users who are just starting out as well. I got it with Traktor pro completeduring a promotional offer. sweet deal!
