The touch-strip lets you scrub through tracks, needle-drop, nudge the track in time and even scratch in a totally different way to how you might with a jog-wheel. Novation have come up with a great idea here and it's nice to see someone thinking hard about how we interact with the new-wave of DJ products. Other than that, the Twitch fills in all the other parts of a DJ controller/interface you might want. It's robust, the up-faders and cross-fader are all replaceable and the audio interface delivers high-quality audio as you would expect from a Novation device. The Twitch ships with Serato's Itch DJ software as standard (which is giving our friends at Traktor a pretty good run for their money these days) but, if you're already a Traktor head then an overlay and .tsi file is provided so, you can hook up with Native Instruments' industry standard instead. Another innovative winner from Novation!
