This thing is a beast. It has great sounds that can add miles to your performance. We have even used it for main leads and baselines or FX transitions in our own songs too. Its like adding an element of freestyle jazz to your live DJ routines, you never really know what fun sounds you will add to a mix. Also extremely easy to customize with your own sounds, SD cards are literally the most important piece of gear that you can have, and the Kaossilator dominates!
Not terribly accurate, but great for patterns using gates, fun to integrate into your live rig. Although, you get bored of the onboard beats and sounds after a few years.....
i use this machine to loop my microkorg XL synth. it works super well and can create a fully flushed out song in real time - live! i just wish you could put more than a 2gb sd card in there
