It's another of those reviews that should've been posted a dogs age ago, but better late than never I say. Native Instruments' Traktor Kontrol S4 was the controller that had been rumoured since the dawn of MIDI controllers, but never quite made it to market. But when it finally did, It embraced the current crop of must have featured and executed them in a perfect symbiosis of hardware and software. Or was it? Andrew Unsworth had a look (some time ago I might add), wrote words and I took pictures (considerably later than I should).
