TKFX is a new iPad app designed to offer DJs wireless touch control over various elements of Native Instruments' Traktor.
The app is focussed around a large X/Y pad, which can be assigned to control the parameters of any of Traktor's built-in effects, and then applied to any of the software's decks. According to its developers, the app is pre-mapped to be entirely 'plug-and-play' and offer intuitive integration with any Traktor set-up.
TKFX is a 'freemium' app, meaning that it's free to download in an entirely useable state, but requires in-app purchases to unlock the 'unlimited' modes of each of its features. Off-the-shelf, the app comes with a single bank, single effect unit, single deck, single effect parameter, three effects and one single effect function button.
