This mapping was essentially created in order to practice Filter EQuing as the Xone DB2 parametric EQs offers the possibility.
Instead of the traditionnal High/Mid/Low, you have a High Pass/Resonance/Low pass filter for each decks.
It has to be said this mapping is not suit for all genres (especially the one that cuts a lot...), but is something you should try if you mix techno or deep stuff...
The mapping also offers from one to three macro fx, fully assignable on the different decks.
To make this concept mapping work, you MUST NOT click Play/pause with the mouse (it'll ruin the modifiers... But I mapped a reset if you do it so...) and the knobs needs to be put on the right position when you have fade out the tracks (or it'll ruin the MacroFX selection...)

A video and a demo mix are coming soon...
