Richie Hawtin goes even further, and I believe he truly can be called an Pioneer of Music:

He uses the Traktor FX and Ableton FX on the AUX 2 of the Xone:92, where the AUX 1 is reserved for the Maschine. By routing the FX external, there's more headroom and it all sounds more natural to me, because by doing this, you can make the FX post-fader (because the FX goes straight to the master, and therefore you can just slam the faders down with a tail!) and second, within Traktor use of FX will make the incoming sound louder and can cause clipping within Traktor. With Hawtin's method, the FX comes in on the Xone:92 and as you might know, this mixer has more headroom than Traktor. So you can avoid clipping!
