I edited the "Twister Instant Mixer FX" mapping for the use of 2 decks and added Ian's transition FX chains to it. In the middle of the Twister you have the mixer FX for deck a+b and the left and right rows of knobs are controlling the FX chains similar to the Kontrol X1mk2. With the left and right top knob, you can select the FX chain and also reset the dry/wet parameter. The FX chain on the left is using another filter then Ian does. The FX chains are set up for FX-Unit 2 and 4 in Traktor.
