This mapping contain all of necessary commands that I've used to use for lots of my custom mappings where any of Traktor decks becomes "armed" with four FX Units. Pressing any of deck buttons INSTANTLY engage all four FX Units to that deck but also disengages all of other decks if any of them were previously engaged. There is also a second use case where you can "arm" multiple decks if you hold any deck button while pressing and selecting your other decks. This mapping will work right away with a MidiFighter Spectra but you can easily re-map and integrate it to any other controller of your choice since each command is addressed to the specific deck button - just search the comments!

Download and un-zip the file and you should see a .tsi file inside.

Important Note: Each deck button is also activating the LED output. If you're using non multicolor button controllers ensure to change max value for FX Unit 4 On to 127. Repeat this step for all of four output commands.
