Reply to Traktor Advance Mapping, confusing....

I bought i-Mix Reload MKII. Downloaded the mappings from the website (DJ tech - Product Details). IT works great in traktor but one thing bothers me. I found a custom mapping which allows me to select effects in Deck 1 (3 FX) by using the FX's knobs when I hold "FX 2 SELECT", after I let go of that button the knobs allow me to apply those effects from 0 to 100% for the 3 FX.

I want to know how I can apply this to the stock tsi I get from the website. I was reading up about modifiers etc but I can't wrap my head around it, it's very confusing....


If you don't understand what I'm writing, I created a picture to help understand.



EDIT: Also wanna learn how to Hold a button, move a knob to apply it to something.
