Problems mapping multiple effects on Numark Mixtrack Pro

Hello all,

I recently joined this community and was made familiar with a mapping tutorial for Traktor. So far everything is fine and I'm learning quite fast. However I stumbled upon a problem. I downloaded a custom TSI file for my Numark Mixtrack Pro, and I found something I want to change and eventually reproduce in my own mapping.

In this custom TSI file there is a group of settings mapped to my cue gain knob. When I turn my cue gain knob, one effect bank with three effects (icy verb, peakfilter and reverb) is triggered. I believe this is called chained effects or grouped effects(?). Anyway, this allows me to create a sort of sweep/buildup effect. By turning the cue gain knob the strength of all three effects increases simultaneously.

Now I've been trying to change the effects that are triggered, but as I change the effects in the mapping options from lets say peak filter to gater, the knob only turns on the three effects, but the value/strength bar of the effects stays stuck at zero. The new effects are correctly displayed but I can't increase their strength with the cue gain knob.

I hope you are able to follow me, if not I will post some screenshots!

Thanks in advance,

Zarael
