Need to get this right once and for all

I have Macbook Pro, Traktor Scratch Pro II with 2 Kontrol X1's, Audio 10, Ableton Live 8, Allen & Heath Xone 92, and Maschine.

Now after watching DJTT's How I Play video with Chris Liebing, it got me on doing the same thing, tho i discussed it on here and realised that i couldnt achieve the same thing as I only had an audio 10, and needed a bigger souncard like Chris' (RME fireface UCx i believe), plus he has 2 laptops, one running traktor and the other running ableton with maschine as a plugin.

So, my set up goes like this:

4 traktor decks, on channel 1-4 on the Xone 92.
Maschine opened as a plugin in Ableton Live 8, with the sound coming out from my xone 92 MIC/RTN 1. I have this routed by RCA from the MAIN OUT 1/2 of the audio 10, and into the Return 1 of the xone 92.

All good, i can apply ableton fx/plugins over my maschine stuff, cool.

now i have RCA from Audio 10 IN 3/4 (the first input at the back) and this is going to the AUX 1 of the Xone 92. (im not sure what this is even doing, as when i unplug this connection, everything still plays, and i can still apply FX over maschine from ableton. Someone who helped me with setting it up told me to do that.

Anyhow, now that im able to apply ableton fx over maschine, and have that out my xone 92, plus have all 4 channels/traktor decks, im happy. But still wanting to achieve something that was the main focus, applying ableton over Traktor decks......

Now i know i cant apply ableton fx over all 4 traktor decks as apparently i need more outputs on my soundcard, i only have 4 INs from the track decks, and 1 IN from MAIN IN. The strange thing is, when i create another audio track in ableton and set the 'audio from' to the input that i routed the Aux 1 to, so, Input 3/4 of my audio10, i dropped a delay onto the 'insert effects here' section, and when i turn the AUX 1 knob which is above the xone 92 channel, so channel 1, i could hear the delay over my traktor track.... tho i had to be careful because if i turned it up too much, it sounded like it was going to blow up! And also, i had to press 'monitor' to IN, as thats the only way it worked, maschine is just on 'auto'

It applied the FX on everything single channel... so 1-4/deck A-D, i could use the Aux 1 knobs above each channel to send it into the delay, now this didnt seem right as i need 4 extra outputs on a soundcard to achieve this, so how am i doing it?

The weird thing is, i changed the delay to a reverb, and when turning the Aux 1 knob for each channel, it reverbed the track, but there was also a delay, as if the track was doubling up, so this makes me believe that theres something bad going on, where my audio is somewhere looping up/doubling on each channel, because i should be able to turn the aux 1 knob of each channel up fully so i get the full 100% of the FX, but its not happening like that, its really loud and sounds like its about to blow.

So does anyone know what is going on here? I've added some screenshots of how things in ableton are. Hope someone can help.

And maybe its that i simply cant safely apply traktor decks with FX from ableton as i dont have the spare outs on my soundcard, its just strange that can actually do it, it just doesnt feel safe, i might accidentally pull the aux 1 knob to high and blow the world up.
