X:one Return Track Recording (Ableton)

Hey Folks - Riddle me this.

Working with a new X:One96 Mixer specifically trying to make sense of it’s Soundcard.

I have all of the outputs for the 6 channels routed and recieving audio into Ableton (good start) -The problem arises when I try to capture ‘return signal’ audio.

Picture this:

Chanel 1 - Audio Signal (Soundcard Input 1/2)

Send A - Chunky Reverb

Return Chanel A - Reverb Return Signal (Soundcard Input 9/10)

Through the Master Output I can hear the reverb of course, but in Ableton the signal comes through totally dry. I find that very strange - how can I capture the ‘wet’ return signal?

Thanks
