a phasing sound with a looper / Ableton setup is generally the result of an input being both directly monitored AND monitored through Live. I would guess you have your loopers set up with the Input > Output setting at something besides “Never”, while also having the input monitored either through the mixer or your interface.

If there’s a way to do it, could you please post a diagram of your entire setup? And if possible, find a place to upload your Ableton patch so we could examine it? I do similar stuff with Ableton all the time and am happy to help, but it’s tough to tell where you’re going wrong with the information provided.
