I want my Boss RC50 Looper in a signal chain after the Helix. Right now, I'm running the Helix straight into the mixing board. If I put the RC 50 into the FX insert, when I change the preset in the Helix, it changes the sound of the loop, which is what I don't want. I would like the RC 50 post Helix so that I can keep tracks from changing when I loop a different sound. But the RC 50 doesn't have an xlr in and out where I can route straight into a mixing board. Any suggestions?
