Evening, all. I've been trying to set up live looping on MainStage 3, following this article (https://beatbars.com/blog/live-looping-with-mainstage-2.html) so that I can loop multiple instruments . Right now, my setup has one Aux Channel Strip, the default piano, and some synth. The Aux Input is Bus 15 with Loopback, and the instruments are being sent to Bus 15. When I try to map a key, however, the Aux Channel doesn't show up. Has there been an update since the article? Have I made a mistake along the way? Thank you.
Edit: Fixed my problem. The Aux Channel was a patch with a channel strip, not a channel strip within the concert. Thanks.
