YouTuber Edward Spiegel did a highly detailed tutorial on setting up a mega looping station with Loopy, Audiobus, and AUM. The video description includes links to more tutorials from Edward.
Video Description:
This video demonstrates using Loopy as a multitrack looper recorder/player from inside AUM. You can do everything you need from AUM's main interface. No need to switch apps or go menu diving to record and play your loops.
This video shows a typical session. Other videos teach you how to set up your session and the AUM mixer and how to use the Audiobus palette to control in more depth than is covered here.
