Orba's looper is essentially a four-track recorder (you'll see we kept it simple), but you can overdub as many times as you like.

The companion app will allow you to select new songs, sounds, and settings. Orba's surface will adapt to whatever you have selected in the app.
More info on using the Looper can be found in the online User Manual.
