Orba 2's looper is similar to the original Orba's four-track recorder (you'll see we kept it simple), but you can overdub up to 128 bar loops (up to 5 minutes)!
It might help to watch this video to get a sense of how the looper works:

The Orba 2 app will also allow you to quantize your modes and choose from tons of sounds not available on the original Orba.
More info on using the Looper can be found in the online User Manual.
