Hey, Andrew. No announcements or new developments with looping, currently. We'd be happy to have you as a beta tester for Chorus, however.
If you do have a looper pedal, you can run it with TWA. You can run guitar>looper>TWA to hear the loops through your guitar, or you can run guitar>twa>looper>amp.
Shoot us an email at firstname.lastname@example.org, tell us you wanna try it out, and the only thing we ask in return is your feedback.
So....... what would happen if I were to stick any other effects pedal in the guitar>looper>TWA chain? Could I stick a different pedal in place of the looper?
