I'm newish to loopers and while I've got the basics down and timing I feel like I could take advantage of more features.

First I was curious about connecting additional pedals (Like Boss FS-6). What features could I control with it and if you have it or had it is it worth the buy? I've looked at what it could possibly do and being able to switch the tracks with one hit is tempting.

Second question: Do you use the internal memory tracks live? If so, how do you use them or are they any use to you at all?

Thank you for answering!
