One preset/song works fine, and it’s what I’d have done, because it’s the digital equivalent of what we’d do with a pedalboard and amp. Almost all of us have been there.
Digital opens doors for us that we have to think about, how can we best use the new features. How can we use set lists if we’re not gigging? It’s not as easily seen, but messing with the Setlist manager and getting familiar with it certainly started my wheels turning.
Even a solo artist, such as someone working wedding gigs, could take advantage of the features, so dig in and see if it fits in an unexpected way.
