Great question, i was wondering that too about the HX Stomp, it sounds like the Helix Floor has WAY more real estate
for Setlists. That's ok though, the HX Edit can librarian everything into folders by using Import /Export, just like saving tracks on a DAW. Gawd knows i have a lot of file folders on the desktop of my old lap top.
The good news is Effects Patches are really small in comparison to saving a CD worth of File transients for music !
