The Helix expression pedal is killing it on volume swells! I just wanted to take a second to say how amazing volume swells on the Helix sound with the volume pedal block's "Curve" parameter set to "Logarithmic". I am getting extremely musical violin-like swells with zero effort; no capoeira, ninja, or dance skills required. Really effortless and sweet sounding. These are the best sounding and easiest to create "violin" swells of any expression pedal I have ever tried. Something I only use on a few songs but it sounds superb!
