Helix Looper Needs a Fadeout Stop Option in Helix Posted December 6, 2017 Just bought the Helix. Love it. I use a Boss RC-300 looper through the effects loop which has fade out. I use the fade out all the time. Seems like the Helix looper is not useful for live playing (unless you do the expression pedal thing described above.) Looper is fine if just recording a track though. Hoping they come out with fade out (AND fade in) in next update.
