Helix Bug Reports in Helix Posted August 8, 2019 Hey all. hxs In 2.81 I cant get f4 to work with my current presets. I backed it all up and am using the set lists that I already made previously. When I press it, it mutes everything and I have to turn down the volume pedal (exp 1) and back up to get it back on. I tried deleting and rebuilding the assignments with no luck. Anyone else have this issue?
