Considering switching from an Axe Fx II to a Helix rack with controller. Downsides? I really love the control with scribble strips, and for live this will be ideal. Is there a global lead function on Helix yet? With Axe Fx II I can set a global lead that whenever I press on an active patch again, that's my global lead. Extremely useful. Also have reverbs been expanded on the Helix yet?
