Hell-o dear Helixies ! We recently purchased a Helix rack and wanted to use a Engl z12 midi pedal board with it. It seems to work somehow but we can't assign certain presets or snapshots to the FootSwitches. Is it even compatible with the helix? In the manual it says that the helix works with midi pedal boards I know, the easiest solution is probably to just purchase the helix control pedal board.. but .. You know.. Why not use what we have? I hope anyone can help :) Cheers!
