HX effects: external up/down switch...hints in Helix Posted September 28 Not sure I understand the scheme here, but if you are referring to only HX FX, you could send a ALL BYPASS command via MIDI Controller, then all the commands assigned to the HX FX footswitches will keep working, as Bypass only affects audio through (but as soon as you press a FS the global bypass will auto lift). It's a weird use of the HX FX, as you would basically use an external midi controller, to then use the HX FX as another midi controller, but I'm sure I'm missing something here. :) EDIT; clean, clean+, crunch, crunch+, lead, lead+. These are looking perfect things for a proper Snapshot setup. Using a dedicated preset for each of those states, will produce signal drops between presets (because of the DSP flush).
