Considering getting a Helix Rack. I've looked through the manuals and I can't really get an answer to what I'm looking for. I know it's possible to set a wah with an auto-on function with an expression pedal, but is it possible to link other effects to the auto on function simultaneously? For example, could I set the exp pedal movement to turn on the wah along with a compressor and delay without having to use a controller button to engage them first? Has anyone tried this?
