Is this still the case or has anything changed in the meantime? I also thought pressing the large hotswitch button on the unit itself would behave just as perssing the hotswitch button in the H9 control? I was figuring out how to save that hotswitch press to the unit itself but apparently this can only be used by hooking up an extra aux switch or midi?

Currently, the Hotswitch can only be triggered by an external aux switch or MIDI
