I have a Supercontrol button set to "momentary." It activates two subcontrol buttons. When the momentary supercontrol button is tapped, both subcontrols behave as toggle buttons, staying on. Tapping the subcontrols turns them back off. I read that subcontrols take on the properties of the supercontrol, but I can't make that happen. Even manually setting the subcontrols to "momentary" doesn't work. What am I missing? Thanks.
