I have a knob (knobTest) that can have values from 0 to 2. It sends out a sysex message that includes the knobs value.
It works fine on its own.
There is a momentary button that is its supercontrol (stepTest) which is a stepper.
When stepTest is tapped, knobTest sends its SysEx.
HOWEVER, if I add subcontrols (a button group) of knobTest, I haven't found a way for it to send its sysex. Its subcontrols are really just for display (colored momentary buttons whose color indicates the knob value). (I would actually love for the subcontrols to actually not send anything but that doesn't seem to be an option)
I have tried every combination of sub and supercontrols and cannot find a way to get knobTest to send out its sysex when it has this button group as a sub.
