Thats just a bad reflection of the controls - I would expect a set of
MOMENTARY controls for that situatuation (like on a hardware box).
No host has any chance of correctly interpreting that situation - someone
else could declare the same thing and reasonably expect it to be something
completely different (e.g. a slider that resets back to its default
position when released, like a pitchwheel).
I also dont like overloading the behviour of default to mean "not the
defualt" if the control is MOMENTARY hinted.
