So what does the TRIGGER hint mean? For a normal gate CV signal (which I
think is what youre talking about) there is no need for a hint.
I dont see how you can have a momentary control which is anything other
than boolean, you press it, the signal goes high, you release it, it goes
low. I dont see hoe you can fit a variable amplitude in there, something
like a slider or knob has no momentary action.
