I have this common situation:

I have an abstraction which has a parameter control visible to the parent via graph-on-parent. Let's call the parameter $0-FOO

I want the user to be able to adjust the control via the GUI.

I also want to be able to drive $0-FOO via an inlet or a message.

And when that happens, I want the knob in the GUI to update

and show the current value.

When I set up

[inlet] -> [hsl]

Now the [hsl] cannot be moved via the GUI.

I am trying to find a way to solve this.

One possible solution is gate the inlet with a [spigot]

which would work if I could detect if something was
connected to the inlet or not.

Q1: Is there a way for me to tell, inside an abstraction,

whether something is connected to a particular

[inlet] or [inlet~]?

Q2: Or else how can I read the output of a control (e.g., hsl)

and drive it also? (this sounds like an application

for a syncho/servo)

Thanks!
