What is a way around button callbacks not working when they're assigned to a processorId?

[Orvillain]

So I don't think this is a bug, I think this is just me not understanding something. Basically I have a button that is assigned to a processorId - because when the button is on I set a DSPnetwork parameter to 1.0, and when it is off, I set it to 0.0.

But when you assign a processorId in this way, button callbacks stop firing off. I'm sure I've read on the forum that this is intentional.

But my question is, how do I work around this??

As of yet, I've not actually managed to set a DSPnetwork parameter to a value from my code. Don't know if I'm just failing hard there; if anyone has a snippet, that would be much appreciated!

Is this where I have to get into broadcasters, so I can broadcast my button state to multiple places at once???

Any other thoughts?

Think I answered my own question.

*Value changes
On the first look this doesn't sound particularly interesting because the value callback was already accessible through setControlCallback() , however if you're using processorId / parameterId properties it will not fire so this gives you the chance to add additional, "non-exclusive" callbacks for UI things

See: attachToComponentValue()*

This is the usual way, but broadcaster is also a good choice.

Yeah I've tried it before, and things weren't flushing through properly. That was earlier in the week though, and a lot of coffee and sleep deprivation has passed through my brain, so I can't really remember the details!

I think I'll investigate the broadcaster approach, because it seems really useful.

fxReference.setAttribute(fxReference.parameterName, value) is not working for you?

You would call this from the knob callback.
