How do you use Global Cable?

[griffinboy]

Hey guys,
I'm wondering if anyone can quickly explain how to use:
GlobalCable.registerCallback(var callbackFunction, var synchronous)

It's a line that I found in the documentation, but I'm not sure how to use it.
I am trying to use an LFO that I have programmed in scriptnode, to control a Parametric EQ.
I assumed the best way to do this would be to send the LFO out of scriptnode, using a global cable, and then updating the Parametric EQ whenever the global cable gets updated.
I have successfully sent the LFO through the cable, and I've got an ID for that cable, but I am stuck on how to create a callback for the cable.

Please, and thanks : )

@griffinboy I haven't been able to find other posts that ask about the Global Cable, but perhaps I haven't been searching the right keywords.

@griffinboy check the data visualisation snippets, there is an example usage of the global cable

Thanks, I'm sorry to ask this but where can I find these snippets?
I've searched through the forums, documentation, and the HISE tutorial files and couldn't see any mention.

Struggling to get it to work, I don't really understand the example code that I'm trying to port.

@griffinboy you need to connect the mod output to the Value parameter of the global cable node, it doesn't read the audio signal.

@Christoph-Hart
Thanks I've hooked that up now!
The thing I'm trying to figure out is how to make a callback that uses my global send node.

I'm still a little confused about how this works in HISE. I've tired to adapt the example that I found in the example snippets, but I've probably butchered it.

[Christoph Hart]

@griffinboy ah just realized you‘re using the wrong node. Use a global_cable node - the global_send node is used to route audio signals not a single parameter event.

@Christoph-Hart
Hell yeah!
Thank you it works perfectly now.

And my callback works too.
I shall now have to find out why it works
I probably need to look into HISE syntax more

@griffinboy

I'm quite curious about what this part does

You can either register it as synchronous callback or as asynchronous callback. The latter will filter out repetitions and will be called on the UI thread.
