Is it possible to link parameters between plugins?

[Bicrome]

Hello.
Can i link the same parameter between plugin instances? The most basic example of what I mean is the Blue Cat's Gain Suite, which lets you add each plugin instance to a group, and that way all of the instances of the same group will have the save settings.

What's the easies way to achieve this?
Thanks.

@Bicrome This is a very good question that hasn't been raised for a while. I think brands who are doing this are using specific pipe/thread communication.

@aaronventure did it using OSC protocol:

as well someone else way before that I can't remember...

@ustk OSC doesn't work. You need to write to a file and read it on a timer. It's dirty as hell but it works.

Named pipe or some other memory-based solution would be much better, though, and a lot faster (no filesystem access needed).

Named Pipe idea

@Christoph-Hart This is my entire class. It works great. I have a value change broadcaster for all my controls, and it checks for the condition (key modifier...

@aaronventure I used a file based communication a long ago but it was too dirty, I reckon @Christoph-Hart said it's a no no and possibly advised for OSC, but here my memory is fading… and if you did not succeed then it's a dead end for me

@aaronventure Sick concept. Im gonna have to try this out for myself.

@ustk it's just a nono for realtime communication, if you are exchanging a non-realtime state then it's fine.

But instead of the named pipe thing I could also repurpose the web socket function that I slapped onto the Webview, this would also give you network communication abilities in addition to local data communication.

@Christoph-Hart said in Is it possible to link parameters between plugins?:

give you network communication

Excellent, I can have a lan party with my snake game :)

Thanks for all of the answers!

@Christoph-Hart And how hard would it be to impoement and use the web socket from Web view?

Writing to a file seems like a very dirty solution indeed hahaha, but what i was searching for with the plugin linking ability was to build something personal, only for me, so that mixing in ableton would be a bit better (i dont have m4l sadly). That means that I dont care what the solution is if it gets the job done on my machine, at least now.

So, what should I go for? Or should I wat a bit? I'm not a programmer so even tho I know maths and some basic c++, dealing with a whole comunication thing might be too much for me.

@Bicrome I made an attempt long ago, had several "client plugins" listening to the main plugin, It worked using osc.
I stopped working on it but I don't remember why.

Here I wrote about it:
