Possible to communicate between plugins?

[A Former User]

Guys sorry about my ignorance.

What are the use cases of the communication between the plugins?
What does this feature stand for?

[ulrik]

@harris-rosendahl in my case I wan't to send midi information from a multichannel arpeggiator (which will not work in some daws), to several "receiver! plugins to control multi instruments

[lalalandsynth]

@ulrik Could I for example control a gain module on track 2, and having my main control module on track 1?

[Christoph Hart]

@lalalandsynth Be careful about "persistent" states in conjunction with OSC, this is one of the main drawbacks I found in this protocol because restoring these settings from a DAW project will not restore the values (especially because you can't guarantee that the gain module 2 exists already when the gain module 1 is created and restored).

[ulrik]

@lalalandsynth
If I understand you right, yes

In you main plugin

const var rm = Engine.getGlobalRoutingManager();

rm.connectToOSC({
	"SourcePort": 6666,
	"TargetPort": 6667,
	"Domain": "/receiver"
}, function(printError)
{
	Console.print(printError);
});
//     In you gain callback
inline function onGainControl(component, value)
{
      rm.sendOSCMessage("/gain", value);
}

Content.getComponent("Gain").setControlCallback(onGainControl);

In you receiver plugin

const var rm = Engine.getGlobalRoutingManager();

rm.connectToOSC({
	"SourcePort": 6667, 
	"TargetPort": 6666, 
	"Domain": "/receiver"
}, function(printError)
{
	Console.print(printError);
});


inline function OSCCallback(id, value)
{
	Track2Gain.setValue(value);
        Track2Gain.changed();
};

rm.addOSCCallback("/gain", OSCCallback);

@Christoph-Hart while searching the juice files for a solution to the "locked port" issue, I found this:
taken from juice_OSCReceiver.h

/** Use this struct as the template parameter for Listener and
        ListenerWithOSCAddress to receive incoming OSC data immediately after it
        arrives, called directly on the network thread that listens to incoming
        OSC traffic.
        This type can be used by OSC callbacks that don't do much, but are
        realtime-critical, for example, setting real-time audio parameters.
    */
    struct JUCE_API  RealtimeCallback {};

If this was implemented in Hise, would it be able to control midi messages accurate, in time?

[Christoph Hart]

@ulrik I'm using the Realtime callback already (unless you specifically tell the OSC listener to be asynchronous).

[ulrik]

@Christoph-Hart Great!

[ulrik]

@ulrik I managed to have several listeners plugins, by forwarding the not consumed data to a new port it works.

The downside is that if I want to listen to ch 4, I need to have ch 1 - 3 also up and running

const var rm = Engine.getGlobalRoutingManager();

inline function onChannelKnobControl(component, value)
{
	rm.connectToOSC({
		"SourcePort": 6666+value, // incoming port
		"TargetPort": 6667+value, // sending port
		"Domain": "/ostarp"
	}, function(error)
	{
		Console.print(error);
	});
};

Content.getComponent("ChannelKnob").setControlCallback(onChannelKnobControl);


inline function OSCCallback(id, value)
{
	local ch = ChannelKnob.getValue();
	
	if (value[0] == ch)
	{
		local ev = Synth.addNoteOn(value[0], value[1], value[2], 0);
		Synth.noteOffDelayedByEventId(ev, value[3]);
		
		LogPanel.setValue(value);
		LogPanel.repaint();
	}
	else
		rm.sendOSCMessage(subdomains[ch-1], value);
};

for (i = 0; i < 4; i++)
	rm.addOSCCallback(subdomains[i], OSCCallback);

[ulrik]

@Christoph-Hart is there a way, in Hise, to count how many instances of the same plugin is loaded in a daw?

The above solution is not optimal because the user will not be able to run more than 1 instance of the "mother plug" before it's get messy.

I'm thinking maybe the second "mother plug" could sense if there is another loaded and automatically change the domain port and the listeners have a way to change the domain port (via the user)?

[ulrik]

@Christoph-Hart
I still haven't found a way for instance number 2, 3 etc, to connect to the target port (if already 1 instance is communicating with it).

Do you have any suggestions what I, (or you ) could do to make it work?

[Sac Ten]

Here is a way to communicate between plugins,
without OSC messages. I found out before I saw this post. ;)

You could probably use the server calls to make it work over the internet :p
