Is there a way to give a custom c++ node parameter modulation support without wrapping in a network??

[Orvillain]

I've written a bunch of c++ effects, and I notice that they appear as options in the HardcodedMasterFX and HardcodedPolyFX modules, even without wraping them in a scriptnode network.

I was wondering if the parameters can be linked to the wider HISE modulation system, without wrapping them in a scriptnode network?

I have these preprocessor definitions specified in my project:

HISE_NUM_SCRIPTNODE_FX_MODS=32
HISE_NUM_POLYPHONIC_SCRIPTNODE_FX_MODS=32
NUM_HARDCODED_FX_MODS=32
NUM_HARDCODED_POLY_FX_MODS=32

But I'm not really sure what I would need to do in my c++ for the effects, to make this happen... if it is even possible?

Oh, I didn't know that this high number works.

NUM_HARDCODED_FX_MODS=32
NUM_HARDCODED_POLY_FX_MODS=32

Have you already compiled your project with these preprocessor definitions and does it work?

@Orvillain I think you'll only be able to modulate the parameters (aka UI parameter modulation) without the whole MatrixModulation benefits. Also it might not be polyphonic

Yep it does work!

Cool, thank you! :-)

yes, it's a new method that you need to overwrite in your C++ node where you can specify the modulation layout just like you do with scriptnode root parameters. It works similar to the createParameters() callback where you need to populate a list of data objects which will then be used by HISE to setup the modulation scheme:

void createExternalModulationInfo(OpaqueNode::ModulationProperties& info)
{
	// Create a list of modulation slots
	modulation::ParameterProperties::ConnectionList list;

	// Create a modulation connection info object
	modulation::ConnectionInfo slot1;

	// modulate parameter with P==1
	slot1.connectedParameterIndex = 1; 
	// yellow
	slot1.modColour = HiseModulationColours::ColourId::Gain; 
	// only scale (like gain modulation)
	slot1.modulationMode = modulation::ParameterMode::ScaleOnly; 

	list.push_back(slot1);

	modulation::ConnectionInfo slot2;

	// modulate parameter with P==5
	slot1.connectedParameterIndex = 5; 
	// purple
	slot1.modColour = HiseModulationColours::ColourId::Pitch; 
	// bipolar / unipolar add mode
	slot1.modulationMode = modulation::ParameterMode::AddOnly;

	list.push_back(slot1);

	// pass the list to the modulation property object to initialise
	// the first two modulation slots
	info.fromConnectionList(list);
}

Is this the recommended method to use for modulating a c++ node? Works with the matrix modulation system and such? I've been needing to investigate the best way to do modulation.

[Christoph Hart]

@griffinboy yes that‘s how I do it in sbb too.

[Orvillain]

Also, note to self. Don't name your custom c++ node the same name as the network. It won't compile. Dohhhhh.

@Christoph-Hart Amazing! So what I've said is just wrong!
