ScriptFX Parameter Example?

[A Former User]

Are there any examples available for the old (pre-scriptnode) ScriptFX stuff? Specifically how to attach a Parameter Slider to the actual DSP in the processBlock?

Continous Noise and Sine wave generators in fx plugins....

Now it is :) Check out this example patch: It's a monophonic synthesiser without any sound generator :) HiseSnippet 1700.3oc0X0zaaTDFd2DuPsCAZQbgaqhDRNpgH61T...

@orange Thank you but this is specific to the pre-built libraries, I need to access a custom variable in the processBlock:

function processBlock(channels)
{
	for (c in channels)
	{
		for (s in c)
		{
			s = s + (Math.abs(s) * scalar); // i need "scalar" as a param  to connect to the frontend
		}
	}
}
 

Not sure where to instantiate it, and what type ie reg/var

ah okay i can just add them like a regular script and reference them in the processBlock, super easy, thanks again!

@iamlamprey Is there a reason why you still need to use this old approach? Especially If you need to process on a per-sample basis, then using HiseScript is super inefficient (it's at least 10x slower than using scriptnode / SNEX).

The example you posted is a one liner using the core.expr node.

@Christoph-Hart I think it's because he is building an instrument for Rhapsody.

Is it possible to keep the compiled networks outside of the plugin by shipping the dll to the user?

@d-healey said in ScriptFX Parameter Example?:

No, I don't feel comfortable declaring this as a feature robust enough to be shipped to end users - the DLL allows fast iteration during the development process but if you want to make it a robust plugin system a lots of things need to be added / tested.

You can recreate this within scriptnode though:

[A Former User]

@Christoph-Hart I've built a backend module-creator to rapidly iterate with the builder class and I haven't been able to get it loading Scriptnode trees, which is why I'm using the older module

If i can load uncompiled Scriptnode trees using the builder that would be awesome

and yeah, it's for Rhapsody

[Christoph Hart]

@iamlamprey If you export the scriptnode module as Base64 state, it's super easy:

const var b = Synth.createBuilder();

const var i = b.create(b.Effects.ScriptFX, "ScriptnodeFX", 0, b.ChainIndexes.FX);

b.get(i, b.InterfaceTypes.Effect).restoreState(

@Christoph-Hart How are you exporting the tree to Base64? Your example works but my exported strings don't load anything

I'm right clicking the root container and using this button:

[A Former User]

ah it's the Edit menu version... okay now it's working cheers

[Christoph Hart]

@iamlamprey either there or you can just call exportState() from a script, this will also give you the Base64 string.
