Scripnode 101

[Matt_SF]

@dustbro use a math.mul node and set the value to -1

[ustk]

@dustbro As @Matt_SF said, *-1 is the way to go

[Dan Korneff]

Thanks!
Should nodes like Tempo sync and PMA need to be placed in a modulator chain?

[Matt_SF]

@dustbro no need, you can put them in the graph as is (or put them in a container.offline)

@christoph-hart said in Scripnode 101:

What the modchain actually does is creating a monophonic and downsampled signal which will not be fed into the original audio signal and thus is suitable for modulation if you put a core.peak at the end of its nodes.

[Dan Korneff]

@Christoph-Hart is there an equivalent to Engine.getSampleRate() in SNEX? I'm getting an error saying it Engine can't be resolved. Come to think of it, Console.print() doesn't work as well. it's supposed to, right?

[Christoph Hart]

@dustbro No but you can use the prepare function to store it to a member variable:

void prepare(PrepareSpecs ps)
{
    sr = ps.sampleRate;
}


double sr = 0.0;

@christoph-hart Thank you!

Okay some beginner scriptnode questions for you all.

What's with the beaker glass?

What is the best way to access scriptnode parameters? Create a midi script above the scriptnodeFX like this? If I have logic for callbacks having to do with the scriptnodeFX is the midi script controller script where I should put it?

Also if possible we should rename this thread "Scriptnode 101" rather than Scripnode 101 so it comes up in a search.

No tips on how to best access script node parameter's from midi processors?

[crd]

Okay more basic scriptnode questions, what is the difference between creating a embedded dsp network and creating a new DSP network file? (The 3d square vs. the page with a corner turned graphic on the scriptnode front page.)

[d.healey]

@crd The embedded one is part of your project XML, the network one is a separate XML that can be compiled to C++ or shared with other projects.

[crd]

@d-healey What would the advantage of ever using the embed one? Is that for smaller scripts?

[d.healey]

@crd Useful for prototyping and for small scripts that you don't plan to use in other project and that don't need compiling.

Has anyone successfully exported a plugin with a script node network/dll?

I was able to export for a while without compiling a dll but now I am getting an error:

and the script node workbench crashes whenever I try to compile wrapped dsp nodes into a dll.

[Dan Korneff]

@crd I'm successfully exporting scriptnode plugins with compiled dll.

What's the best way to access L/R inputs to process them separately in SNEX?
Can we use arrays in SNEX?

@Christoph-Hart is there an example showing how to use block?

block - a wrapper around a preallocated buffer of float numbers

When I try to initialize an index of a block with a number, I get an error saying statement cant be parsed.

[ustk]

@dustbro got it to work for the left channel only, it might be obvious why data[1] isn't working but I can't find...

	// Process the signal here
	template <typename ProcessDataType> void process(ProcessDataType& data)
	{
		for (auto& s: data[0])
			s *= 0.5f;
	}

[ustk]

@dustbro oh I finally found a solution

	// Process the signal here
	template <typename ProcessDataType> void process(ProcessDataType& data)
	{
		auto frame = data.toFrameData();
		    
		while(frame.next())
		{
			frame[0] *= levelLeft;
			frame[1] *= levelRight;
		}
	}

[Dan Korneff]

@ustk Thanks! What about the function to process the input?

For instance, the SNEX shaper has:

float getSample(float input)
{
       return input;
}

Anything other than float input returns a parse error.

[Dan Korneff]

@Christoph-Hart is there a simple example that shows how to do this with an SNEX node?
