SNEX nodes - Waveshaping / Saturation / Distortion?

[ustk]

@dustbro try putting this in the getSample function (which in fact can be any other function you call from this one)
Just don't forget the SNEX language rules (i.e. the float numbers)

getSample function

Looks like this is the spot.

float getSample(float input)
	{
		input = (1.0 + 0.5) * input / (1.0 + 0.5 * Math.abs(input));

		return input;
	}

I've added a parameter to the snex module. How do i reference it in the script?

[ustk]

@dustbro

float gain = 0.0f;

float getSample(float input)
{
	return (1.0f + gain) * input / (1.0f + gain * Math.abs(input));
}

/*

*/

template <int P> void setParameter(double v)
{
	gain = (float)v;
}

This works if you have only one parameter, although if you have more then you'll need an enum to find which one is moved so you set the right variable

@ustk got it. Thanks!!

Is anyone able to compile a SNEX node to dll?

I'm getting this error from VS2017 and wanna make sure it's not just my rig

@dustbro I've compiled a script fx to .dll but it didn't have a SNEX node in it (in case that helps! :face_with_tears_of_joy: )

Same here. I can compile script FX that do not contain SNEX nodes.

[DanH]

@dustbro out of interest can you export a plugin that has a compiled .dll in it?

[Dan Korneff]

@danh I can. It MOSTLY works pretty well ;)

Do you get the "frozen" icon on your compiled nodes ? Here I can wrap the network, compiling it doesn't show any errors (seems to go well) but HISE is not using the compiled node.

BTW I didn't try to compile a SNEX node yet because I'm not smart enough ATM to understand how to write SNEX code

I do. Just not on SNEX nodes. You have to use commit 9935411bb9bfcd4be583c93143121ccb75c57fc5 or newer for scriptnode compilation to work.

@dustbro I'm on the Dec. 22 commit but I'll try this one, thanks !

[Dan Korneff]

cannot convert 'this' pointer from 'T'

@Christoph-Hart It looks like and issue the parameter data from the snex nodes. Anything I can do to remedy this?

Edit:
Just did a quick text. It appears to only affect the snex_shaper node. I was able to successfully compile the snex_node.

[Christoph Hart]

@dustbro Good catch, should work now.

[Dan Korneff]

@christoph-hart Thank you!

[orange]

@dustbro Just to follow up, does the snex_shaper node can be compiled as a dll DSP network?

It crashes here.

[Dan Korneff]

@orange I'm able to compile SNEX_Node and SNEX_Shaper here.

[Dan Korneff]

@orange Beware, it's very picky... I have to compile the DSP dll in debug mode to sort out issues. Eventually it works

So it is still buggy then. Ok I will try the debug mode thanks

Can use a debug build dll in a release build plugin?
