Hi everyone. Mathieu from France, 37. Musician, bedroom producer, intermediate graphic designer and developer. Still learning and getting better thanks to all of you !

I thought about starting a thread for Scriptnode newcommers. I didn't find time to dig into how to contribute to the documentation yet, so this topic would be a "Get started with scriptnode" starting point. I'm not an expert, so please correct me if I'm saying dumb things.
Feel free to contribute to this thread !

HISE version : latest develop branch.

First thing first : create a DSP network :

Create a scriptFx module

This popup will show :

Create a DSP network

Congrats ! You've finally created a DSP network and entered the scriptnode graph editor :

Merry Christmas and happy holidays everyone !

Let's build a "Hello world" Gain Knob :

Once the DSP network created, click into the graph. You'll get this popup showing :

Here you have access to all available nodes

Type in the search bar : "gain" and click on the gain node to add it to the graph :

Here we go :

Done. But let's make this gain knob available in the script editor so you can manipulate it.

Open the parameter control bar by clicking on the little upper knob, then click the "plus" icon to add a control, and name it "Gain" :

Note : When you add a parameter like this, its range is always 0...1.

Although it's possible to leave the knob's range as it is, the logical thing to do here it to modify the range of the knob.
Right-click on it to access its setup :

And change the min/max values like this, and click outside the box to close it.:

NOTE : You can access the setup of every node and parameters by right-clicking on it.

Now click on the target icon to acces the "connect" mode...

... and click'n'drag a cable from the control to the parameter you want to manipulate (here the gain parameter) :

Then click again on the target icon to exit the "connect" mode.

Now, how to manipulate the gain via script ? :

In the script editor, create a generic script reference of the ScriptFX module :

const var ScriptFX1 = Synth.getEffect("Script FX1");

Create a slider in the interface editor, and don't forget to make its min/max values the same as the network's parameter (here : -100...0, since it's a gain knob) :

And create a custom callback for this slider.

Now you can access the network's parameter like any other in HISE :

inline function onknobGainControl(component, value)
{
	ScriptFX1.setAttribute(ScriptFX1.Gain, value);
};

Content.getComponent("knobGain").setControlCallback(onknobGainControl);

Here I did it by script to show how it works but you can also do it within the Interface editor.

Voila ! You got yourself a nice little gain knob made with scriptnode. You can now start noodling around.

To be continued...

Happy New Year everyone !

@ursbollhalder jumping in : export animation as PNGs with blender and (I personnaly) use this to stitch them up : https://www.wavesfactory.com/blog/posts/strip-generator/

Ok now, let's take a look at the container.split node which creates parallel signal chains.

Let's build a little reverb wit a Dry/Wet control :

Add a container.split node to the graph and add 2 container.chain nodes. These will contain our stuff :

See the signal cables ? You can see that the whole signal is send to both the DRY and WET containers and not split into left and right as in the previous example.

Now add the required nodes like this : 1 gainNode for the DRY channel and a reverbNode + a gainNode fot the WET channel (type "reverb" in the serach bar to find it) :

Now will be a good time to introduce you to another type of containers : the container.modchain. This one is here for you to put all your modulation nodes in. It can contain oscillators for LFO purposes, envelopes and more.
Here we'll just use it to handle the Dry and Wet levels and for this, we'll use a nice and handy node that Christoph's provided : the Xfader node.

Add a DryWet control at the top, a container.modchain + a control.xfader to the graph :

In the Xfader menu, select "RMS" and connect everything like this :

Done ! How simple is that ? Now if you want to build you own reverb and manipulate it via your interface, just create parameter controls and connect everything :

Keep in mind though to take care of the control's ranges, depending on whether you're controlling linear values, levels, frequencies, etc...

That's all for today, have fun !

Let's go a bit further and create a L/R balance knob. This example is only here to demonstrate the L/R signal manipulation. Althoug it will be usable, a proper L/R balance control would need a bit more work than that .

How to split the L/R channels ?

Let's start a new network and add a container.multi node and rename it "ChanneSplit" :

(Reminder : to rename nodes : right click on the title bar)

Now, add a gain node and duplicate it with Ctrl/Cmd + D :

See the cables which connect every nodes ? this is your signal flow. Follow it and you'll never be lost

Now we'll add aparameter control, and set its range to -1...1 :

Connect the Balance control to the 2 gain parameters :

But in order for this to work, we have to modify the range of one of the gain parameters since we want the Balance control to handle both the L/R levels.
Lets give the gain nodes a proper name and invert the rightChannel's gain values - node values AND connection values - from (-100...0) to (0...-100) :

And voila again. Now you know how to split the left and right channels.

@Natan I'm using last develop version. A snippet won't help much because it's not a script-related function, but here is the option you have to enable before compiling HISE :
.

Once done, just save your factory presets within HISE and they will be automatically set as 'Read-Only' when you compile your plugin.

@yall if you're still learning HISE - we all are but - you should really subscribe to David's patreon page. You'll get solid basic fundations and your level will increase dramatically : https://www.patreon.com/davidhealey/posts

@ursbollhalder I once found a plugin on blendermarket to export the filmstrip directly but I found it a bit glitchy depending on the resolution of the PNGs

@lalalandsynth @Christoph-Hart @UrsBollhalder loading IRs into scriptnode actually works but only if you have AudioWaveforms tiles into your GUI. Like this :

Add External AudioFile Slots to the filters.convolution node :

Link the AudioWaveform tiles to the nodeConvolution FX + set the correct sampleIndexes :

So the user can load custom IRs into a scriptFx, but it only works this way (or am I really missing something ?).
I couldn't find any way to load them with a comboBox.
The thing is, when one is using the Convolution Reverb Module, we must declare a reference like this :

 const var ConvolutionReverb1 = Synth.getAudioSampleProcessor("Convolution Reverb1");

But this doesn't work (obviously) with a convolution node, so we can't use the AudioSampleProcessor.setFile() function.

@danh on windows yes (when the workbench is in a good mood) / macOs nope.

@d-healey linux only or other platforms ?

Agreeing with @UrsBollhalder, I'm so happy @Christoph-Hart implemented this system into HISE. I so love the scriptnode system ! Keep upgrading it Christoph, thank you very much

@lalalandsynth here you go : https://docs.hise.audio/working-with-hise/menu-reference/export/index.html#export-pooled-files-to-binary-resource

@dustbro sending you here :

Snex_node Needs to be wrapped into a compileable DSP Network

We discussed the matter, but long story short : jdsp.delay and fix8.container.

For the sync there is a control.tempo_sync node available

Is there a node that has a longer delay time than 1000ms

jdsp.delay >> right-click on the 'DelayTime' parameter and adjust the maxValue

I personally use Affinity publisher

@Matt_SF said in How to prevent the preset browser from closing after a selection?:

Would that mean the presets you make within HISE are automatically set to 'Read-Only' ?

Confirmed : Save your presets within HISE to set them as 'Read-Only'.

Note that the preset banks you create are set to 'Read-Only ' too : it means that if you anticipate (like I did) and create an empty "User Bank" for your end user, he won't be able to save presets within this folder.

@Jerems134 I guess you've worked it out since then but if someone is looking for a solution : with cycles in blender there's an option to turn a plane into a 'shadow catcher'.

@natan put the .loadFile in the changeNumSample function - or whatever I named it (Sorry, i just arrived at home to my family and my wife will kill me if I start my computer )
