Scriptnode: Granulator

[Christoph Hart]

@FatMitchell Yes, just set the audio file slot to external, then hook it up to an AudioWaveform like you would do with a Looper or Convolution reverb.

Then create parameters for the knobs you want to control and connect it to your UI knob:

@Christoph-Hart How can we control the sample map selection in the granulator from the ui? I can't link a knob to the combo box in the granulator itself...

[Christoph Hart]

1. Register it as external audio file
2. Use the loadFile() method, but with the samplemap wildcard identifier:

const var af = Engine.registerAudioFile(0);


af.loadFile("{XYZ::SampleMap}MySampleMap");

[DanH]

@Christoph-Hart should it be:

const var af = Engine.createAndRegisterAudioFile(0);

?

[Christoph Hart]

@DanH yes I just typed it out of my head...

[DanH]

@Christoph-Hart Forgive the noob questions on this, I'm coming into it very cold.

What does the XYZ::SampleMap part of the wildcard refer to?

Essentially I'd like to select the sample maps in the Granulator with a combo box

[mrfurniture5e]

just set the sound record opening to outer, then, at that point, connect it to an Audio Waveform like you would do with a Looper or Convolution reverb.

Then make boundaries for the handles you need to control and associate it to your UI handle.

Thanks

@mrfurniture5e amazing....

[Christoph Hart]

WTF? When a spam robot starts to post working answers to a super specific problem you know the uprising isn't far.

[DanH]

@Christoph-Hart any chance of an actual answer to the question though?! :face_with_tears_of_joy:

[Matt_SF]

@DanH isn't it simply :

af.loadFile("{PROJECT_FOLDER}MySampleMap.xml");

?

[DanH]

@Matt_SF I hadn't tried it - I thought it was a different kind of wildcard :man_facepalming:

Thanks, will give it a go now :)

[DanH]

@Matt_SF Do you have any idea how I use this to select the sample map within the Granulator?

[Matt_SF]

@DanH I didn't try it but I guess this should work (thanks Christoph!) :

const var g = Synth.getAudioSampleProcessor("ScriptGranulator");

const var sMapSlot = g.getAudioFile(0);

sMapSlot.loadFile("{PROJECT_FOLDER}MySampleMap.xml");

Don't forget to setup your granulator node so it uses an external slot :

For the loading of audio files, you can also take a look here, the process is similar :
Changing Impulses in Scriptnode.

[Christoph Hart]

Nononono, the {PROJECT_FOLDER} wildcard only works if you use it to load a sample map into a sampler. For audio files slots it's different:

You can basically load three things into an AudioFile slot and it tries to figure out what you throw at it based on the wildcard (or other things).

• a single audio file. This is where you can use the {PROJECT_FOLDER} wildcard to reference the embedded audio files (or the project's AudioFiles folder).
• a SFZ file. Then you need an absolute path with the file extension .sfz
• a samplemap. Then you need the wildcard {XYZ::SampleMap} - like, literally: XYZ::SampleMap) :)

The XYZ in this wildcard means a 3-dimensional mapping (Notenumber, velocity and RRGroup) and is used in the HISE codebase whenever an audio file loads a sampleset with multiple samples.

[DanH]

@Christoph-Hart haha, I just figured you had written a generic example .

[Matt_SF]

@Christoph-Hart OK thanks for the clarification! I referred to the [documentation] (https://docs.hise.audio/working-with-hise/project-management/projects-folders/sample-maps.html) but it is indeed for the usage in a sampler

[A Former User]

@Christoph-Hart Rather than a sample player, would you like to add a time stretch node with incoming audio process?

[DanH]

@Christoph-Hart ok so how do I load this into the actual granulator?

I tried this (cobbled together via the convolution thread) but I assume it's meant for audio files rather than sample maps... I get an 'object' loaded into the single sample window as opposed to anything in the sample map one. Do I need '.xml' at the end of the loadFile string by the way? I assumed not...

const var g1 = Synth.getAudioSampleProcessor("GRANULATOR1");

const var af = Engine.createAndRegisterAudioFile(0);

af.loadFile("{XYZ::SampleMap}AAB303-PROTON");

inline function onComboBox1Control(component, value)
{
	g1.setFile(af);
};

Content.getComponent("ComboBox1").setControlCallback(onComboBox1Control);

Thanks! :)

[Christoph Hart]

@DanH well, you pass in the object reference to g1, but I'm amazed that it actually worked and displays the object pointer :)

You need something like this in the control callback:

af.loadFile("{XYZ::SampleMap}" + component.getItemText());
