Scriptnode filter.convolution – select External Audio File Slot from UI (ComboBox)?

[David Healey]

@filipalex96 You don't need multiple slots for this, you just need one, and you use the combo box to load a different IR into that one slot.

Thanks, that makes sense.
Could you please explain how to actually do this with filter.convolution in Scriptnode?

More specifically:
– What is the method / API to load a new IR WAV file into the convolution node at runtime?
– Can this be triggered from Interface Script (e.g. from a ComboBox)?
– Or do I need to expose a Scriptnode parameter / use a specific node to call something like “setFile” on the convolution?

A small example or hint would really help. Thanks!

@filipalex96 Instead of getting the reference to the effect with Synth.getEffect you need to get it as an AudioSampleProcessor. That will give you access to a bunch of extra functions.

Thanks a lot for the tip, really appreciate it!
I didn’t realize I should access it as an AudioSampleProcessor instead of using Synth.getEffect(). That makes a lot of sense.
I’ll try this approach and see how it goes. Thanks again for the help!

@filipalex96 Thanks again — I’m very close now.
I call Engine.loadAudioFilesIntoPool() and setFile() works in principle, but I can’t get the correct reference via Synth.getAudioSampleProcessor("...").

In my Scriptnode network the convolution node is labeled/ID like “convolution_verb” (see screenshot), but Synth.getAudioSampleProcessor("convolution_verb") doesn’t seem to resolve.

Question: what exact name/ID should I use in Synth.getAudioSampleProcessor() to reference the Scriptnode convolution “Single Sample” loader? Is it the Scriptnode node ID, or the module ID somewhere else?
Any quick way to list available AudioSampleProcessors / their IDs from script?

Right click on the header of the script effect and select it.

@David-Healey Hi again, thanks for the suggestion! I think there’s a misunderstanding on my side:
I’m not using the classic Convolution Reverb FX module. I’m using Scriptnode → filter.convolution inside a ScriptFX network.

However, from Interface Script:

Synth.getAudioSampleProcessor("Script_FX1") exists (auto-generated by HISE), but calling Script_FX1.setFile("SomeIR.wav") does nothing (IR does not change).

fx.getNumAttributes() is 0, and I also don’t have getNode() in my build, so I can’t access the node directly.

@filipalex96 I'll make a snippet for you in a bit

[filipalex96]

@David-Healey thank you soo much

[Chazrox]

@filipalex96 fix your 'const var conv' to 'const var'

[David Healey]

@Chazrox Variable needs a name

@David-Healey ahh duhh. long week. smh. I'll take 2 shirts please.
