Hello HISE Community!

I'm encountering an issue while developing an audio plugin, specifically related to applying compression to multiple bands simultaneously. I'm trying to implement a dynamic EQ compressor (similar to TDR Nova), and I want to be able to apply compression to multiple active bands at the same time, with customized settings for each band. However, I'm running into an error when trying to apply the compression settings to each selected band.

Here’s what I’ve tried:

I've created a global array to store buttons for each band (BandToggle).
I’ve used a loop to create buttons that allow the user to toggle bands on or off.
The compressor settings are customized for each band, but when I switch between bands, the compression doesn't apply to all bands simultaneously.
Below is a relevant code snippet for what I’m trying to achieve:

I want to apply compression to multiple bands simultaneously, each with its own specific settings.

Thank you in advance for your help!

@David-Healey thank you soooo muchhh

@David-Healey thank you soo much

@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 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?

@David-Healey said in Scriptnode filter.convolution – select External Audio File Slot from UI (ComboBox)?:

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!

@David-Healey said in Scriptnode filter.convolution – select External Audio File Slot from UI (ComboBox)?:

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!

@David-Healey They’re not connected to anything yet.

I just added multiple External Audio File Slots to load different IRs, but I don’t know how to switch/select the active slot inside the Scriptnode network (or expose it to the UI).

My goal is to select the slot from a ComboBox in the Interface Script.

Hi everyone,

I’m building a convolution reverb inside Scriptnode using filter.convolution.
Inside the node I added multiple External Audio File Slots (IRs) (Slot #1..#6) (see screenshot).

What I want: from the HISE Interface Script / UI, use a ComboBox (or any UI control) to select which External Audio File Slot is currently active.

I tried accessing the Scriptnode network from interface script, but:

fx = Synth.getEffect("Script_FX1") works

fx.getNode(...) does not exist in my build (“function not found”)

fx.getNumAttributes() returns 0 (so I can’t control it via setAttribute() either)

Questions:

Is there an official way to switch the active External Audio File Slot of filter.convolution from UI / interface script?

Do I need to expose a Scriptnode parameter/attribute to do this? If yes, what’s the recommended setup for selecting the slot index?

If direct slot selection isn’t possible, what’s the best-practice workaround (without instantiating multiple convolution nodes)?

Screenshot attached.

Thanks!

@d-healey I just delete the script node and I can see now works , but I will made more test on diferents Daw-s and I will be back with more info , tank you a lot , you save me

@d-healey I didn’t try this …. just now I will try and come back with news , thanks a lot
