How do You Load an Audio File into a ScriptNode Convolution Reverb?

[clevername27]

I've seen this thread - could somebody please break this down? As I understand…

---

1. Create an external audio slot in the uncompiled ScriptNode synth.

2. Compile the ScriptNode synth, and add it to a Silent Synth, inside a Hard-Coded Polyphonic module.

---

3. Create an AudioSample

const scriptNodeSynth = Synth.getAudioSampleProcessor("fx_MODEL_SynthesiserNode");

Here I break down…I don't seem to have the syntax correct.

---

4. Create a Reference to the Slot

var impulseResponse = scriptNodeSynth.getAudioFile(1);

---

5. Load an Audio File

Lost here. AudioSampleProcessor has a setFile method, but I'm not sure if that's applicable here (and if so, how to use it). As I understand it, getAudioFile returns a ScriptAudioWaveform. But I don't want to present a user interface to the ScriptNode—I just want to load a file.

6. Relax with Tasty Beverage of Choice

I'm actually good on this one.

Please help?

@clevername27 You're good up to 4.

You don't need this:

impulseResponse = scriptNodeSynth.getAudioFile(1);

simply do this:

// this is the reference to the audio slot
const scriptNodeSynth = Synth.getAudioSampleProcessor("fx_MODEL_SynthesiserNode");

scriptNodeSynth.setFile(the_relative_path_to_your_reverb_file);

You can call this function in a CB obviously.

6. A glass of red wine for me please :)

@Matt_SF Thanks for look at my question - I'm really stumped here.

This line produces an error (see the screenshots in my original question).

~~const scriptNodeSynth = Synth.getAudioSampleProcessor("fx_MODEL_SynthesiserNode");~~

Got it. Thanks again.

@clevername27 Aaaah I overlooked #2.

You have to use the filters.convolution node, not the core.file_player.

@Matt_SF Cheers mate!
