@d-healey yes, that's what was missing.

Thanks so much!

Great, thanks a lot, guys!

@d-healey yes, that's what was missing.

Thanks so much!

@d-healey not sure where to find this. In HISE settings I couldn't find anything related to that

@d-healey yes, from the repo I've cloned. I've just cloned and built it again, but it's getting the same error. The wizard doesn't download anything. I can't click next, as a get that strange error, like if I had to click the red checkbox, but it's not clickable.

@d-healey maybe there's a more stable commit I could try?

I have built HISE using the instructions in the repo. I have two macs, in one it's working fine, on the other I did the same thing, but am getting this error message:

"The source code has a different commit hash than the HISE build. This will likely lead to undefined behaviour including compile errors or undetected errors. In order to proceed with the compilation, type 'I know' and click OK"

My PATH has the correct path to HISE, which is the same that I've built from.

The wizard says the path is correct:

This step is incorrect, though:

But when I click "Next" it gives this error. There's no place I can click to fix it:

What else should I do besides building HISE from the source code?
Is there a recommended commit?

@d-healey great, thanks!

Newbie question: I have these six samples, with 2 velocities. However, the sound doesn't respond to the velocity, it has the same volume for the first dynamic, then the same volume for the second one, regardless of the velocity.

Am I doing something wrong? Is there a place I can activate it?

@daniloprates great, thanks David!

Hey guys, noob question, but I just can't seem to find the Routing Matrix icon.

Is there any extra component that I should add in order to enable it?

Yes, this was done by ChatGPT I tried to reply the post with this warning, but I didn't have the rights, as a new user.

Thanks David!

setControlCallback() - "Control Callback function must be an inline function" Error

Problem

I'm developing a custom knob UI in HISE that draws a blob shape.
I want to click a button to regenerate the blob (change its randomness),
but I keep getting this error:

Control Callback function must be an inline function

I've tried:

• Making sure the function inside setControlCallback() is completely inline
• Avoiding external global variables inside setControlCallback()
• Using setAttribute() to store and retrieve blob data within the knob component
• Calling Content.repaint(); after updating values

None of these approaches work. The error persists.

What I'm Trying to Achieve

1. I have a custom knob UI that draws a blob shape.
2. I want to click a button to regenerate the blob shape (change its randomness).
3. The knob should NOT update the blob shape—only the button should trigger the change.

What’s Failing

Even when using a fully inline function like this:

btn.setControlCallback(function(component, value) {
    if (value) {
        Console.print("Blob Clicked! Generating new shape.");
        
        // Try storing data inside the knob to update later
        var knobComponent = Content.getComponent("knob1");
        knobComponent.setAttribute("blobData", generateBlob(9, 0.35, 0.1));

        Content.repaint(); // UI refresh
    }
});

I still get the error.

Questions for the Community

1. What EXACTLY does HISE require to make an inline function "valid" inside setControlCallback()?
2. What is the best way to store dynamically changing data in a knob component?
3. Is there a different approach that avoids this error entirely?

I’d appreciate any insights. Thanks!
