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 In Image Draw I have : g.drawImage(obj.text, a, 0, 0); and I just change this , for column index >= 0 .... obj.text, obj.area ( was a here) , "centred"

@filipalex96 I solve the problem with this : if (obj.columnIndex == -1)
{
g.setColour(Colours.withAlpha(Colours.white, obj.hover ? 1.0 : 0.5));
g.drawImage(obj.text, a, 0, 0);
}

else if (obj.columnIndex >= 0)
{

    g.setFont("Default", obj.selected ? 15.0 : 14.0);
   g.drawAlignedText(obj.text, obj.area, "centred");
   
   // TEXT
      var alpha = obj.selected ? 1.0 : (obj.hover ? 0.9 : 0.6);
      g.setColour(Colours.withAlpha(Colours.white, alpha));
   
      g.setFont("Default", obj.selected ? 15.0 : 14.0);
      g.drawAlignedText(obj.text, obj.area, "centred");

} Thank You for Help , have a nice day

@David-Healey Any ideas? Thanks!

@David-Healey said in PresetBrowser Expansion Icons work, but text in other columns disappears when using drawPresetBrowserListItem:

you need an else

// ICON column
if (obj.columnIndex == -1)
{
g.setColour(Colours.withAlpha(Colours.white, obj.hover ? 1.0 : 0.5));

    // draw only if obj.text matches a loaded image id
    if (lav.getImage(obj.text))
        g.drawImage(obj.text, a, 0, 0);

    return;
}
else // TEXT columns
{
    g.setColour(Colours.withAlpha(Colours.white,
        obj.selected ? 1.0 : (obj.hover ? 0.9 : 0.65)));

    g.setFont("Default", obj.selected ? 15.0 : 14.0);
    g.drawAlignedText(obj.text, a.reduced(8, 0), "left");
}

});

same behavior

@David-Healey Thanks for the clarification — that makes sense
I understand now that drawPresetBrowserListItem overrides drawing for all columns, so everything has to be drawn manually.

I tried doing exactly that, but I still get the same behavior.
When I draw both the icon column and the text columns, the text becomes visible but the expansion icon disappears.

This is the code I tried:

lav.registerFunction("drawPresetBrowserListItem", function(g, obj)
{
var a = obj.area;

// Expansion icon column
if (obj.columnIndex == -1)
{
    g.setColour(Colours.withAlpha(Colours.white, obj.hover ? 1.0 : 0.5));

    if (lav.getImage(obj.text))
        g.drawImage(obj.text, a, 0, 0);

    return;
}

// Other columns (text)
g.setColour(Colours.withAlpha(Colours.white,
    obj.selected ? 1.0 : (obj.hover ? 0.9 : 0.65)));

g.setFont("Default", obj.selected ? 15.0 : 14.0);
g.drawAlignedText(obj.text, a.reduced(8, 0), "left");

});

The result is:

Text in the other columns shows correctly

The expansion icon still does not appear

The icons are loaded like this:

inline function loadExpansionImagesIntoLaf(obj)
{
local expHandler = Engine.createExpansionHandler();

for (e in expHandler.getExpansionList())
{
    local img = e.getWildcardReference("Icon.png");

    if (isDefined(img))
        obj.loadImage(img, e.getProperties().Name);
}

}

Am I misunderstanding what obj.text contains in the icon column?
Is there a specific property in obj that should be used to identify the expansion / library for the current row, instead of obj.text?

Thanks a lot for your help!

Hi everyone,

I’m working on a custom PresetBrowser UI in HISE and I’m a bit stuck.
I feel like I’m going in circles, so I’d really appreciate some guidance from someone who knows the internals better.

What I’m doing

I enabled Expansions and I load an Icon.png from each expansion into a custom LookAndFeel.
The icon drawing itself works perfectly when I only draw the icon column.

Here is the exact code I’m using right now:

inline function loadExpansionImagesIntoLaf(obj)
{
local expHandler = Engine.createExpansionHandler();

for (e in expHandler.getExpansionList())
{
    local img = e.getWildcardReference("Icon.png");

    if (isDefined(img))
    {
        obj.loadImage(img, e.getProperties().Name);
    }
}

}

lav.registerFunction("drawPresetBrowserListItem", function(g, obj)
{
var a = obj.area;

if (obj.columnIndex == -1)
{   
    g.setColour(Colours.withAlpha(Colours.white, obj.hover ? 1.0 : 0.5));
    g.drawImage(obj.text, a, 0, 0);
}

});

The problem

With this code:

Expansion icons show correctly

Text in the other columns (preset name, tags, etc.) is not visible anymore

If I add an else branch and manually draw the text:

Text becomes visible

The expansion icon stops showing

So basically:

Icon only → icon works, text disappears

Icon + text (using else) → text works, icon disappears

@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?
