@iamlamprey so can you post the code that works?

err that points me further up this thread at a post that says its not working...

d.healey

@Lindon Yup, didn't do what I thought it did. Scroll up until you find my post with a link to a demo project, wasn't that far back.

@Christoph-Hart We need a way to accurately link to other posts in a thread, clicking the timestamp appears not to work.

OK thanks.

@Lindon Here's where I'm at so far, note that it's still very much a WIP (loaded expansions aren't persistent in a DAW yet, for example)

/*Basic Player plugin with on-the-fly sample-loading and image-changing + hiding of GUI elements.

I've also hidden the init sample locate dialog with:

HISE_SAMPLE_DIALOG_SHOW_INSTALL_BUTTON=0
HISE_SAMPLE_DIALOG_SHOW_LOCATE_BUTTON=0

In the Extra Definitions [Your OS] Preferences
*/
const var expHandler = Engine.createExpansionHandler();
const var SamplerRR = Synth.getChildSynth("SamplerRR");
var currentExpansion = "";

expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                     expHandler.Intermediate, 
                                     expHandler.Encrypted]);

var expansionDirectory = FileSystem.getFolder(FileSystem.Samples); //Changes using the Custom Setting FloatingTile
reg hr;

const var Image_BG = Content.getComponent("Image_BG");

//Set Sample Folder Button (Just shows a panel, which contains the CustomSettings FloatingTile)

inline function onButton1Control(component, value)
{
    Panel_ChangeSampleFolder.showControl(value);
};

Content.getComponent("Button1").setControlCallback(onButton1Control);

//Install Library Button

inline function onButton2Control(component, value)
{
    if (value)
    {    
        FileSystem.browse(expansionDirectory, false, "", function(result) 
    {
        hr = result;
        expHandler.installExpansionFromPackage(hr,FileSystem.getFolder(FileSystem.Samples));
        expHandler.refreshExpansions(); 
    });
    };
};

Content.getComponent("Button2").setControlCallback(onButton2Control);

//Library Select (Like Kontakt's Browser)

//Bloom

inline function onExpansions_ButtonBloomControl(component, value)
{
    Engine.setCurrentExpansion("Bloom");
    currentExpansion = "Bloom"; //This is used in other functions elsewhere.
    //Put Stuff Under This

    //Setting Background Image
    backgroundImage = ("{EXP::Bloom}bg_bloom.png");
    Image_BG.setAlpha(1);
    Image_BG.set("fileName", backgroundImage);  

    //Hiding/Showing UI Elements for Specific Libraries
    ComboBox_Atlas.set("visible", 0);

    //Setting up different Samplers
    SamplerRR.setAttribute(12, 0);

    SamplerRR.asSampler().loadSampleMap("{EXP::Bloom}Bloom_SampleMap");
};

@iamlamprey - thanks - looks not "too" complex...

How would I make the loaded expansion re-load on DAW close/reopen?

Making currentExpansion a const var obviously breaks the button functions that change it, and it doesn't default to a string unless I give it an initial value of "", which means calling that won't load the right expansion..

d.healey

@iamlamprey Expansions are automatically loaded when one of the expansion's presets is used, so as long as the DAW is saved and closed after a preset has been selected it "should" be there when you reopen the DAW.

A Former User

@d-healey Guess it's time to add a preset system then...

A Former User

Unrelated but has anyone else had the Custom Keyboard FloatingTile randomly play a high F and stick when clicking GUI elements?

I thought was my old midi controller but it only happens when I click something on the GUI, both in HISE and in DAW.

Super weird

I still need help regarding making expansions persistent and loading on DAW open/close.

(streamable.com)

I can install the libraries and load them manually just fine. But on DAW save/load it defaults back to no expansion HOWEVER if I hit "Open Preset Folder" in the preset browser, it directs me to the right expansion folder.

So somehow the currentExpansion is saved, but I can't figure out how to restore it.

I've tried making init presets and using

Engine.loadNextUserPreset(1);

in both button callbacks and onInit, without any success.

//init stuff:

include("CustomExpansionLoading.js");

const var expHandler = Engine.createExpansionHandler();
var currentExpansion;

//Load expansions

switch (currentExpansion)
{
    case "Cloudburst":
        loadCloudburst();
        break;
        
    case "Atlas":
        loadAtlas();
        break;
        
    case "Blackout":
        loadBlackout();
        break;
        
    case "Bloom":
        loadBloom();
        break;
    
    default:
};

inline function loadBloom()
{
        //Initialize Expansion    
    Engine.setCurrentExpansion("Bloom");
    currentExpansion = "Bloom";
        //Put Stuff Under This
        //Setting BG Image        
    backgroundImage = ("{EXP::Bloom}bg_bloom.png");
    Image_BG.setAlpha(1);
    Image_BG.set("fileName", backgroundImage); 
        //Setting up Samplers    
    SamplerRR.setAttribute(12, 0);
    Sampler_NoRR.setAttribute(12, 1);
    Sampler_Loops.setAttribute(12, 1);
    SamplerRR.setBypassed(0);
    Sampler_NoRR.setBypassed(1);  
    Sampler_Loops.setBypassed(1);
    SamplerRR.asSampler().loadSampleMap("{EXP::Bloom}Bloom_SampleMap");   
        //Setting Key Colours    
    colourKeysReset();
    colourKeysBloom();
        //Hiding othe GUI Elements    
    ComboBox_Atlas.set("visible", 0);    
    Button_LoopSpeedHalf.showControl(0);
    Button_LoopSpeedDouble.showControl(0);
    Label_LoopSpeedHalf.showControl(0);
    Label_LoopSpeedDouble.showControl(0);     
};

//Button to switch to this expansion.
inline function onExpansions_ButtonBloomControl(component, value)
{
    if (value)
    {
        loadBloom();
    }
};

A lot of it is dependant on the variable currentExpansion, and I think somehow it isn't saving that right.

I've probably massively overcomplicated this...

A Former User

I've just realized there's a

Engine.setCurrentExpansion and a expHandler.setCurrentExpansion.

This might be the cause of my woes...

A Former User

OKAY got it working (I think), I didn't know about the expHandler.setExpansionCallBack() function and was trying to do things manually this whole time

arminh

@iamlamprey hey, how did you get image covers from every expansion?

d.healey

@arminh Each expansion has an images folder, put your image in there.

arminh

@d-healey i made it, but even if i have image in Images folder i have error

Interface:! Image {EXP::Factory}exp_cover.png not found

d.healey

@arminh I would assume this is necessary

arminh

@d-healey oh i tried create this by painroutines but as i can see we can't just put image path?

Here's example

g.drawImage(expansionsArr[i].cover, [50,50,50,50], 0, 0);

d.healey

You need to load the image into the panel first with the loadImage command.
