depending on what your end goal is

I just want a expansion system in place... I like how the one from the demo is set up, But all I need is...

A button which when clicked will load the expansion
And a way to cypher through the samplemaps (combobox maybe)?

Seems simple but I cant for the life of me figure it out lol :sad_but_relieved_face: :crying_face:

Why not use the preset browser to load the expansions? That eliminates the need to add a button per expansion.

And a way to cypher through the samplemaps (combobox maybe)?

This part is easy. I'll make a snippet for you.

thank you, I can script it for the factory samplemaps just not for the expansions.

A lot has changed in the last year since Christoph made that tutorial.

humm the combobox isn't loading anything, but its a good starting point for me.

It doesn't load anything until you load an expansion.

BWSounds

@d-healey
Yep yep, thanks man I appreciate it.

BWSounds

@bwsounds
ok, last question, so from my understanding you cant replace the EXP:... part of the expansion name but you can "split" it?

I see this in the docs..

split
Splits the string into an array with the given separator.
String.split(var separatorString)

But I also read in a post that that you could use substring as well...

What is the best way to go about doing this while using comboboxes?

d.healey

@bwsounds Why not use .replace()?

BWSounds

@d-healey
if im not mistaken, I think I read in a post where you said it wouldn't work. I may have read incorrectly.

d.healey

@bwsounds Explain the context and I'll provide a solution, I'm not 100% sure what you want to do.

DanH

@bwsounds this is what I do:

for (i = 0; i < sampleMapsed.length; i++)
        {
        sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
        sampleMapsed[i] = sampleMapsed[i].replace("}");
        sampleMapsed[i] = sampleMapsed[i].replace(expName);

        }

ok, so far I have this, which loads the samplemaps into a combobox(list1)...

It works great, but the {EXP:..} text which is included with the samplemap text is a bit unappealing.

So what I want to do is remove it {EXP:..} , but im lost on how...

const var expHandler = Engine.createExpansionHandler();
const var expansions = expHandler.getExpansionList();
expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                     expHandler.Intermediate, 
                                     expHandler.Encrypted]);
const var expansionNames = [];


for(e in expHandler.getExpansionList())
    expansionNames.push(e.getProperties().Name);


const   Sampler1 = Synth.getSampler("Sampler1");
 const list1 = Content.getComponent("list1");
 list1.setControlCallback(onlist1Control);
 const var namesExp = [];
 
 
inline function onlist1Control(component, value)
{
	if (value > 0)
	{
		local sampleMap = component.getItemText();
         


		if (sampleMap != "")
			Sampler1.loadSampleMap(sampleMap);	
		{	
			
			namesExp.clear();
		    var smname = expSampleMaps[value];
			
				
			for (e in smname)
		    e.replace("{EXP::" + getExpansionName() + "}", ""); 
		    list1.set("items", smname.join("\n"));
			
 
    }			
  }		
}


expHandler.setExpansionCallback(function(e)
{
	list1.set("items", e.getSampleMapList().join("\n"));
});

no iterable type keeps popping up, so I know im way off. Did a search on it but nothing came up.

humm.. I tried something like that but the sampler didn't recognize the samplemaps..
I look into it again

@bwsounds I excecute this in an expansionSelector callback - which in my case is a combobox. How are you selecting and switching between expansions? And do you have 'factory' presets as well?

If what you want is similar to mine I can send over my code when back at my machine tomorrow

BWSounds

@danh
That would be great!
And no factory presest, I was planning on having an expansion titled "FACTORY"
also Im using the preset browser to switch between expansions.

This video was made for you

And you should read this - https://docs.hise.audio/scripting/scripting-in-hise/hise-script-coding-standards.html

@bwsounds here it is, essentially it's all dealt with with the 'expHandler.setExpansionCallback' function. 'SAMPLEBOX' is my combo box which lists the available sample maps for the user to browse, and the 'sampleMapsed' array is the list of expansion sample maps (so I guess you can ignore the 'sampleMaps' array). It also removes all the Expansion text so you just get the name of your sample map in the combo box.

const var expHandler = Engine.createExpansionHandler();

const var expansions = expHandler.getExpansionList();

expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                     expHandler.Intermediate, 
                                     expHandler.Encrypted]);
                                     
const var expansionNames = [];
/// Push 'FACTORY" into the available expansion packs list so users can navigate back to factory presets

expansionNames.push("FACTORY");

for(e in expHandler.getExpansionList())
    expansionNames.push(e.getProperties().Name);
    
const var ExpansionSelector = Content.getComponent("ExpansionSelector");
ExpansionSelector.set("items", expansionNames.join("\n"));

// Implement the expansion switch

inline function onExpansionSelectorControl(component, value)
{
	local expansionToLoad = component.getItemText();
	
	// We want the first item to reset the current expansion
	// so we need to change it to an empty string
	if(expansionToLoad == expansionNames[0])
        expansionToLoad = "";
    
	expHandler.setCurrentExpansion(expansionToLoad);
};

Content.getComponent("ExpansionSelector").setControlCallback(onExpansionSelectorControl);

var sampleMaps = Sampler.getSampleMapList();
var sampleMapsed = Sampler.getSampleMapList();

inline function newcombobox(newExpansion)
{

       if(isDefined(newExpansion))

    {
        local cx = expHandler.getCurrentExpansion();
        sampleMaps = cx.getSampleMapList();
        sampleMapsed = cx.getSampleMapList();
        local expansionProps = cx.getProperties();
        local expName = expansionProps.Name;

        for (i = 0; i < sampleMapsed.length; i++)
        {
        sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
        sampleMapsed[i] = sampleMapsed[i].replace("}");
        sampleMapsed[i] = sampleMapsed[i].replace(expName);

        }

        SAMPLEBOX.set("items", "");
        SAMPLEBOX.set("items", sampleMapsed.join("\n"));
       
    }
    else
    {
        sampleMaps = Sampler.getSampleMapList();
        SAMPLEBOX.set("items", "");
        SAMPLEBOX.set("items", mySampleMapNames.join("\n"));

    }

}

expHandler.setExpansionCallback(newcombobox);

newcombobox(undefined);

Thank you!
But im still having the same issue... when I do this

     //   sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
     //   sampleMapsed[i] = sampleMapsed[i].replace("}");
     //   sampleMapsed[i] = sampleMapsed[i].replace(expName);

the samplemaps load up, but if I remove the

//

the samplemaps load up.... i'll dig around and mess with this a bit, maybe im missing something... thank you.

BWSounds

@danh
ok, after a few days I figured it mostly out, thank you.
one issue still remains... once I switch back to "factory" my combobox doesn't populate those samplemaps... What could cause that?
