Viewport

[d.healey]

Probably not a good idea to call your sampler variable Sampler, as that is a class used by HISE.

keyArray.join("\n")); will never work, you have too many closed parenthesis.

Edit: I just realised you copied that from a larger function call, so it will be fine.

@d-healey this was taken from @Christoph-Hart example codeabove mar 19

const var s = Synth.getSampler("MySampler");
const var list = Sampler.getSampleMapList();
const var Viewport1 = Content.getComponent("Viewport1");
Viewport1.set("useList", true);
Viewport1.set("items", list.join("\n"));

inline function loadSampleFromViewport(component, value)
{
    s.loadSampleMap(list[value]);
}

Viewport1.setControlCallback(loadSampleFromViewport);

[d.healey]

@mwplugs Oh I see now.

Do you have a sampler called MySampler and a viewport called Viewport1 in your project? And does you project contain at least 1 sample map?

[mwplugs]

@d-healey there are 18 as of now and yes there are Viewport1 and i just changed the sampler to Voice1

changed code to match

Content.makeFrontInterface(1024, 768);

const var Voice1 = Synth.getSampler("Voice1");
const var list = Voice1.getSampleMapList();
const var Viewport1 = Content.getComponent("Viewport1");
Viewport1.set("useList", true);
Viewport1.set("items", list.join("\n"));
const var Viewport2 = Content.getComponent("Viewport2");
Viewport2.set("useList", true);
Viewport2.set("items", keyArray.join("\n"));

inline function loadSampleFromViewport(component, value)
{
    Voice1.loadSampleMap(list[value]);
}

Viewport1.setControlCallback(loadSampleFromViewport);

inline function createTwoLevelHierarchy()
{
    local allList = Voice1.getSampleMapList();
    local obj = {};
    
    for(id in allList)
    {
        local tokens = id.split("/");
        local key = tokens[0];
        local value = tokens[1];
        
        if(obj[key])
            obj[key].push(value);
        else
            obj[key] = [value];
    }
    
    return obj;
}

const var sorted = createTwoLevelHierarchy();

const var obj = {}; // some object

const var keyArray = [];

for(k in obj)
    keyArray.push(k);

[mwplugs]

we are attempting to take categories (subfolders) of samplemaps on left veiwport (viewport2) and the right viewport (viewport1) display the samplemaps in that category and make them loadable.

the sorted object is throwing out the right data in the watcher

{
  "Brass": [
    "FreshHornStaccato"
  ],
  "Guitar": [
    "AcousticCampfire"
  ],
  "Keys": [
    "DeepFuzzVibe",
    "HorrorPianoFuzz"
  ],
  "Piano": [
    "CloudyJazzPno",
    "GoldenPiano",
    "RustyPiano"
  ],
  "Strings": [
    "ChamberTremelo",
    "ChamberViolinPizz",
    "ChamberViolinSpiccati",
    "ChamberViolinTremble",
    "MidMedSoloString",
    "MovieStringStacc",
    "SoloViolinLeg",
    "ViolinPizz1",
    "ViolinStaccato",
    "ViolinStaccatoB"
  ],
  "Vox": [
    "WhooMaleVox"
  ]
}

however the keyArray is simply spitting out []

[d.healey]

Try this

Oh, there's your problem

const var obj = {}; // some object

const var keyArray = [];

for(k in obj)
    keyArray.push(k);

You are declaring an empty object which you are using in the for loop. So the output will be empty.

[mwplugs]

@d-healey im assuming its supposed to be pulling from the sorted object. so do i replace the word object with sorted?

[d.healey]

Yeah, if that's what you want it to do. And you can delete the other keyarray stuff.

[mwplugs]

ok now the keyArray has the categories. but when i changed the line:

Viewport2.set("items", list.join("\n"));

to

Viewport2.set("items", keyArray.join("\n"));

it says
Line 10, column 37: Unknown function 'join'

like usual

[d.healey]

@mwplugs What does keyArray contain?

[mwplugs]

@d-healey ```
[
"Brass",
"Guitar",
"Keys",
"Piano",
"Strings",
"Vox"
]

[mwplugs]

@mwplugs as desired it shows the categories

[d.healey]

But what does it contain at the point you are calling the join function.

[mwplugs]

@d-healey im simply trying to get the viewport to use the keyArray list.

the only implementation ive seen that works to use lists is

Viewport1.set("useList", true);
Viewport1.set("items", list.join("\n"));

[mwplugs]

without join it displays all on one line/selection basically as one long word

[d.healey]

The program runs from top to bottom, so if you do something with keyArray near the top of your script, before keyArray is populated, you won't get any useful results. You need to make sure things happen in the correct order.

[mwplugs]

@d-healey there we go! ok so i got the left to populate with categories by rearranging.

now how do i get the samplemaps on the right to correspond to the category selected on the left?

[mwplugs]

im guessing i will have to have another list being made based on the selection somehow
