Sample switching with presets in Audio Loop Player

callybeat

Hello how are you!

I have been reading this forum for some months and it is a great knowledge niche about Hise in fact looking for I found all the answers to my doubts, but at this point I am somewhat lost ..,

It turns out that I want to use an Audio Loop Player to mix with a Waveform generator and thus create different presets, I already tried to do it with a combo box through sample maps, in fact I can select sample maps very well in combo box but it does not load them in Audio Loop Player and the console sends me errors that I do not understand

I annex the lines that I wrote in case someone can give me some advice :)

Thanks in advance!

//Audio Loop Player
const var Sampler = Synth.getChildSynth("Sampler");

//Sample maps array
const var sampleMaps = Sampler.getSampleMapList();

//Combo box
const var cmbSampleMaps = Content.getComponent("cmbSampleMaps");
cmbSampleMaps.set("items", sampleMaps.join("\n"));

inline function oncmbSampleMapsControl(component, value)
{
	Console.print(value);
    Sampler.asSampler().loadSampleMap(sampleMpas[value-1]);
};

Content.getComponent("cmbSampleMaps").setControlCallback(oncmbSampleMapsControl);

This is the error that the console throws me :{ ??? I think it's in Chinese heheh :)

Interface:! function not found {SW50ZXJmYWNlfHwxMjI5fDUyfDQ4}
: onInit() - Line 52, column 48 {SW50ZXJmYWNlfHwxMjI5fDUyfDQ4}

Greetings and success!

@callybeat there is a misspelling here:

Sampler.asSampler().loadSampleMap(sampleMpas[value-1]);

@ulrik Thank you very much friend! :)

You know I already corrected the spelling mistake but it still did not work, in fact I noticed that Sample maps in the name of the folder is written with capital letters and I thought about changing that in the references but in the same way it did not work :( .. it still sends me the same error the console

//Audio Loop Player
const var Sampler = Synth.getChildSynth("Sampler");

//Sample maps array
const var SampleMaps = Sampler.getSampleMapList();

//Combo box
const var cmbSampleMaps = Content.getComponent("cmbSampleMaps");
cmbSampleMaps.set("items", SampleMaps.join("\n"));

inline function oncmbSampleMapsControl(component, value)
{
	Console.print(value);
    Sampler.asSampler().loadSampleMap(SampleMaps[value-1]);
};

Content.getComponent("cmbSampleMaps").setControlCallback(oncmbSampleMapsControl);

Interface:! function not found {SW50ZXJmYWNlfHwxMjI5fDUyfDQ4}
: onInit() - Line 52, column 48 {SW50ZXJmYWNlfHwxMjI5fDUyfDQ4}

@callybeat you made a reference to the Sampler using the "Create generic script reference" so the

const var SampleMaps = Sampler.getSampleMapList();

throws an error saying "function not found"
So if you instead make a "Create typed Sampler script reference" this function exist and can be used.

And when you have this reference to the Sampler you have to use

Sampler.loadSampleMap(SampleMaps[value-1]);

instead of

Sampler.asSampler().loadSampleMap(SampleMaps[value-1]);

Here's the changed code

//Audio Loop Player
const var Sampler = Synth.getSampler("Sampler");
//Sample maps array
const var SampleMaps = Sampler.getSampleMapList();

//Combo box
const var cmbSampleMaps = Content.getComponent("cmbSampleMaps");
cmbSampleMaps.set("items", SampleMaps.join("\n"));

inline function oncmbSampleMapsControl(component, value)
{
	Console.print(value);
    Sampler.loadSampleMap(SampleMaps[value-1]);
};

Content.getComponent("cmbSampleMaps").setControlCallback(oncmbSampleMapsControl);

@ulrik Friend thank you very much!

You are right the reference changes totally when selecting "Create typed Sampler script reference" although I see that it changes a bit since it is an Audio Loop Player

this looks much better

const var Sampler = Synth.getAudioSampleProcessor("Sampler");

that this old reference

const var Sampler = Synth.getChildSynth("Sampler");

I also change the custom logic
this

Sampler.asSampler().loadSampleMap(SampleMaps[value-1]);

to this

Sampler.loadSampleMap(SampleMaps[value-1]);

and the result is this code

//Audio Loop Player
const var Sampler = Synth.getAudioSampleProcessor("Sampler");

//Sample maps array
const var SampleMaps = Sampler.getSampleMapList();

//Combo box
const var cmbSampleMaps = Content.getComponent("cmbSampleMaps");
cmbSampleMaps.set("items", SampleMaps.join("\n"));

inline function oncmbSampleMapsControl(component, value)
{
	    Sampler.loadSampleMap(SampleMaps[value-1]);
};

Content.getComponent("cmbSampleMaps").setControlCallback(oncmbSampleMapsControl);

But I think luck is not with me since the console sends me an error :) I think it is known that I am a beginner and it does not stop welcoming me lol

Interface:! function not found {SW50ZXJmYWNlfHwxMjM5fDUyfDQ4}
: onInit() - Line 52, column 48 {SW50ZXJmYWNlfHwxMjM5fDUyfDQ4}

The only thing I'm sure of is that I'm doing something wrong lol

ulrik

@callybeat Aha, ok so your reference to "Sampler" is not a reference to a sampler actually, cause it's an "Audio Loop Player", then I understand why it's not working.
You can not get a sampleMap list from an Audio Loop Player because it's not a sampler :)
So this line is not working:

const var SampleMaps = Sampler.getSampleMapList();

because an ALP doesn't have a sample map.

Can you describe what you want to do?

Never mind, I see you want to load samples into the ALP using a combobox, right?

ulrik

@ulrik I think you need to use this

Engine.loadAudioFilesIntoPool();
Sampler.setFile(String fileName)

to load the audio file into the ALP
so I would do something like this:

store the audio files names in an array

audioFiles = ["audio1.wav", "audio2.wav", "audio3.wav"];

and point to this array in the cmb

Do you have an example snippet for this?
I am missing the connection here

ulrik

@MikeB sorry, no snippet here, just looking at the documentation
https://docs.hise.audio/scripting/scripting-api/audiosampleprocessor/index.html

callybeat

@ulrik a thousand thanks for the support thanks to you and @MikeB for the help, I think that with the example mikeB shared I almost finished my first project in Hise, thank you both are very helpful

ulrik

@callybeat I'm glad it worked out allright for you!

I thought I would paste the solution of the theme here in case someone needs it ..
