Help with loading 4x file_players from Ui button/Knob

@Rognvald the same idea as here should work I think

https://forum.hise.audio/topic/12889/fill-all-audio-loop-players?_=1757391041558

@d-healey This is great for setting one sample to all players.
I am looking for separate controls to swap samples in a folder for each file_player in Scriptnode.
I can only get it functioning with one file_player, as I dont know how to reference the other 3 file_players in the Script FX1..

Thanks for your time*

@Rognvald

const slot = ScriptFX1.getAudioFile(0);

The number you pass in here 0 is for the first slot, 1 is for the second, etc.

Brongled

@d-healey Ahh ok I was trying this before.. let me give it another go.

I am using the demo snippet code for the buttons to swap samples.

const var ScriptFX1 = Synth.getAudioSampleProcessor("Script FX1");
const slot = ScriptFX1.getAudioFile(0);



// Load Audiofiles into pool ----------------------------------------------------------------------------------------------
Engine.loadAudioFilesIntoPool();
//--------------------------------------------------------------------------------------------------------



// const vars----------------------------------------------------------------------------------------------
//const var AudioLoopPlayer1 = Synth.getChildSynth("Audio Loop Player1");
const var Random = Content.getComponent("Random1");
const var KnS1 = Content.getComponent("KnS1");
const var Next = Content.getComponent("Next1");
const var Prev = Content.getComponent("Prev1");
//--------------------------------------------------------------------------------------------------------

// Array Samples in AudioFiles-Folder----------------------------------------------------------------------
const var inst = ["Wi_Kick-1.wav","Wi_Kick-2.wav","Wi_Kick-3.wav","Wi_Kick-4.wav","Wi_Kick-5.wav","Wi_Kick-6.wav"];
//--------------------------------------------------------------------------------------------------------



//Knob1 Sample selection---------------------------------------------------------------------------------
inline function onKnS1Control(component, value)
{
    Synth.getAudioSampleProcessor("Script FX1").setFile("{PROJECT_FOLDER}"+inst[value]);
};
Content.getComponent("KnS1").setControlCallback(onKnS1Control);
//--------------------------------------------------------------------------------------------------------

// Random Button------------------------------------------------------------------------------------------
Random.setControlCallback(onRandom_Control);

inline function onRandom_Control(component, value)
{    
    if (value)
    {
        KnS1.setValue((Math.randInt(0, 5)));
        KnS1.changed();
    }
};
//--------------------------------------------------------------------------------------------------------



// Prev-Button----------------------------------------------------------------------------------------------
inline function onPrevControl(component, value)
{
    if (value)
    {
        KnS1.getValue() > KnS1.get("min") ? KnS1.setValue(KnS1.getValue() - 1) : KnS1.setValue(KnS1.get("max"));
	    KnS1.changed();
    }
};
Content.getComponent("Prev1").setControlCallback(onPrevControl);
//--------------------------------------------------------------------------------------------------------



// Next-Button ----------------------------------------------------------------------------------------------
inline function onNextControl(component, value)
{
    if (value)
    {
	    KnS1.getValue() < KnS1.get("max") ? KnS1.setValue(KnS1.getValue() + 1) : KnS1.setValue(KnS1.get("min"));
	    KnS1.changed();
    }
};
Content.getComponent("Next1").setControlCallback(onNextControl);
//--------------------------------------------------------------------------------------------------------

@Rognvald said in Help with loading 4x file_players from Ui button/Knob:

You need 4 of these, one for each of your node external audio files.

Brongled

@d-healey Ok I get that part, but how to set different files for each 4 knobs through Script FX1 is where I am confused.

//Knob1 Sample selection---------------------------------------------------------------------------------
inline function onKnS1Control(component, value)
{
    Synth.getAudioSampleProcessor("Script FX1").setFile("{PROJECT_FOLDER}"+inst[value]);
};
Content.getComponent("KnS1").setControlCallback(onKnS1Control);

David Healey

Each slot is separate.

const var ScriptFX1 = Synth.getAudioSampleProcessor("Script FX1");
const slots = [];

for (i = 0; i < 4; i++)
{
    slots[i] = ScriptFX1.getAudioFile(i);
}

Brongled

@d-healey Thats the one, is it similar for the sample array?

// Array Samples in AudioFiles-Folder----------------------------------------------------------------------
const var inst = ["Wi_Kick-1.wav","Wi_Kick-2.wav","Wi_Kick-3.wav","Wi_Kick-4.wav","Wi_Kick-5.wav","Wi_Kick-6.wav"];

@Rognvald I'm not familiar with that project

Brongled

@d-healey its the interface I am trying to link to scriptFX.
Can I reference the separate slots in the knob function?

inline function onKnS1Control(component, value)
{
    Synth.getAudioSampleProcessor("Script FX1").setFile("{PROJECT_FOLDER}"+inst[value]);
};
Content.getComponent("KnS1").setControlCallback(onKnS1Control);

You create the references in on init using the code I posted above.

You can use these within the callback.

slot[0].setFile()...
slot[1].setFile()...
etc.

Brongled

@d-healey said in Help with loading 4x file_players from Ui button/Knob:

slot[0].

I added the references and added slot function here* and getting error "Unknown function 'setFile'

inline function onKnS1Control(component, value)
{
    Synth.getAudioSampleProcessor("Script FX1").slot[0].setFile("{PROJECT_FOLDER}"+inst[value]);
};
Content.getComponent("KnS1").setControlCallback(onKnS1Control);

David Healey

@Rognvald You already have the references in on init you don't need to get the reference in the control callback - in fact you should never create references in control callbacks.

// This goes in on init
const var ScriptFX1 = Synth.getAudioSampleProcessor("Script FX1");
const slots = [];

for (i = 0; i < 4; i++)
{
    slots[i] = ScriptFX1.getAudioFile(i);
}

// This goes in the control callback
slot[0].setFile()

@d-healey Thanks again, this is where I was going wrong. Learning slowly but surly :)

Brongled

@d-healey Sorry i am still battling with this same error "Unknown function 'setFile'..

const var ScriptFX1 = Synth.getAudioSampleProcessor("Script FX1");
const slots = [];

@Rognvald Have you created external audio slots for your script effect node?

Brongled

@d-healey Yes as in the image I posted

same for all 4

@Rognvald

Shouldn't ScriptFX1 module be a part of your button script? I think you're writing to slot[i] but thats not a module. It looks like you're assigning to a slot....but it doesn't know what that slot is for.

David Healey

@Rognvald send me a snippet, I'll take a look in the morning. It's some issue with the references

Brongled

@d-healey The buttons are linked to the knobs which should change the files in the slot. I thought..
Thanks I will create a snippet :)
