Unknown Functions 'set' & 'getRange'

[trillbilly]

Hey Gang,

Im using a version of the Custom Sample Import. Everything was working great until I opened my project tonight and all the Samplers 'sound.set' and 'sound.getRange' all throw an UKNOWN FUNCTION error. It seems these are both for the Loop Range & Loop Xfade.

If I open any presets with the Loop Range or Loop Xfade saved within a preset, HISE crashes.

What are best practices for figuring out the issue? Has anyone had something like this happen before?

@trillbilly show us the code....

[trillbilly]

@Lindon Yes, of course. Here is Sampler 1. Its in the onLoopControl & onXfadeControl Functions.

I have ran my projects XMLBackup through an XML Validator and it returned no issues. I have also removed all other coding/functions to see if something was interfering, but, it still didnt work. I also went back through and checked that I had the correct included scripts and that they were up to date.

It kind of seemed out of nowhere (of course it was, I wasnt expecting it).

//SAMPLER 1
const var Sampler1 = Synth.getSampler("Sampler1");
reg sound;
reg totalSamples = 0;
reg isCustomMap = false;


//! "Page" Logic
// Nothing special, it just shows / hides certain elements...

const var editButtons = [Content.getComponent("EditLoop"),
                         Content.getComponent("EditRange"),
                         Content.getComponent("ShowDropper")];

const var EDIT_LOOP = 0;
const var EDIT_RANGE = 1;
const var SHOW_DROPPER = 2;

const var AudioWaveform1 = Content.getComponent("AudioWaveform1");
const var SampleDropper = Content.getComponent("SampleDropper");
const var LoopPanel = Content.getComponent("LoopPanel");
const var Reverse = Content.getComponent("Reverse");



inline function setEditMode(editMode)
{
	AudioWaveform1.set("enableRange", editMode == EDIT_RANGE);
	LoopPanel.set("visible", editMode == EDIT_LOOP);
	SampleDropper.set("visible", editMode == SHOW_DROPPER);
}

inline function setEditModeCallback(component, value)
{
	if(value)
		setEditMode(editButtons.indexOf(component));
}

for(b in editButtons)
	b.setControlCallback(setEditModeCallback);


inline function onSampleMapLoaderControl(component, value)
{
	if(value > 0)
	{
		local id = Sampler1.getSampleMapList()[value - 1];
		Sampler1.loadSampleMap(id);
	}
};

Content.getComponent("SampleMapLoader").setControlCallback(onSampleMapLoaderControl);

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

SampleMapLoader.set("items", Sampler1.getSampleMapList().join("\n"));


setEditMode(EDIT_RANGE);

//! Non persistent UI elements
//  These UI controls do not store any data, but will read / write
//  to the sample map directly.


inline function onLoopControl(component, value)
{
	sound.set(Sampler1.LoopEnabled, value);
	
	// Make sure the loop end is set to the sample end when you
	// enable the loop the first time
	if(sound.get(Sampler1.LoopEnd) == 0)
		sound.set(Sampler1.LoopEnd, sound.getRange(Sampler1.LoopEnd)[1]);
	
	// update the loop point panel
	LoopPointDragger.updateLoopPoints();
	
	// write the loop points back into the base64 string
	SampleLoadSave.storeSampleMapData();
};

Content.getComponent("Loop").setControlCallback(onLoopControl);

inline function onXFadeControl(component, value)
{
	// the slider is 0...1 so we can use the available crossfade range length
	// to figure out how big of a crossfade we want
	local newValue = parseInt(sound.getRange(Sampler1.LoopXFade)[1] * value);
	sound.set(Sampler1.LoopXFade, newValue);
	
	LoopPointDragger.updateLoopPoints();
	SampleLoadSave.storeSampleMapData();
};

Content.getComponent("XFade").setControlCallback(onXFadeControl);

@trillbilly An unknown function error means the thing on the left side of the . does not have the function you are trying to call.

This could be because you've used the wrong variable type or because it's undefined.

[trillbilly]

@d-healey Ahhh ok. So now I need to figure out what was changed, and how, because those functions were working just hours earlier.

[d.healey]

@trillbilly Is it because the sample map is not loaded?

[trillbilly]

@d-healey You're right, when I load an internal sample map, it works. But it wont work anymore with Drag-And-Drop samples.

I would rather use the sample maps from internal samples, but, you cant edit the loop range. I've made a post about it HERE.

Also, obiviously Im using custom sample import so users can use their own samples. Im confused why it doesnt recognize them as sample maps anymore?

[trillbilly]

@d-healey Ok, scratch that. its working ONLY if there is a sample loaded. If the sampler is cleared, it throws the error.

If you save a preset without a sample/samplemap loaded, it will save but crash upon opening it again.

[d.healey]

@trillbilly So before you try to call a function on the sound object you need to check if the object is populated.

if (!isDefined(sound))
    return;

[trillbilly]

@d-healey That will work better than my idea of populating an empty samplemap when a sampler is not in use. Thank you.

[trillbilly]

@d-healey It solved the sound.set issue but not the sound.getRange issue.

[d.healey]

@trillbilly This line?

local newValue = parseInt(sound.getRange(Sampler1.LoopXFade)[1] * value);

[trillbilly]

@d-healey Yes, that is correct

[d.healey]

@trillbilly And you tried placing the check before it?

[trillbilly]

@d-healey No, Im an idiot, I only put it in 1 callback.
Worked like a charm. Much appreciated.
