Audio Loop Player Script

[VorosMusic]

Hi all you helping people out there.
I've just started my second project in Hise and beeing more complex than the first, the first issue already appered.

I would like to have a Loop of static noise, well ... looping for lack of a different word,.
Activated with a button and NOT via midi.

Any ideas and tipps, how I could script that?
Thanks in advance!

Hmm...
I set up a Switch/Button to change a few things as well as play a note, but the note is only getting played, when compiling. Everything else seems to get correctly triggered after the callback.

inline function onSwitchControl(component, value)
{
	if(value)
	{
		Keys.set("visible", 1);
		NoiseSlide.set("visible", 1);
		KeyON.setBypassed("false");
		KeyOFF.setBypassed("false");
		Synth.playNote(6, 100);
	}
	else
	{
		Keys.set("visible", 0);
		NoiseSlide.set("visible", 0);
		KeyON.setBypassed("true");
		KeyOFF.setBypassed("true");
	}
};

Switch.setControlCallback(onSwitchControl);

...Any ideas, what I'm missing?

@VorosMusic You're passing booleans as strings.

inline function onSwitchControl(component, value)
{
	if(value)
	{
		KeyON.setBypassed(false); //No quotation marks
		KeyOFF.setBypassed(false);
		Synth.playNote(6, 100);
	}
	else
	{
		KeyON.setBypassed(true);
		KeyOFF.setBypassed(true);
	}

	//you can also move these out here:

	Keys.set("visible", value);
	NoiseSlide.set("visible", value);
};

Or if you want to be even more efficient:

//Since you're using a switch, you can treat *value* like a boolean.

/*
The 1-value trick inverts the boolean of the switch. 
Which means when the switch is active (1), 
setBypassed is false (0) & vice-versa.
*/

inline function onSwitchControl(component, value)
{
	KeyON.setBypassed(1-value);
	KeyOFF.setBypassed(1-value);
	Keys.set("visible", value);
	NoiseSlide.set("visible", value);

	if (value)
	    Synth.playNote(6, 100);
};

@iamlamprey Oh cool.
I didn't know I could treat the switch value as a boolean.
Thanks for the trick.

And I try if rewriting that fixes my issue!

@iamlamprey
The code is a lot cleaner now, but still the same problem.

On its own:

• playing the note works
• switching visibility works

Together, everything works as expected, except the note is not playing...

@VorosMusic So to clarify:

INSIDE HISE
Everything works properly.

IN COMPILED PLUGIN/EXE
Hiding/showing elements works, but no audio from playNote() method?

If that's the case, it suggests either the Loop Player can't find the audio file (https://docs.hise.audio/working-with-hise/settings/project.html#embed-audio-files), or the Bypass of the Loop Player is inverted or not working correctly.

@iamlamprey Thank you for your help!
I don't know why. I redid some other elements of my code and suddenly it worked.
So yes for now its working properly in Hise itself.
