@trillbilly The easiest way I could think of to create such an effect is to create a ping/pong sample.
Use your Daw to create a looping pingpong sample and than use this with looping enabled in Hise.

@ustk

Now your mentioned problem comes into play not getting my image names correctly, but I should be able to fix that.

@ustk
Maybe inverting the idea?
Tracking a mouse-click and if it's not in a certain area (panel) it's outside?
Would probably reduce the amount of components.

And yeah, I agree, might be a nice feature to have.

@ulrik
Man, that really is a bad and messy solution...
I hope someone can find an easy way to do this, but here would be the version I talked about using a button to trigger the loop toggle for the length of the wave.

@ForeverLive
In my experience, if @Christoph-Hart or @d-healey don't give a simple and straight answer its probably not a beginner friendly process.

So like they said I'd also recommend other priorities first.

@d-healey
I have about 5 - 7 other samplers, thats why I was a bit concerned.

@d-healey
I see, where I was wrong...
I needed to set them to false and not delete them...LOL

@d-healey WOW
Thank you Master Healy!

@BWSounds I have the feeling the inbuilt Arp is not always fully reliable in Hise, when turning on and off.
Could you send a pic of your Arp-Settings maybe I can find something, working with it on a project right now too.

@orange
I haven't worked with timers yet, so I'm not sure if that would work, but I found "callWithDelay" in the API browser, maybe this will do the job...
Haven't had time to try it out yet.

@ustk
That's true...
Even though its not the same Sampler you might be correct. As far as I know there is an AllNotesOff event, when changing Samplers Bypass.
But I already tried a different order, it did not make a difference.

I think I also tried delaying the PlayNote once, but did not work as well and lately I tried a different sample and it played, so it seems to be a quite specific issue.

I'll try to rebounce the sample I'm using, maybe that fixes things.

Are there any known issues with certain samples?
Maybe too long, embedded markers?

@d-healey
Too bad... I hoped I was onto something...

This is a snipped of more or less, whats going on in my project, but I can't quite recreate the issue of the button not playing a note.
It seems to only happen with that one specific sample I'm using

This is related to an old problem I had of a sampler not playing, when a note was triggered by a button.
Now I saw this warning: "! Saving embedded samplemaps is bad practice. Save the samplemap to a file instead."
Could this be the issue, and if so how can I delete the embedded samplemap?

@ulrik
I just took a look and found the LFO behaviour kinda weird.
Seemingly all waves loop on their own except the custom one. (depending on the button)

My only quick idea I had was a timer with the same length as the LFO turning on and off the loop toggle...

@ustk
Good Call!

Turning off custom graphics (unintuitively) fixed my main issue.
Now your mentioned problem comes into play not getting my image names correctly, but I should be able to fix that.

@ustk
My console does not print from within my LAF function

//Load Images
const KeyLaF = Content.createLocalLookAndFeel();
for(i = 0; i < 12; i++)
{
	var prefix = "{PROJECT_FOLDER}keyboard/";
 	
 	var d = "down_" + i;
 	var u = "up_" + i;
 	
 	KeyLaF.loadImage(prefix + d + ".png", d);
 	KeyLaF.loadImage(prefix + u + ".png", u);
}


//White Keys
KeyLaF.registerFunction("drawWhiteNote", function(g, obj)
{
	g.setColour(Colour.black);
 	
 	var x = obj.down ? "down_" : "up_";
 	x += obj.noteNumber % 12;
 	g.drawImage(x, obj.area, 0,0);
 	
 	g.setColour(Colours.red);
 	g.fillRect(obj.area);	
});

Keyboard.setLocalLookAndFeel(KeyLaF);

(I know the keys don't look that great yet, they are just for testing purposes!)

This is a simplified example. In the code I wrote to fill the keys red after painting the images, but the remain untouched.
Except I'm missing something obvious?!

@d-healey
Yes and I also applied the LAF.
The images them selves are working fine, but I cant add any additions like text, or a hover state.

//Load Images
const KeyLaF = Content.createLocalLookAndFeel();
for(i = 0; i < 12; i++)

	var prefix = "{PROJECT_FOLDER}keyboard/";
 	
 	var d = "down_" + i;
 	var u = "up_" + i;
 	
 	KeyLaF.loadImage(prefix + d + ".png", d);
 	KeyLaF.loadImage(prefix + u + ".png", u);
}

Keyboard.setLocalLookAndFeel(KeyLaF);

@d-healey

KeyLaF.registerFunction("drawWhiteNote", function(g, obj)
{
 	var x = obj.down ? "down_" : "up_";
 	x += obj.noteNumber % 12;
 	g.drawImage(x, obj.area, 0,0);
 	
 	if(obj.hover)
 		{
 			g.setColour(0x33000000);
 			g.fillRect(obj.area);	
 		}
 		
});

This is part of my white keys function.
