Iteratively updating sample properties

d.healey

The reason for your error (well the error tells you) is that this_sampler.RootKey isn't defined, as in that is not valid script.

The first problem is what you are looking for is a constant of the Sampler class, not your particular sampler. The second issue is that Christoph made a typo and the constant you want is called Root. You can use the autocomplete in HISE to help you here.

@d-healey sorry, I'm a bit confused. There's something I am missing I guess.

I want to get these:

And I was under the impression that these would be attributes of my particular sample instances inside of my samplemap ?

I'm not looking to adjust the global sampler settings.

d.healey

@Orvillain Did you try what I put above? The selection is made on your specific sampler, but the constants (which are just numbers) are part of the Sampler class.

Orvillain

@d-healey

I tried this:

	for(sample in this_sampler.createSelection(".*"))
	{
		sample.set(Sampler.Root, 36);
	}

And my root notes still end up as E3, so I guess it didn't work.

d.healey

@Orvillain Have you checked that the selection is working and returns an array of samples?

Orvillain

@d-healey

I get an object reference - Object 0x23127408

I guess I have made the assumption that this is my sample object.

Again, my code snippet:

	for(sample in this_sampler.createSelection(".*"))
	{
		Console.print(sample);
		//sample.set(Sampler.Root, 36);
	}

If I do this:

Console.print(this_sampler.createSelection(".*"));

Then yes, I get an array.

this_sampler is definitely an instance of my sampler, because the code prior works fine. It loads the samples, and I can even do what I want to do by doing this:

	this_sampler.setSoundPropertyForAllSamples(4, 60 + parseInt(pad_id));
	this_sampler.setSoundPropertyForAllSamples(3, 60 + parseInt(pad_id));
	this_sampler.setSoundPropertyForAllSamples(2, 60 + parseInt(pad_id));

This bit of code works fine. But it will set all samples on a pad to the same root/hi/lo values, and eventually that isn't what I want.

d.healey

@Orvillain Do other constants work?

Orvillain

@d-healey

They don't no.

Am I to assume then that this syntax is correct for the actual setting of the property?

		sample.set(Sampler.HiKey, 36);

Yes that's what I'm doing here - but I haven't tried changing the key number. Does changing the Pitch work for you?

Sorry, had to pop away. But here's what I've got:

	for(sample in this_sampler.createSelection(".*"))
	{
		sample.set(Sampler.Pitch, 24);
		//sample.set(Sampler.LoKey, 60 + parseInt(pad_id));
		//sample.set(Sampler.HiKey, 60 + parseInt(pad_id));
		//sample.set(Sampler.Root, 60 + parseInt(pad_id));
	}

But there is something interesting going on. Let me see if I can breakdown what is happening.

First... I load my plugin from init. All my samplers are empty.
I drag a sample to one of my pads, and it loads:

But when I select the sample in the editor, you can see that Pitch is still at 0ct.

I drag another sample onto the same pad (and thus same sampler) and I get this:

Notice my sample is not selected in the editor, but the pitch box does say 24ct, as I was expecting.

But... select the sample, and....

It resets back to 0ct.

So... it seems to me something isn't being applied correctly.

Again, here is my whole code:

Content.makeFrontInterface(600, 600);

const var samplers = [];

inline function load_sample(file_obj)
{
	local pad_id = this.get("id").split("_")[2];
	local this_sampler = samplers[pad_id];
	this_sampler.clearSampleMap();
	local abs_path = FileSystem.fromAbsolutePath(file_obj.fileName);
	local parsed = [this_sampler.parseSampleFile(abs_path)];
	this_sampler.loadSampleMapFromJSON(parsed);	
	
	// I think this is supposed to work. But it doesn't.
	for(sample in this_sampler.createSelection(".*"))
	{
		sample.set(Sampler.Pitch, 24);
		//sample.set(Sampler.LoKey, 60 + parseInt(pad_id));
		//sample.set(Sampler.HiKey, 60 + parseInt(pad_id));
		//sample.set(Sampler.Root, 60 + parseInt(pad_id));
	}
}

for (i = 0; i <16; i++)
{
	var current_pad_panel = Content.getComponent("pad_panel_" + i);
	var current_sampler = Synth.getSampler("Sampler" + i);
	samplers[i] = current_sampler;
	current_pad_panel.setFileDropCallback("Drop Only", "*.wav", load_sample);
}

Syntax and standards aside, can you spot anything that would cause this kind of issue?

Here is the HISE snippet:

@Orvillain Ah I think I understand the problem now. I missed that this is meant to happen after you load a sample via drag/drop.

This is what is happening:

Load sample
Do the set sample stuff
Sometime later the sampler finishes loading the sample.

You see HISE doesn't wait for the sample to load before the bit of code that you've written to change the sample properties. That code just fires right after you've told it to load the sample, but the sample is still loading at that point. You need to wait until the sample is loaded before trying to change its properties.

This is done using a panel and the loading callback: https://docs.hise.audio/scripting/scripting-api/scriptpanel/index.html#setloadingcallback

Orvillain

@d-healey

Ahhhhhhhh. Yes, that makes sense. I will read the API and try to implement this callback. My "pads" are panels already.

Btw, you can probably use a single panel for all your pads.

Thanks for the help on the setloadingcallback - I've got that working.

I guess my unfamiliarity with HISE is why I went with individual panels, but if you care to expand on how I might use a single panel, I'm all ears.

As it stands, I now have this:

Content.makeFrontInterface(600, 600);

const var samplers = [];


inline function load_sample(file_obj)
{
	local pad_id = this.get("id").split("_")[2];
	local this_sampler = samplers[pad_id];
	this_sampler.clearSampleMap();
	local abs_path = FileSystem.fromAbsolutePath(file_obj.fileName);
	local parsed = [this_sampler.parseSampleFile(abs_path)];
	this_sampler.loadSampleMapFromJSON(parsed);
}

inline function set_sample_trigger_zones(isPreloading)
{
	local pad_id = this.get("id").split("_")[2];
	local this_sampler = samplers[pad_id];

	if(!isPreloading)
		for(sample in this_sampler.createSelection(".*"))
		{
			sample.set(Sampler.LoKey, 60 + parseInt(pad_id));
			sample.set(Sampler.HiKey, 60 + parseInt(pad_id));
			sample.set(Sampler.Root, 60 + parseInt(pad_id));
		}
}

inline function trigger_pad(event)
{
	if (event.clicked)
    { 
        local pad_id = this.get("id").split("_")[2];
		local this_sampler = samplers[pad_id];
		Synth.playNoteFromUI(1, 60 + parseInt(pad_id), 100);
    }
}

for (i = 0; i <16; i++)
{
	var current_pad_panel = Content.getComponent("pad_panel_" + i);
	var current_sampler = Synth.getSampler("Sampler" + i);
	samplers[i] = current_sampler;
	current_pad_panel.setFileDropCallback("Drop Only", "*.wav", load_sample);
	current_pad_panel.setLoadingCallback(set_sample_trigger_zones);
	current_pad_panel.setMouseCallback(trigger_pad);
}

And this basically gives me what I want. However, I suspect right now that my properties are being set 16 times, because the callback is triggered 16 times when I drop a wav file onto a panel.
