Change panorama position of a noteOn Message

d.healey

Yeah I think this would be a useful addition as well.

Frankbeat

This would be really cool! I'm looking forward to develop a keyboard mapped synthetic tom that I made in Kontakt. And I found this feature by accident but it turned out to be a very crucial parameter of this instrument.

ulrik

@Frankbeat if you are using a sampler, you can do this but it's not recommended to do it in the NoteOn callback, but you could make a function to spread the pan for each sample in the sampler and save this in the sample map.
Or you could connect the function to a "spread" knob and set it but not while playing.

I use this script for one of my sampled instruments, it's only 16 notes and each note has it's own pan knob, but you could modify this script to your likings of course

//  Pan --------------------------------------
inline function onPanKnbsControl(component, value)
{
    //  Selects all samples
    Sampler1.selectSounds("");

    //  get number of samples selected
    local NUMSelected = Sampler1.getNumSelectedSounds();
    
    // lookup array (note numbers)
    local indexList = ["48", "50", "52", "53", "55", "57", "59",
    "60", "62", "64", "65", "67", "69", "71", "72"];
    
    for (i = 0; i < NUMSelected; i++)
    {
        local index = PanKnbs.indexOf(component);
        local root = Sampler1.getSoundProperty(Sampler1.Root, i);
        Console.print(root);
                
        if (root == indexList[index])
        {
            Sampler1.setSoundProperty(i, Sampler1.Pan, PanKnbs[index].getValue());
        }
    }
}

for (p in PanKnbs)
{
    p.setControlCallback(onPanKnbsControl);
}

@ulrik Wow… thank you! I will have to investigate this but no, I'm not dependent on using the onNoteOn callback for making it happen… Only purpose is to be able to set the stereo width across the keyboard. So, your example reads very promising on first glance. I'll report!

Change specific samples "pan"

Is there a way to set a specific samples "pan", in the sampler, via scripting? like the way you can do with the gain Message.setGain()

Forum (forum.hise.audio)

yeah thats about modulating the output of the sampler with a random value - this thread seems to me to be more about assigning specific notes to specific positions...unless I'm misunderstanding this.

If I remember correctly you can use a simple gain module and change the balance knob per note.

@Frankbeat I would do it something like this

Thank you very much!
What is that Timer Object for? Is it a workaround to omit a call from onNoteOn?

Christoph Hart

You need a stereo fx with a scripted voice start modulator.

ulrik

@Frankbeat you don't need the timer, it's just there for the visual meters in this example.

Frankbeat

@ulrik If I want to apply the same panorama settings to a Sampler2, would this be a more complex operation?
I have tried to just duplicate the setSoundProperty call like:

	    Sampler1.setSoundProperty(i, Sampler1.Pan, pan);
	    Sampler2.setSoundProperty(i, Sampler2.Pan, pan);

But that doesn't work. It makes the knob have no effect anymore.

ulrik

@Frankbeat with the same knob?
Can I see your code?

Frankbeat

@ulrik Yes, both with the same knob. Here is the function (script references for Sampler1 and Sampler2 are given, but not shown here):

const spreadKnb=Content.getComponent('spread');
inline function onSpreadKnb(component, value) {
	Sampler1.selectSounds('');
	local NumSelected = Sampler1.getNumSelectedSounds();
	local sampleRoots = [];
	for (r = 0; r < NumSelected; r++) sampleRoots.push(Sampler1.getSoundProperty(Sampler1.Root, r));
	sampleRoots.sort();

	local lowestNote = sampleRoots[0];
	local highestNote = sampleRoots[sampleRoots.length - 1];
	
	local range = highestNote - lowestNote;
	local centerNote = lowestNote + range/2;
	
	local step = 150 / range;
	
//	Note numbers of both maps are:
//	45,46,47,48,49,50,51,   52,   53,54,55,56,57,58,59];
	
	//	Spread from the center and out
	for (i = 0; i < 59; i++) {
	    pan = (-(52-sampleRoots[i])) * value;
	    Sampler1.setSoundProperty(i, Sampler1.Pan, pan);
	    Sampler2.setSoundProperty(i, Sampler2.Pan, pan);
	}
};	spreadKnb.setControlCallback(onSpreadKnb);

ulrik

@Frankbeat You can't have the same variables for both samplers, you have to duplicate them and also have a separate for-loop for the Sampler2 samples
also Sampler2.selectSounds('');

Frankbeat

@ulrik Alright, now it works… Thank you very much, again!

Christoph Hart

Changing the sample properties like this might lead to a few edge case issues (eg. if you load a sample map in a preset and then change the pan it might cause order-of-initialization issues), also it's a very heavyweight operation so you can't automate it.

The stereo FX with scripted voice start modulator solution looks like this:

With this solution, does the knob have to be added inside the Script Modulator? So I have to add the same knob to each of my Samplers?

Christoph Hart

Yes and it might make sense to connect it to an external script if you have more than two samplers to keep the redundancy low.

ulrik

@Christoph-Hart this seems to be a better way, and cleaner!

ulrik

@Christoph-Hart And using this way, would it be possible to set up a mixer for just one sampler, gain and pan for each note?

Frankbeat

Wow, this works like a charm! Thank you very much!
This way, it is even easier to set the right spread amount across the mapping range. I helped myself a little by printing it to console, since you wrote it has to return values between 0 and 1.

function onVoiceStart(voiceIndex)
{
	local normPos = (Message.getNoteNumber() - 45) / 45;
	normPos *= spreadKnob.getValue();
	local newNormPos=(normPos) * 3.21;
	// dev state only: Console.print(newNormPos);
	return newNormPos;
}

The noteNumber 45 is my lowest mapped key here, but I don't know how I came to end up with this modified formula omitting the +1. But not to complain – it works.
