Change panorama position of a noteOn Message

@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);

@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('');

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

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:

	return (normPos + 1.0) * 0.5;
}

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.
