I used something like this to prevent lastNote from being triggered when only ks is pressed. Now, I tried adding VolumeFade to the old events, but this doesn't seem to work

function onNoteOn()
{
	local n = Message.getNoteNumber();
	
	if (n == ks)
	{
	

		if (Synth.getNumPressedKeys() > 1 && lastNote >= 0 && eventIds.getValue(lastNote) != -99)
		{
			//Synth.noteOffByEventId(eventIds.getValue(lastNote));
			Synth.addVolumeFade(eventIds.getValue(lastNote), 2000, -99);
			
			eventIds.setValue(lastNote, Synth.playNote(lastNote, Message.getVelocity()));
		}
	
		return Message.ignoreEvent(true);
	}
	
	lastNote = n;
			
	eventIds.setValue(n, Message.makeArtificial());	


}	

@d-healey This seems to be back to the HISE snippet I provided at the beginning

function onNoteOn()
{
	local n = Message.getNoteNumber();
	
	local v = Message.getVelocity();

	Message.ignoreEvent(true);
	
	for (i = 0; i < 127; i++) {
			
	       // turn off previous event
	       local e = eventIds.getValue(i);
	       	       
	       if (e != -1)
	           Synth.noteOffByEventId(e);
		//Synth.addVolumeFade(e, 2000, -90);
	       // play new note if key is down
	       if (Synth.isKeyDown(i)) {
		       
	           local newNote = Synth.addNoteOn(1, i, v, 0);
	           eventIds.setValue(i, newNote);
	       }
	       
	   }

}

I don't know where to put Synth.addVolumeFade(); to make it succeed

@Chazrox This looks like a good choice. I tried it, but there is a problem. When KeySwitch is triggered, it requires the Fade knob to automatically and smoothly go from 0 to 1. How can I control it?

@d-healey
I tested your snippet, but in this case the second C0 triggers the playing of C2 again, is it possible to not trigger the playing note when there is no note above?

@d-healey

Synth.playNote(60, 20);

The 60 here should be the note that was pressed before,

Synth.playNote("eventIds's note", 20);

I can't stop the artificial notes

function onNoteOn()
{
	
	if(eventIds != -1)
	{
		Synth.noteOffByEventId(eventIds);
	}	
	eventIds = Message.getEventId();

	if (Message.getNoteNumber() == 36)
	{
		
		Message.ignoreEvent(true);	
		
		Synth.playNote(60, 20);
		
	}

}

function onNoteOff()
{


	if(Message.getEventId() == eventIds || Message.getEventId() == Message.makeArtificial())
	{
		eventIds = -1;
	}
	
	
}
 
 

In this case, the D3 note cannot be turned off

@d-healey
When I use Message.getEventId();, and play two different notes, the previous note does not close.And I don't know how to convert the events into notes

function onNoteOn()
{
	if(eventIds != -1)
	{
		Synth.noteOffByEventId(eventIds);
	}	
	eventIds = Message.makeArtificial();

	if (Message.getNoteNumber() == 36)
	{
		
		Message.ignoreEvent(true);	
		Synth.playNote(60, 20);
	}
	
}
function onNoteOff()
{
	if(Message.makeArtificial() == eventIds)
	{
		eventIds = -1;
	}

	if(Message.makeArtificial() == 0)
	{
		Engine.allNotesOff();
	}
	
}

@d-healey
This is my method using only one Sampler, I used artificial notes

@d-healey When I only use one Sampler, it can achieve that when the second note appears, the previous note will no longer sound, but when I add a second Sampler, it needs to be triggered at the same time with the KeySwitch below, which makes the script completely illogical and gives me a headache.

@d-healey
Thanks David, I tried a lot and I'm now clueless again,
I think my logic is very confusing now. I hope to complete the KeySwitch switching on an uninterrupted note. When the new KeySwitch enters, fade out the sample of the previous Sampler and fade in the sample of the new Sampler. I hope that the faded-in sample is played from the beginning.

so I made a snippet, could you help me with this?

@d-healey Emmm, forgive my stupidity, I don't know how to use it. Should it be in the ScriptProcessor of Sampler1 or in the ScriptProcessor of Sampler2? How can it fade out the samples of Sampler1?

@d-healey Or is there any other way to Xfade?

@d-healey
I use code control. When the keyswitch is triggered, I need to slowly decay the volume of Sampler1 to -100 and slowly increase the volume of Sampler2 to 0.

function onNoteOn()
{
for (i = 0; i < 4; i++)
	{	
	       ksGain[i].setAttribute(ksGain[i].Gain, -100);
	}
ksGain[0].setAttribute(ksGain[0].Gain, 0);	
}

hey guys, i want to make the value of this knob smoothly gain from -100 to 0 (-100, -99, -98...-2,-1,0) instead of going directly from -100 to 0, how should i do it?

@dannytaurus Thanks for paying attention to my question. I am still working on it. I will break down my logic:

1. I mapped KeySwitch to C0-B0, default key position (such as C0 Sustain)
2. Write a note C3 in the MIDI track
3. Start playing C3 of Sustain
4. The C3 note continues, and I write a KeySwitch on D0 (D0 is Tremolo)
5. The sample of Sustain fades out, and the sample of Tremolo enters
6. All MIDI ends, and the KeySwitch stays at Tremolo of D0. When there is no new KeySwitch trigger, the notes written afterwards are all "Tremolo"

@d-healey
Can I set it, set it to 0 in onNoteOn, but I don't know how

@d-healey Yes, I want each articulation to start from 0

@d-healey Yes, I mean when I switch to the second articulation, the sample of the second articulation does not start playing from the beginning

@Chazrox Ah, I don't quite understand what you mean. I'm making a bowed string instrument and I want to be able to use KeySwitch to transition between multiple articulations on a single MIDI note.

@d-healey I tried this, but when I switch to the second Sampler, the sample does not start playing from the beginning. What do I need to do to make the sample I switch to play from the beginning?

@Orvillain yes,I already understand the design of HISE, it is more free than Kontakt！
