Make the Gain knob smooth the gain?

[CatABC]

@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]

@CatABC It depends on exactly what you want to do, but it should probably go outside of both the samplers.

In the on note on callback you need to store the ID of each note in a midi list.

Then when you want to fade out a particular note you can retrieve the ID and add the volume fade.

If you only need to handle one note at a time (monophonic) then you can probably skip the MIDI list and just use a reg variable.

@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?

@CatABC You don't need to put the midi processors within each sampler. Just use one below the interface script. You don't need a loop in on note on.

Start really simple.
Make a practice project with only one sampler.
Every time you play a note the previous note is turned off.

Once you have that working we can start getting more complicated.

[CatABC]

@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.

Share the snippet you have made for one sampler and we'll go from there.

@CatABC You can use Message.getEventId() to get the event ID if you don't want to make the note artificial.

Now modify this script so that when you press a keyswitch key (whichever key you want), while another is held down already, it turns off the note that is held down and plays a new note of the one that was held.

For example, if you're holding down C3 and you play C0, you turn off C3. Then you play a new C3 note. - And you ignore the C0 note.

All of this in a single sampler, for now.

[CatABC]

@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]

@CatABC

This returns an event ID that you need to store, so that you can turn the note off when the key is lifted. Otherwise you'll get hanging notes.

Synth.playNote(60, 20);

@CatABC said in Make the Gain knob smooth the gain?:

if(Message.makeArtificial() == eventIds)

Here you should use Message.getEventId() instead of makeArtificial

@CatABC said in Make the Gain knob smooth the gain?:

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

What's this meant to do?

[CatABC]

@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]

@CatABC said in Make the Gain knob smooth the gain?:

Synth.playNote(60, 20);

You need to store the ID of the note in a variable so that you can turn it off later.

@CatABC said in Make the Gain knob smooth the gain?:

Message.makeArtificial()

I think you're misunderstanding the purpose of this function.

[d.healey]

@CatABC Here's a basic example using a sine-wave generator.

I've put everything in the interface script but in a real project it should be in a separate MIDI processor.

@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]

@CatABC said in Make the Gain knob smooth the gain?:

Yes, this was just an example to get you started. Synth.isKeyDown() might help here.

[Chazrox]

Have you messed with scriptnode fx at all? This seems like its pretty simple in scriptnodeFX. You can rig as many samplers as you need and trigger them with built in X-Fade nodes and so much more.... ??? Skim thru the documentation for the entire scriptnodeFX section and see all the stuff you have at your fingertips!

HISE | ScriptNode | Scriptnode

An introduction to scriptnode

(docs.hise.dev)

[Chazrox]

@CatABC for example....

wanna fade between 3 samplers that start at the same time?....different times? You can do that too...either way check this method out. The fader node has different fade modes, blend & switch modes.

[CatABC]

@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?

[CatABC]

@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

[d.healey]

@CatABC Don't use that snippet, use the one I gave you as a starting point.
