Make the Gain knob smooth the gain?

[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!

https://docs.hise.dev/scriptnode/index.html

[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.

[Felix W]

@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?

[Felix W]

@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

[David Healey]

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

[Felix W]

@d-healey
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());	


}

@CatABC I was thinking more like this

[Felix W]

@d-healey Yes, it is indeed more logical to use isKeyDown,
I put the code into the MIDI processor of the two waveform generators, but now I can't control the fade-out of the sound of the previous generator and the fade-in of the sound of the next generator when the KeySwitch is triggered. I used MIDIMuter, but I found that this is the wrong way to do it. When I use two waveform generators, I need to ensure that only one generator makes a sound at a time. Once I use MIDIMuter, they either make no sound or the sound can't be stopped.

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

I put the code into the MIDI processor of the two waveform generators,

Why?

[Chazrox]

@CatABC I would script a UI button with 3 discrete stops. This knob will control your paramter knob from your scriptnode. Make sure the parameter knob in scriptnode is also set from 0-3 with stepsize 1.0. Changed the fader node to switch mode. Add a value ramp/smoothing node in between the faders mod outputs and the target gain knobs for each sampler. It should trigger the faders values either 1-2-3 to smoothly fade between one another. The part you have to script is what midi keys trigger each value of your parameter knob. Sorry if this is sloppy, this is off the top of my head without making a snippet example.

• based on the example I gave you above.

Honestly have a look at the scriptnode list in the documentation. You can really get crazy with the cheeze wiz if you see whats available.

[Felix W]

@d-healey I thought that if working between multiple generators, each generator should have separate controls, maybe I'm wrong?

[Felix W]

I need to rethink my thinking. What I want to do is to use KS to split a note.

[David Healey]

@d-healey I thought that if working between multiple generators, each generator should have separate controls, maybe I'm wrong?

I don't think it's needed for this use case because we want to work with both as a single unit. You might even only need one sampler, depending on how many samples you have and how you want to map them.

I really think you do.

@Chazrox Yes, I have searched the HISE documentation many times, but because I am a novice, I don’t know how to use many APIs, and I am crying because of my stupidity.

You're not stupid. We all start at the beginning. Everything is hard until it becomes easy. Keep going.

[Felix W]

@d-healey

Thanks for the encouragement David,Please teach me again, when I trigger the second C#0, how can I add a fade-out to the note that responded to the first time?

[David Healey]

@CatABC Replace the Synth.noteOff with Synth.addVolumeFade - set the volume to -100 and that will also turn the note off.

[Felix W]

@d-healey
I think I have it working. Next I need to move on to multiple generators to test!
Thank you so much for your teaching ，David, I love you

function onNoteOn()
{
	local n = Message.getNoteNumber();
	
	if (n == ks)
	{
		if (eventIds.getValue(lastNote) != -99)
		{
			 Synth.noteOffByEventId(eventIds.getValue(lastNote));
		}
	
		if (Synth.isKeyDown(lastNote))
			eventIds.setValue(lastNote, Synth.playNote(lastNote, Message.getVelocity()));		
		
	
		return Message.ignoreEvent(true);
	}
	if (n == 25)
		{	 
			if (eventIds.getValue(lastNote) != -99)
				{
					Synth.addVolumeFade(eventIds.getValue(lastNote), 500, -100);
				}
			return Message.ignoreEvent(true);
		}
	lastNote = n;
	eventIds.setValue(n, Message.makeArtificial());	

}

[David Healey]

@CatABC Looks like it's almost there. But you have added that n == 25 block. If 25 is your keyswitch then you should be using the code I put already above that and just replace the noteOff with the volumeFade. No need for the extra block.
