suck notes with keyassigner script in silent synth

[David Healey]

@Morphoice Tell me what the key assigners role is.

[Morphoice]

@David-Healey handle polyphonic aftertouch and pitchbend by sending their values to a knob in the faust (not present in the snippet example)

[David Healey]

@Morphoice Does that need to be scripted? Isn't there a way directly in scriptnode to get those values and forward them to the faust node?

[Morphoice]

@David-Healey nope, we had this discussion here a long time ago and this was the only working way

[Morphoice]

@David-Healey i believe it was this thread
https://forum.hise.audio/topic/11793/polyphonic-aftertouch/34?_=1778856642370

[Morphoice]

@David-Healey there's also another bug in the hise/faust midi implementation.... if a key is held and the pedal released, the note stops. although the key is still held.... weird.

[David Healey]

@Morphoice Does this happen if you swap your faust synth for a waveform gen, keeping everything else the same?

[Morphoice]

@David-Healey there is no waveform generator in a silent synth

[Morphoice]

@David-Healey i think i isolated the problem and filed an issue, it's in fact three problems

@David-Healey in the mean time i found a workaround to override the faust bug by handling the sustain logic in the keyassigner. this however breaks if more than 128 notes are played until the last pedal release. but i guess i could just reserve more slots

const globalRouting = Engine.getGlobalRoutingManager();
reg midiList = Engine.createMidiList();
reg pedalDown = false;
reg pendingReleases = [];
pendingReleases.reserve(128);

inline function setPolyAfterTouch(eventId, slotIndex, value)
{
	globalRouting.setEventData(eventId, slotIndex, value);
}

function onNoteOn()
{
	// Make the event artificial so Synth.noteOffByEventId can release it later.
	// The HISE API only accepts artificial event ids (see ScriptingApi.cpp:5499-5510).
	midiList.setValue(Message.getNoteNumber(), Message.makeArtificial());
}

function onNoteOff()
{
	local n = Message.getNoteNumber();
	local id = midiList.getValue(n);

	if (pedalDown)
	{
		// Defer: keep the voice alive until pedal release.
		pendingReleases.push(id);
		Message.ignoreEvent(true);
	}
	else
	{
		// Release the artificial voice. Let the real noteOff propagate too so
		// the synth can match older retriggered voices by note number.
		Synth.noteOffByEventId(id);
	}
}

function onController()
{

	if (Message.getControllerNumber() == 64)
	{
		if (Message.getControllerValue() >= 64)
		{
			pedalDown = true;
		}
		else
		{
			pedalDown = false;
			for (id in pendingReleases)
				Synth.noteOffByEventId(id);
			pendingReleases.clear();
		}
		Message.ignoreEvent(true);
	}

}
 function onTimer()
{
	
}
 function onControl(number, value)
{
	
}

@Morphoice said in suck notes with keyassigner script in silent synth:

if more than 128 notes are played until the last pedal release.

Can't you kill previous voices if the same note is played more than once?
