suck notes with keyassigner script in silent synth

[Morphoice]

@David-Healey dead code

is there a faust node in the polyphonic scriptfx?

toes it have a dsp code?

if not put this

// Faust Source File: Test
// Created with HISE on 2026-05-15
import("stdfaust.lib");

gate = button("[20]gate");							// note on off
freq = hslider("[21]freq", 200, 20, 20000, 0.1);	// note frequeny
gain = hslider("[22]gain", 0.0, 0.0, 1.0, 0.01);	// note velocity

attack 			= hslider("AttackTime[style:knob]",0.2,0,6,0.001);
attackSlope 	= hslider("AttackSlope[style:knob]",0.7,0,1,0.001);
decay 			= hslider("DecayTime[style:knob]",0.3,0,6,0.001);
decaySlope 		= hslider("DecaySlope[style:knob]",0.3,0,1,0.001);
sustain 		= vslider("SustainLevel[style:knob]",0.5,0,1,0.001);
release 		= vslider("ReleaseTime[style:knob]",1,0,6,0.001);
releaseSlope 	= vslider("ReleaseSlope[style:knob]",0.3,0,1,0.001);
velDepth 		= vslider("velDepth[style:knob]",1,0,1,0.001);
legato 			= vslider("Legato[style:knob]",0,0,1,0.001);

ramp   			= en.adsr(0, release * 0.15, 0, 0, 1 - gate);
dramp   		= en.adsr(attack, decay * 0.1, 1,0, gate);
rslope			= releaseSlope - ramp * 0.25;
dslope			= decaySlope - dramp * 0.20;

velocity 		= 1*(1-velDepth*((1-gain))); 

envelope 		= en.adsr_bias(attack, decay, sustain, release, attackSlope, dslope, rslope, legato, gate) 
				: hbargraph("CV",0,1);


osc = os.polyblep_triangle(freq) * envelope;

process = osc,osc;

@Morphoice Oh hang on, my current build doesn't include FAUST I can't rebuild at the moment because I'm in the middle of something, but I think you've nailed down that it's a faust side issue.

[Morphoice]

@David-Healey oh yes, the pleasures of building with faust and ending up without faust .... ;)))

im very strongly convinced the issues is within how hise implements faust as explained in the post before, not the faust dsp itself. then again that would only explains the issue that notes are not sustained even though the pedal is pressed...

the other problems are the orphan notes that might still be a problem of the keyassigner... some never get released when the pedal is released.... could be some sort of orphans from a tretrigger of the same note...

my forte is coding dsp, all that stuff around that makes the world tick -- no clue

[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

[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
