Scriptnode Synthesizer (how to :)

hisefilo

@Christoph-Hart can you confirm this is the actual state of the Scriptnode Synth Module with Faust? Or it's just me pulling a boneheaded move?

hisefilo

@Christoph-Hart I finally found the bastard! Parameters makes Scriptnode synth to crash. Is this a simple fix???

@Christoph-Hart any way to get this sorted? :folded_hands: :folded_hands: :folded_hands: :folded_hands: :folded_hands: :folded_hands: :folded_hands: :folded_hands:

Christoph Hart

@hisefilo can you upload a patch that demonstrates this?

hisefilo

@Christoph-Hart Sure.

Save this (or any other faust code) into [Project Folder]/DspNetworks/CodeLibrary/faust/

Compile DspNetworks .dll
Compile a standalone app and run it (crash!)

I've tryied:
-Not allowing compilation on Dspnetwork once dll is already compiled, but parameters are not working
-Compiling .dlls on a ScriptFX and then load the same network on the ScriptNode Synth

hisefilo

@Christoph-Hart look at this analog beauty!!! Yep. faust analog synth!
Fingers crossed for parameter fix to start using this :folded_hands:

Christoph Hart

@hisefilo Alright, I've digged into it. First of all: don't use the scriptnode synthesizer after you've compiled a node. Just like with FX: once you've compiled them you should use the Hardcoded module to wrap the C++ class directly without going through scriptnode.

Now the problem is that there is no hardcoded synthesizer (yet), but that's where the mysterious "Silent Synth" comes in: you can use it in conjunction with a PolyphonicHardcodedFX module and (if the exported network has the HasTail flag enabled that suggests that it's ringing out), it will render a silent voice that then goes through the FX where you can add the synthesizer signal.

So after exporting the DLL you need this signal chain:

Be aware that in order to kill the voices after they ring off you need to add a voice management node to the network that sends a reset message. The best option is to connect a voice_manager to a envelope's CV output, but since you're in faust land, you can just use the node with the awesome name silent_killer, which checks the buffer and just sends a note off signal when the buffer gets silent (there's a slight CPU overhead, but it's negligible next to your sine wave oscillator madness).

Edit: oh and you need to pull the latest HISE build, I've fixed an issue in the silent killer node where it didn't generate the correct polyphonic version.

@Christoph-Hart

Too many parameters are not supported in custom compiled dll nodes, right?

All custom nodes with more than 15 parameters crash here.

hisefilo

@Christoph-Hart Well. just 3 words! We Love You!!!!!!!!!!

You've just opened the pandora's box. I was toying around with the Polyphonic Hardcoded Module but never on the silent synth (dumb of me)

One important note: the silent_killer thing will only work if you have used the convention "gate" label for the Faust trigger. AHDSR with GT connected to a voice_killer worked for me as far as I'm not using that convention.

Also, Gain chain does not affect the synth (as far as it's placed on the FXs chain I guess). Is this ok? I need to do gain modulation directly on Faust code or adding extra nodes in Scriptnode. LFOs ADSRs, etc

@resonant I haven't reached the 15 parameters mark yet. but I will.

resonant

@hisefilo said in Scriptnode Synthesizer (how to :):

@resonant I haven't reached the 15 parameters mark yet. but I will.

This issue happens on effect plugins for me. But 15 or 16 is a low amount for advanced projects, it should be at least 32.

Christoph Hart

@resonant I'm working on big projects and never hit that limitation. Try modularizing your effects or use a slider pack if you want to control a parameter set that is somehow connected (eg. filter bank).

If you can't modularize for some reason you can raise the hardcoded limit here:

hisefilo

@Christoph-Hart I'm really stuck trying to implement sustain on Scriptnode Synthesizer and Faust.
Is there any tip or advice? I get hanging notes if I use the silent_killer and I get no sustain if I use an AHDRS.... any clue??
