Create Interfase on HISE to be used on JUCE

hisefilo

@Christoph-Hart will be my homework then :( thanks mate

hisefilo

@LightandSound A bit hard for me since it's needed to compile every time to see any changes. But I know it's super powerful

Welcome to the slow world of "real" programming :p

Always build debug while testing, it's much faster.

hisefilo

@d-healey thanks!!! see you there :P

I'm really impressed with Faust simplicity. you can create a super complex DSP algorithm with just one line of code. If we are able to use HISE scripting and GUI power plus Faust...

hisefilo

@Christoph-Hart said in Create Interfase on HISE to be used on JUCE:

create a wrapper for the code around it and then compile HISE with the node.

Any clue on how to wrap this simple one oscillator C++ example into a node??? Or any node-wrapping tutorial/example?

@hisefilo A couple years back, Christoph suggested I look at his MDA effect wrapper for inspiration.
check out

HISE-scriptnode\hi_modules\effects

hisefilo

@dustbro thanks mate!! will take a look (C++ still being a pain for me)

Christoph Hart

Hmm, I think it's a little bit over your head to make a proper wrapper for that code (also I think I need to tinker with the compiler flags to see if I can change the code a little bit as there are a few annoying things in it). The most promising solution would be if I just create a wrapper node for faust code that you then can use.

That would be awesome and a way to many faust users to get into HISE (Faust lacks of GUI designer)

JOS will be so happy if that happens :)

ustk

@hisefilo Just to understand, what is the benefit of using Faust?
For what I see, everything can be made directly with scriptnode/snex right?
Easier than snex maybe?

d.healey

@ustk Faust is less buggy :p

But I've stopped playing with Faust for now because I'd rather use the new (less buggy?) version of SNEX when it's ready.

hisefilo

@ustk it's being developed for years and a huge library is there (Many of them developed by JOS)
i.e. you may have an analog modelled filter in just a few lines of code

https://faust.grame.fr/tools/playground/index.html

hisefilo

@d-healey I haven't realised yet what SNEX will allow me to do. C++ is kinda obscure zone for me.

Faust does the compile thing to turn this one line thingy into a physically modelled trumpet on C++

process = pm.trumpet <: _,_;

Dan Korneff

@Christoph-Hart said in Create Interfase on HISE to be used on JUCE:

The most promising solution would be if I just create a wrapper node for faust code that you then can use.

Maybe one for my Matlab models too? ;)

d.healey

@hisefilo I played around with those physical models, that particular function though is just a wrapper around the STK. It's good for demonstration but you don't have any control over the components.

I rebuilt the Faust pm.flute inside Faust so that I could control each element and change the bits I didn't like, it wasn't one line :p I want to rebuild it in HISE at some point.

hisefilo

@d-healey said in Create Interfase on HISE to be used on JUCE:

I want to rebuild it in HISE at some point.

Yeah, me too.

hisefilo

@d-healey Do you know if SNEX will require C++ knowledge for creating custom stuff?? Like an Karplus-Strong modified algo or an oscillator able to read data tables?

d.healey

@hisefilo https://docs.hise.audio/scriptnode/manual/snex.html

hisefilo

@d-healey said in Create Interfase on HISE to be used on JUCE:

@hisefilo https://docs.hise.audio/scriptnode/manual/snex.html

Yes, being there. Needs a lot of C++ skills

d.healey

@hisefilo It's very simplified though, doesn't look much worse than Javascript

for(auto& sample: block)
{
    sample = (float)Math.sin(uptime);
    uptime += 0.002;
}

The only bit there I don't really understand is auto& but I'm sure it's not too tricky to figure out.
