Faust is here...

[Sawer]

@Sawer
When I use the demos from faust IDE, everything works fine(2x2 channels).
As soon as I try implementing my own parameters, I always get this odd channel mismatch errors.
Same for libraries with 8x8 (it will ask 9x8).

Am I missing something?

[toxonic]

@Sawer Can you post your faust code?

[Sawer]

@toxonic

Here you go, thanks.

[toxonic]

@Sawer indeed, i can't see, where the third input channel comes from. But where did you change the code, respectivly added your parameters?

[Sawer]

@toxonic

import("stdfaust.lib");

process = dm.dattorro_rev_demo;	

This code works.

import("stdfaust.lib");

bw = hslider("BAndWidth",0.5 ,0 , 1,0.1);
inputDiff1 = hslider("Diffusor1",0.5 ,0 ,1 ,0.1);
inputDiff2 = hslider("Diffusor2",0.5 ,0 ,1 ,0.1);
decay = hslider("Decay", 0.5,0 ,1 , 0.1);
decDiff1 = hslider("dDiffusor1",0.5 ,0 ,1 ,0.1);
decDiff2 = hslider("dDiffusor2",0.5 ,0 ,1 ,0.1);
damping = hslider("damping",0.5 ,0 ,1 ,0.1);



process = re.dattorro_rev(bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

This code(with my parameter) doesn't.

[toxonic]

@Sawer i'm actually at work, i'll have a look at it later. Did you already check the SVG diagram (the Button with the eye on the faust node)?

[Sawer]

@toxonic
3x2 Also on the svg.

[toxonic]

@Sawer ahh, okay, i'm still at work, but try to use this as process line instead:

process = _,_:re.dattorro_rev(bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

[Sawer]

@toxonic Trying now, thanks.

[Sawer]

@toxonic

Ahahha, this is way too strange...

[toxonic]

@Sawer Okay, this was not that simple to figure out: There was an error in the description of the reverb in the library. There's missing the parameter for the predelay.
The code should probably rather look like this:

import("stdfaust.lib");

predelay = hslider("Predelay",0.5 ,0 , 1,0.1);
bw = hslider("BandWidth",0.5 ,0 , 1,0.1);
inputDiff1 = hslider("Diffusor1",0.5 ,0 ,1 ,0.1);
inputDiff2 = hslider("Diffusor2",0.5 ,0 ,1 ,0.1);
decay = hslider("Decay", 0.5,0 ,1 , 0.1);
decDiff1 = hslider("dDiffusor1",0.5 ,0 ,1 ,0.1);
decDiff2 = hslider("dDiffusor2",0.5 ,0 ,1 ,0.1);
damping = hslider("damping",0.5 ,0 ,1 ,0.1);



process = re.dattorro_rev(predelay,bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

Note, that this is not really working like it should, because this is just the wet reverb, you would have to add a mixing unit for the dry sound.

[Christoph Hart]

@toxonic or a dry_wet template that does that for you in scriptnode...

[Straticah]

@Christoph-Hart Is it possible to "auto compile" Faust nodes on export to still be able to debug or reroute effects in the HISE project after the export is done?

[Christoph Hart]

@Straticah no because then you would need the end user to have faust installed and setup correctly.

[Straticah]

@Christoph-Hart ah i see, i thought compiling would make it usable without jit. Where do i get information on how i need to prepare Faust nodes to work properly for the end user? :)

[Sawer]

@toxonic Perfect, thanks!

[Christoph Hart]

@Straticah ah that‘s a misunderstanding I thought you wanted to use the JIT node in a exported project. But yes when you export a network with a faust file it will generate C++ code from it that runs on its own.

Now what was your initial question? :)

[Straticah]

@Christoph-Hart I see, sorry for the misunderstanding. I had the problem that my FX plugin uses scriptnodes and faust nodes, but on VST export they are all bypassed.

My solution was now to create hardcoded dlls and reroute the effects to my knobs and delete the scriptnodes.
Im quite new to nodes and faust but was bit frustrated after my VST had some script and faust fx missing on VST export. :)

This is where my question came from if there is a way to automate the compilation from nodes to c++ on VST export/build.
Hope this makes sense and you get what i want to bring across. ^^

[Christoph Hart]

No you need to export a DLL to create the C++ classes from scriptnode / SNEX / Faust nodes before you export your plugin.

My solution was now to create hardcoded dlls and reroute the effects to my knobs and delete the scriptnodes.

Yes this is the recommended approach:

1. Design the effects in scriptnode
2. Compile them to C++ effects
3. Replace the scriptnode module with a HardcodedFX

This removes the overhead of the scriptnode interpreter. The replacement step itself is rather easy because you just need to replace the module, give the hardcoded module the same ID as the scriptnode module, then reload the HISE project which should update all connections as the parameters & complex data type interface should be the same.

[Straticah]

@Christoph-Hart got it, thank you for your time and energy you put into this project. :) I will look into that, didnt work the first time - i am getting an error on compiling a DSP network to a dll. I guess this could be the reason why it did not work in the first place.
