Faust is here...

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:

Design the effects in scriptnode
Compile them to C++ effects
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.

@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.

Yellow is not an error, even if the warning is about a function that has error in its name :)

Codegenerierung ist abgeschlossen.

That's german for "Everything OK".

Straticah

@Christoph-Hart okay, good to know :)

Sawer

@Christoph-Hart
Ok, do I need to compile the whole scriptnode into a custom-project c++ class or only the faust node?

Thanks

Christoph Hart

@Sawer The whole scriptnode patch, but you can create a subpatch that only contains the faust node if you want to use a interpreted scriptnode patch in your exported plugin.

Sawer

@Christoph-Hart
Thanks so much.

So I'm currently trying to export the full effect as a DLL and here are the issues facing:

The autogenerated Juce file comes without all the paths and flags to activate Faust.
.
Is there a way to automate this process?
I solved this issue by setting all the paths and flags to make it work. I opened Xcode to build the file and the DSP file is not in the expected folder:

The file is saved in _PROJECT/DspNetworks/Code library, but the program expects it to be in _PROJECT/DspNetworks/ThirdParty/Src. Is the program supposed to fetch the file from the Code library and transfer it to src? Or, should I do it every time?
I solved the issue by copying and pasting the file to src. I again saved the .juicer file and opened xcode to see if it compiles, unfortunately, I get a lot of syntax-compiling errors related to the whole scriptnode effect itself (script_fx1.h).
.

That's how far I've got... Wondering if you have any idea of all of this happening and if @Straticah got the same issues as well.

Thanks

Christoph Hart

You've got it wrong somewhere at the beginning, it is supposed to be a fully automated process without having to move files around or add custom flags.

I'll check again here on my Macbook if something broke the export along the way.

Sawer

@Christoph-Hart Ok I Will also try again on my end to see if the project settings are on point

Christoph Hart

Nope, works here perfectly.

Have you copied the faust files into the HISE tools/faust folder? I changed the build configuration on macOS so that you don't need to fiddle around with compiler flags anymore and this might have broken the export if you're still using a faust path at another location. Here's the instruction list:

HISE/tools/faust at develop · christophhart/HISE

@Christoph-Hart You are right:

I only have the fakelib..

Sawer

@Christoph-Hart If I am right I've just copied and pasted the folders from the main Faust folder into tools/faust. Hope this works

Christoph Hart

@Sawer Have you installed the x64 version of Faust? You must not copy the ARM binaries in there if you're on a M1 machine.

Sawer

@Christoph-Hart The copying and pasting works perfectly. Now I have the effect working in the Hardcodedmaster FX.

Thank you so much Christoph!

Christoph Hart

@Sawer Alright. FYI I've also added a new post with the current updated build instructions that will hopefully clear things up.

@Christoph-Hart said in Faust is here...:

support for MIDI and polyphony (at the moment it's only possible to use Faust for audio effects)

I can't get Faust MIDI instrument to be polyphonic. I'm adding in into a ScriptFX module. Within a Midi chain. How do I enable polyphony?
