Hi!

I've another basic noob question

So for a module manufacturer like Vult for example, they have a large range of modules in the VM store that reflects the range in VCV Rack. I know they use their own Vult language that transpiles to a range of languages, C++, JavaScript etc, but I see no Java option.

Would they have used the C++ wrapped using JNI, or ported everything to Java by hand? Just trying to get the lay of the land in this domain

Cheers

I think you'd have to ask Vult about specifics, since CA only has access to byte-code compiled modules, not the actual internals. He might or might not be willing to share the information, given that it's his stock in trade.

There's an intermediate "Vult" DSP language that has compilation targets of C++ or Java -- https://modlfo.github.io/vult/

I tried this out a few months back, and if I recall, the docs for exporting Java code aren't quite correct, but I did get it to work after sifting through the source a bit and using the errors messages to adjust things.

Thanks @UrbanCyborg. Strange I can't see any reference to Java (on JavaScript) in the docs, perhaps I'm overlooking something?

I was more interested in whether you'd have to port your existing dsp code into Java (more work depending on complexity), or whether you could leverage importing an interface to C/C++ code (less work)?
