      @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

        @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 <: _,_;

          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? ;)

            @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.

                @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?

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

                      @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.

                        This doc is slightly outdated as there have been many additions to SNEX. Basically SNEX is C++ minus all stuff that you don't need for DSP:

                        • String operations (there's even not a text data type)
                        • File I/O or other OS stuff
                        • inheritance and constructor / destructors of objects
                        • pointer syntax, so any reference to memory is being done via the reference operator &. I chose to do this because it's much harder to create a null reference using this approach which makes the language a bit more stable (especially in a prototyping context).

                        However I would say that it's halfway between HiseScript and C++. Sure you have to use proper typing (in HiseScript / Javascript it doesn't matter if a number is a integer or floating point number, but since SNEX directly creates machine code, it needs strict typing to emit the correct assembly.

                        var x = 12 + 0.5; // OK in HiseScript
                        float x = 12 + 0.5; // type mismatch, will print a warning and cast implicitely to float.
                        

                        The example that David posted is trivially portable to HiseScript:

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

                        The Math class is almost 100% identical in SNEX and HiseScript so this eases the pain a bit :)
                        About the auto&: In SNEX you have the same range-based for loop as in Javascript (give it an array and it will iterate from the start to the end). However since it's strictly typed, you need to declare the element type of the block array that you want to iterate. auto is just a way of letting the compiler figure out the type itself, so it removes redundancy:

                        auto x = 12; // x is an int;
                        int x = 12;  // same statement but you have to figure out the type yourself.
                        
                        auto y = 12.0f; // x is a float (the f postfix indicates single precision)
                        

                        Now the & operator means "reference to" and tells the compiler to operate on the oringal data itself. Outside a loop it can be used like this:

                        int x = 126;
                        auto& refX = x;
                        
                        refX = 100; // x is also 100 now
                        
                        auto noRef = x; // omit the & makes a copy
                        noRef = 9000; // is still 100
                        

                        Now if you write the loop without the & like this:

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

                        it is still valid C++ / SNEX syntax, but it will not have an effect because the sample variable will not point to the actual element in the array, but a copy of the value (like noRef in the example above), so the sine wave is being rendered into nirvana.

                          @Christoph-Hart Thanks you!!!!!

                          well! I guess I started learning SNEX now!
                          I'm on January Scriptnode. Should I find a new working commit ? (MacOS)

                              Yeah I can‘t recommend diving into SNEX at the moment (especially on macOS), I‘m afraid you need to wait a few more weeks.

                                @Christoph-Hart @d-healey already diving into (yeah I'm that anxious) . I need to solve a DSP thingy some how... so I will adapt it later to the new SNEX I guess.

                                I'm sketching in Faust, and trying to reproduce that on SNEX....
