Looks interesting, will we have access to it from within the standard MIDI callbacks or will it live in its own processor module?

[Christoph Hart]

Yes, you can call it like any other function in your script. Maybe I'll add an option to autoforward the MIDI callbacks directly to a given SNEX class so it reduces the (small) overhead of calling into HiseScript altogether, but this works already:

snex.struct MyProcessor
{
    int isFastNote()
    {
        // A small selection of API calls will be available in SNEX
        double thisTime = Engine.getUptime();
        int isFastNote = (thisTime - lastTime) < 0.5;
        lastTime = thisTime;
        return isFastNote;
    }

    double lastTime = 0.0;
};

const var obj = snex.make<MyProcessor>();

function onNoteOn()
{
    if(obj.isFastNote())
        Console.print("Fast Note");
}

snex.struct MyClass
{
    // span<T, Size> is a fixed sized array
    span<float, 44100> data;

    void process()
    {
        // a range-based loop over the entire array
        // (the & means "reference to" so you operate directly on the array)
        for(auto& s: data)
            s = Math.max(s > 0.5 ? (Math.random() + Math.sin(s)) : 2.0f, 50.0f);
    }
};

So this is saturation by iterating over the 44100 sample buffer? I take it this does nothing to the audio until you call obj.process()?

Either way DSP like this is

Sounds great

Oops I think it's actually just a random number generator for performance comparison.

How would we apply an algo to a sample/block/buffer with this? AKA teach me how to DSP so I can forever leave JUCE in my rearview

So cool! Can’t wait to try it

@Christoph-Hart Anxious to to get this working, but it does not compiles on Mac :(

snex_ArrayTypes.h

[Christoph Hart]

Yeah it‘s not commited yet, so you need a bit more patients (sooooon ;)

@Christoph-Hart ok, just copy paste this
