Cardinal on the web randomly got some attention via
https://news.ycombinator.com/item?id=35794758
So I wonder how many people out there still do not know this is a thing...
The full Cardinal (basically a more free version of VCV Rack, with all modules built-in) running directly on a web browser at https://cardinal.kx.studio/
I recently updated it so that on browsers that dont support wasm-simd (webkit-based ones like Safari) will load a slower but still compatible variant.
So in theory it works under iOS, didnt test.
