This example requires you to install some tool for rust.
cargo install sfz
cargo install wasm-bindget
cargo install wasm-pack
rustup toolchain install wasm32-unknown-unknown
Run: run.sh
sfz will serve the files for you and you will acces them on 127.0.0.1:5000/html/index.html
THIS IS A VERY SIMPLE EXAMPLE. Only to get you started to figure out on your own what can be done.
