I have the WebAssembly music project at https://github.com/petersalomonsen/javascriptmusic and the main motivation for creating this live-coding music platform is to create music. I've also ported libgit2 to emscripten so that you can have a full offline-capable git client in the browser. Check out https://github.com/petersalomonsen/wasm-git

I'm also a hobby composer and pianist, and recently go into the concept of creating music using code. I've also always wanted an easily accessible and cross-platform tool for creating music, and so the web-browser was an obvious choice, using WebAssembly to deliver the required performance for realtime sound synthesis. And also since music is written in code, having a git client and offline capable file system in the browser is essential.

See my talk from WebAssembly summit 2020, and also other videos demonstrating live coding music.

Even though wasm-music and wasm-git are my hobby projects, I'd like to invest more into equipment and hosting. Being sponsored would also be a great acknowledgment of what I'm creating here.
