Thanks for building this. Really inspiring and great work.
ClojureScript is such an awesome secret weapon for building web apps. I started building a similar web audio looping app using borkdude's scittle version of ClojureScript. Only once the app had grown substantially, did I move on to proper ClojureScript. The cljs development experience is just awesome.
Sounds like a fun project! I also love that you can start out lightweight in Scittle and then switch to compiled cljs fairly seamlessly if your idea takes off. Such a nice dev experience!
