Re:Ask HN: What are you working on? (September 2025) on Tuesday September 30, 2025 @02:48AM (#45422642)

I'm working on a bunch of small tools for musicians. I want to simplify complex musical concepts by giving visual feedback and minimal UI. All modular components built with pure JavaScript.

Here are some of my first results (free PWA):

https://atoy.dev-zoo.net (real time audio slowdown and looper)
