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.

https://fretool.dev-zoo.net (Fretboard visualizer)

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

https://harptool.dev-zoo.net (Harmonica helper)
