Procedural Music Workstation in the Browser
As a side project for a hockey manager game, I created a small audio tracker, "HM Tracker," which was used to make the game's music. It is a browser-based tracker-style music workstation. All sound is procedurally generated from oscillators - no samples, no plugins. The UI lets you edit patterns on a step grid, pick instruments and chords, then export as a standalone JS music engine or WAV file. Built with vanilla JS and the Web Audio API (best experienced on a desktop browser). Made in the '90s demoscene spirit (at least the looks, anyway). Would love any feedback!

I've been tinkering with a browser-based rhythm game creation tool. The pitch is simple: AI makes the music, Essentia.js figures out the beats, and you write the game logic in JS. Demo: https://rhythm-seodang-web.vercel.app/ The problem I wanted to solve: most rhythm game workflows are heavy. Proprietary editors, manual charting, fixed gameplay patterns, desktop-only. I wanted something where you could just... open a browser tab and start messing around. How it works: - Music comes from AI services (Suno/Udio). No user uploads, no copyright headaches. - Essentia.js (WASM…
