Show HN: A techno machine in one HTML file, with verifiable renders
Points and comments are a snapshot, not live.
A modular techno machine built as a single HTML file with verifiable offline renders.
RACK-02 is a modular techno machine in one HTML file. It includes a clock with swing, humanization, and ducking; scenes for arranging patterns; modules for kick, bassline, hats, vox with live input, and grain resampling. Features include a patchbay for modulation, automation lanes, MIDI out, and offline bounce for sample-exact, no-dropout export. The interface is keyboard-controllable and works locally as a standalone single-page app.
What commenters are saying
Commenters were overwhelmingly positive, praising the single-file, zero-dependency design and portability. Several noted it works locally after download and on iOS. Some questioned the need for "verifiable renders" and criticized the font choice as resembling LLM output. A few commenters called it "vibe-coded" and lacking in musical character compared to older tools like Rebirth. One user requested higher BPM for DnB.
