Reverse Engineering Pioneer Pro DJ Link with Claude Code
How we paired a human with a CDJ-3000 and Claude Code to reverse engineer Pioneer's Pro DJ Link protocol — capture-first, fixture-replay tested, and reliable.
The deadca7 CLI is JSON-first over the catalog API: stable exit codes, a JSON error envelope on stderr, and a configurable base URL. Everything you can do by hand, you can script — and so can an agent.
Every track in deadca7 shows a three-band low/mid/high waveform you click to play, pause, and seek — streamed straight from the source, generated once with ffmpeg and cached.
Paste an archive.org URL into the command palette, preview the collection, and build it — while imports run in the background, crash-safe and resumable, and you keep browsing and playing.
One Library, Many Sources
Why deadca7 exists: your crate should be yours to take anywhere. One library that unifies every source, exportable to your gear and not trapped in any DJ software ecosystem.
