A Sublime Text package that turns code into music

Claude Code wrote Synesthete, a Sublime Text package that composes music from the code being edited and from changes Claude makes.

The full story

Synesthete composes music from code line by line: deeper-indented lines play higher, each line's text picks the note, function definitions bring in the bass and broken lines sound dissonant. Code quality picks the instruments, from a harp for clean code to a singing saw for cursed code. In project mode, every file Claude Code changes plays an accent.

Claude Code wrote all of it in one long session while the poster listened and gave feedback. Its first synthesized sounds were "like a broken TV", so it switched to public-domain orchestral samples, and it tuned project mode by making good and bad changes to a test repo.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
