Build log

Built in the open

What's working, what isn't, and why. Updated as development happens.

Why Metamix refuses to place a single cue without a valid Rekordbox beatgrid — and how that protects your library.

A plain-language tour of Metamix's local analysis stack: Apple's native frameworks, local models, and what never leaves the machine.

A 20k-track archive should be an instrument, not a filing cabinet. The story behind Metamix.

Waitlist members see the build log and first look before anyone else.
