# bitwrap.io

> Music apps for people who want to play, not produce. Tracks are generated by rules, not AI:
> seeded randomness, Euclidean rhythms, music-theory rules and hand-weighted Markov chains, with
> the arrangement executed as a Petri net. The same genre and seed give the same track every
> time, offline, and a content-addressed share link (a CID) rebuilds the track bit for bit.

This page is the index. Each app below serves its own llms.txt with the details.

## Apps

- [beats](https://beats.bitwrap.io/): browser beat sequencer whose arrangement is a Petri net.
  Generate a track by genre and seed, perform macros live, share a content-addressed render.

- [ontology](https://ontology.bitwrap.io/): the music-genre vocabulary the generator works from
  (genres with tempo, scale, groove, Euclidean rhythms, instruments, chord progressions; song
  structures; engine concepts linked to the pflow ontology). CC0 1.0.
