# marimba platter

Whistlegraph-coded pop tracks built bottom-up from the modal-additive
marimba synth at `synths/marimba.mjs`. All share the same DNA: a
syllabic chant the mallet voice hums but never speaks, layered voices
named per section, a pop-mastered mp3 + a colored-pencil + gouache
cover brief.

Score doc is the `.np`. Cover prompt is the `.illy.txt`. Audio is in
`out/<name>.mp3`. Render any track:

```bash
node pop/marimba/bin/render-<name>.mjs            # default path
node pop/marimba/bin/render-<name>.mjs --out ~/x.mp3
```

## next moves

- Cover gens: `bin/gen-illy.mjs` per track (one-shot, $-budgeted).
- Storyline visualizer (insta-story 9:16): see `bin/preview-score.mjs`
  + `bin/gen-sections.mjs` — works on any track with a `.struct.json`.
- DistroKid: follow the marimbaba path documented in
  [../RELEASES.md](../RELEASES.md). Per-track master chain is already
  embedded in each `render-<name>.mjs`.
