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:

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