retro-sync — Getting Started

What is this?

A music publishing platform that encodes public domain music into steganographic NFT tiles. Browse the catalog, play MIDIs decoded from PNG images, register works with collection societies.

Quick Start (5 minutes)

1. Browse the catalog

Visit: https://solana.solfunmeme.com/retro-sync/menu.html

2. Play music from tiles

Click any collection → tiles load → click "🎵 Reconstruct" → play individual tracks

3. Add a new collection 

git clone https://github.com/meta-introspector/retro-sync
cd retro-sync
nix develop

# Search for any composer in the MIDI dataset
bash scripts/onboard.sh "chopin nocturne" -n 15

# Build stego tiles (needs pypng)
nix-shell -p python3Packages.pypng imagemagick --run \
  "bash scripts/stego-build.sh projects/chopin-nocturne"

# Generate catalog entry
python3 scripts/catalog-gen.py
python3 scripts/artist-ids.py

# Export CWR for collection societies
python3 scripts/export-cwr.py

4. Deploy 

# To local web server
bash scripts/deploy-space.sh projects/chopin-nocturne

# To HuggingFace
bash scripts/publish-catalog.sh

Architecture 

MIDI files
  → onboard.sh (search + project setup)
  → midi2svg.sh (lilypond sheet music SVGs)
  → stego-build.sh (embed MIDIs in PNG tiles)
  → catalog-gen.py (WorkRegistration JSON)
  → artist-ids.py (Wikidata QID → RS-ID + ISNI)
  → export-cwr.py (CWR 2.2 for societies)
  → publish-catalog.sh (HuggingFace)
