SAN FRANCISCO, California — Two synth builders, Abraham and Maria, set out to treat Sega Genesis presets as data, not just sounds. The result is DAFMExplorer: an open dataset and web app that lets makers study, search, and play with tens of thousands of Yamaha YM2612/YM3438 patches pulled from classic VGM files.
What is DAFMExplorer?
An openly documented archive and browser for Sega Genesis tones, built for learning and composing.
- A searchable map of more than 93,000 presets extracted from VGM recordings across the 16‑bit library.
- Filter by tag (e.g., “Fantasy Atmospheres,” “Neon Action”), by game, or by composer.
- Audition sounds, load six slots, then download banks for the DAFM SYNTH Genesis or the DefleMask tracker.
What they found
- Seven recurring “sonic realms” emerge when presets are analyzed together.
- Parameter choices—algorithm, feedback, attack rate, detune—show clear habits across studios and titles.
- Side-by-side comparisons make it easy to trace shared DNA between, say, a Streets of Rage bass and a Sonic lead.
Under the hood
- Chips: Yamaha YM2612/YM3438 (six channels, four-operator FM).
- Scope: more than 93,000 tagged presets sourced from a broad Sega Genesis VGM pack.
- Access: a well-documented GitHub repo for local analysis, plus a web app for quick exploration and download.
How to use it
- Open the web app and search by tag, game, or composer (try Masato Nakamura or Mortal Kombat II).
- Pick six presets and audition them together.
- Export a bank for DAFM SYNTH Genesis hardware or import into DefleMask to write your track.
- Clone the GitHub repo to run your own tagging, clustering, or preset studies.
Why it matters to makers
- Shows how composers worked within tight FM constraints—and how those choices shaped the era’s sound.
- Offers ready-made material for education, instrument building, and chiptune composition.
- Invites contributions: new tags, better clustering, hardware tooling, and documentation.
The Editor’s Take: For DIY synth and open-hardware folks, this is the right blend of code, documentation, and playable results. DAFMExplorer turns a scattered archive into something you can study, fork, and load onto real gear—fuel for new instruments, teaching patches, and community research.
