RESEED

RESEED is a browser-only remix sketch tool for producers and remixers. Drop in an audio file, inspect its waveform and energy map, then generate three rule-based MIDI seeds that can be exported to a DAW such as Ableton Live.

The MVP is intentionally local-first: no login, no database, no cloud upload, and no external AI API.

Setup

npm install

Development

npm run dev

Open the local URL printed by Vite.

Build

npm run build

Usage

1. Drag an audio file into the upload panel or choose a file from the picker.
2. Confirm the decoded file metadata, waveform, energy map, and section guess.
3. Set BPM, key, scale, intensity, and random seed.
4. Press Generate Seeds.
5. Preview each generated seed in the browser.
6. Export reseed_chords_<key>_<bpm>.mid, reseed_bass_<key>_<bpm>.mid, or reseed_lead_<key>_<bpm>.mid.

MVP Features

• Audio upload via drag-and-drop and file picker.
• Browser decoding with AudioContext.decodeAudioData.
• Canvas waveform from a mono peak representation.
• Audio playback with play, pause, stop, seek, and waveform playhead.
• RMS energy analysis with smoothing and highlighted high-energy bars.
• BPM-based 16-bar section candidates.
• Key, scale, intensity, and random seed controls.
• Rule-based MIDI generation for chords, bass, and lead/arp fragments.
• Tone.js preview playback with one seed playing at a time.
• Browser-generated Standard MIDI File export.

• Tone.js
• lucide-react
• clsx

Browser-Only Notes

Audio files are decoded and analyzed in the browser. RESEED does not upload audio, call a backend API, store projects in a database, or use an AI service.

GitHub Pages

The Vite config uses base: "./" so the static build can run from GitHub Pages paths. A GitHub Actions workflow is included at .github/workflows/deploy.yml.

To publish:

1. Push this branch to GitHub.
2. In repository settings, enable Pages with GitHub Actions as the source.
3. Run the deploy workflow or merge the branch into the default branch.
