1. Add MP3 files
Use the sample MP3s you supplied, or any local MP3. The browser decodes and analyzes the audio directly.
2. Analysis settings
Phase 10 preserves beat/form, stems, MIDI-like phrase extraction, the musical quality gate, Phase 8 audition/grid editing, and Phase 9 library manifests, then adds direct ArrangeAI Beat Architect project handoff.
Export current previewed ArrangeAI JSON. The file name begins IMPORT_THIS_IN_ARRANGEAI_<source_mp3_name>_phase10_5_ and is bound to that source file's name plus identity/feature hash. Do not use the batch pack, manifest, website pack, or handoff pack for the normal importer.
3. Optional stem-aware workflow
Add user-supplied stems for the selected MP3 arrangement. Phase 10 keeps the optional stem workflow from Phase 4/5 and carries stem role hints through the audition/grid editor, quality gate, import bridge, and direct ArrangeAI project handoff so ArrangeAI receives lane-safe metadata.
4. Results
Each completed item can be exported individually. The batch pack stores all analyzed arrangements in one JSON file.
5. Review, audition, and pattern-grid editor
Phase 10 lets you review guessed tempo, key/scale, downbeat confidence, adaptive form, motifs, cadences, stems, phrase events, audition playback, pattern-grid edits, quality-gate repairs, import-bridge validation, website-library manifest metadata, and direct ArrangeAI handoff metadata before export.
6. Selected JSON preview
Preview is truncated for speed. Use Export selected JSON or Export direct ArrangeAI project for the full file.
