# 🥁 SoftChart

Generate a **Taiko no Tatsujin** chart from any song. An 8M-parameter,
plan-conditioned encoder–decoder model turns audio into a playable `.tja`,
with an optional learned planner (song-level structure) and beat-anchoring
model (barline alignment). All models are MIT-licensed and loaded from the
Hugging Face Hub via `from_pretrained`.

- **Generator** ([softchart-generator](https://huggingface.co/JacobLinCool/softchart-generator)) — audio → chart events, with difficulty / density / plan control
- **Planner** ([softchart-planner](https://huggingface.co/JacobLinCool/softchart-planner)) — audio → song-level plan (density envelope, breathing gaps, climax)
- **Beat** ([softchart-beat](https://huggingface.co/JacobLinCool/softchart-beat)) — beat/downbeat detection for barline anchoring

Upload a song, pick a difficulty, and get a preview plus a `.tja` playable in
TJAPlayer3 / OpenTaiko.
