# Midmid — AI Guitar Hero Chart Generator

Upload a song, get a playable Guitar Hero chart. Powered by a 19M-parameter
masked-prediction transformer trained on thousands of community-charted songs.

**How it works:**
1. Upload an audio file (MP3, FLAC, OGG, WAV)
2. Enter song metadata (title, artist, etc.)
3. Hit Generate — the model analyzes beats, structure, and audio features,
   then predicts note placements for all four difficulty levels
4. Preview the chart in-browser, then download the ready-to-play song package

The output folder drops straight into GHWT:DE's MODS directory.
