| # Hendrix |
|
|
| Hear a recording, see its notes, and turn it into MIDI. |
|
|
| Explore 14 music clips: full-band mixes, guitar performances, electronic music, |
| rock, folk, pop, hip-hop, and instrumental tracks. Each clip comes with prepared |
| Hendrix predictions, so you can listen and download MIDI right away. Press play |
| and drag the **Original ↔ MIDI** slider to blend the recording with its |
| transcription. Seek through the waveform or mute individual instrument parts. |
| MIDI plays with sampled instruments from GeneralUser GS by S. Christian Collins. |
|
|
| Choose a file or record with your microphone to transcribe your own audio. |
| Decoding and inference run on your device; the app does not upload your recording. |
| The first live transcription downloads 195.3 MB of model graphs and the browser |
| runtime. WebGPU is preferred, with a WebAssembly CPU fallback. Start with two |
| seconds on slower devices. The example library needs no model download. |
|
|
| [Open the app directly](https://jackboyla-hendrix.static.hf.space/) for the full |
| listening view. Microphone access depends on browser permissions. Predictions |
| can miss notes, choose the wrong instrument, or give poor note endings. |
|
|
| The example audio comes from Free Music Archive, GuitarSet, and Slakh2100 under |
| CC BY licenses. Clips are cropped to at most 12 seconds and converted to mono |
| 16 kHz audio. [Full creator, source, license, and crop credits](https://huggingface.co/spaces/jackboyla/hendrix/blob/main/examples/CREDITS.md) |
| accompany the clips. Prepared notes come from the fixed Hendrix model, not |
| reference annotations. [GeneralUser GS license](https://huggingface.co/spaces/jackboyla/hendrix/blob/main/soundfonts/LICENSE.txt). |
|
|
| The 46.5M-parameter model derives from YPTF-MoE+Multi. |
| `models/fp32/manifest.json` records the source checkpoint and checked FP32 graph |
| hashes. `deployment.json` records the app source and file hashes. This static |
| Space needs no server-side inference or GPU. |
|
|
| [Source, methods, results, and deployment commands](https://github.com/jackboyla/hendrix) |
|
|
| The `source/` directory contains the exact app source and prepared audio assets |
| used for this deployment. To rebuild and publish from that snapshot: |
|
|
| ```bash |
| cd source |
| npx --yes pnpm@10.20.0 --dir demo/web install --frozen-lockfile |
| hf auth login |
| uv run --no-project --with huggingface_hub==0.36.2 python \ |
| scripts/deploy_huggingface_space.py --graph-dir ../models/fp32 --upload |
| ``` |
|
|
| Omit `--upload` to build and check a local package. Each run prints the staging |
| directory. The script checks the model and example hashes and refuses to change |
| an existing Space's visibility or SDK. |
