- This fix requires a redownload of the launcher.

full changelog ↓// features
- Pick the instruments you want and that's what you get. Each uses my preferred splitting model either for quality or speed, but you're able to easily set alternate model at any time.
- Drum-kit splitting into kick / snare / toms / cymbals (choice of 4/5/6-pieces).
- Routes to the best open models (BS-RoFormer, DrumSep, Demucs) and handles all downloads.
- Automatically sets up GPU acceleration if you have the hardware for it.
- Useable as an interactive TUI for normies or one-line CLI for scripting.
- Mac / Windows / Linux
// changelog
0.9.7 2026-07-11
- Split levels now match the source, so the stems sum back to the original mix instead of coming out quieter.
- The residual now lines up correctly on sources that aren't already 44.1kHz.
- The residual now supports the same input formats as the splits, instead of failing on some files.
0.9.6 2026-07-02
- Clearer drum splitting: the stem list no longer greys out, and the drum-kit options (Split, and Song vs Drum stem input) are now grouped and only active when Drums is selected.
0.9.5 2026-07-02
- Fixed a bug where using "Drum stem" mode could lock the stem picker after restarting the app.
0.9.4 2026-06-29
- RTX 50-series GPUs now work.
- New Compute setting to switch between GPU and CPU.
- Output settings and per-instrument model picks now persist between launches.
