 **Stemify** is the separator. Drop files on the window and each one is separated with your last-used model and device. You get a lane per stem with a waveform, solo, mute, gain and export (everything, one stem, or the current mix, as WAV, FLAC or MP3). Separation runs in its own process, results are cached, and it works on AMD, NVIDIA and CPU.
 
-**Stemify Player** is your Plex library and its stems, dressed up as Microsoft Excel 2016. Sheets are your library, the zoom slider is master volume, Cell Styles are mix presets, and Undo/Redo skip songs. It reports plays to Plex, supports media keys and MPRIS, and remembers your queue and mix. More in [`stemify/player/README.md`](stemify/player/README.md).
