Interesting, need to try this out.
This is a fun tool. I’ve made some tracks in Renoise, exported to wav, then ran them through Spleeter. The results are often interesting. Little audio artifacts, strange mingling of instruments. These then can become sample material for further tracks.
FWIW, I’ve installed it on Windows 10 using the Windows linux subsystem. Works great.
There is an online version of this here
