If you are a SpectraLayers user, version 10 has just been released with incremental upgrade pricing depending on your current version - https://www.steinberg.net/spectralayers/

They claim that all the AI features have been updated, and with Unmix that is certainly true. If you have a music track and want to eliminate the vocals, give SL10 a try. My test track is the Fifth Dimension's iconic 'Up. Up and Away' (1967) hit because the vocals are often instrumental in their sound scape particularly the choruses. SL9's Unmix AI was only partially successful in unmixing the vocals from the instrumentals - but SL10 was today absolutely brilliant at unmixing the song - with many more stems than in SL9 - and SL10 successfully identified the vocals which when muted left the instrumental only without any apparent bleed from the vocals. Totally brilliant!

I'm yet to test more, but SL10 really looks like being a giant leap forward.
