Steinberg SpectraLayers 10 pro (plugin and stand alone)
I just found the Stenberg SpectraLayers plugin for extracting stems directly in the DAW (I am testing it in StudioOne)
Very handy to have it directly in the DAW and to be able to drag and drop the stems into the tracks as needed. But quite expensive. I currently playing along with the 30 days trail full pro version.
It seems that one need the pro version to extract all stems (vocal, drums, guitar, piano, bass, other) the elements version seems to be limited to vocals only.
First impression is that the quality is higher than the other stem extractors I have tried.
Very fun to play around with, but it have to wait for now, a bit too expensive at the moment.
