I found Ultimate Vocal Remover does a good job with Stem Separation.
It is FREE. But has a learning curve. One can choose from various models, even Combine them. If you have a AI capable Graphics Card, the calculation time would reduce. Some models allow for 7 different instruments.
Studio One 7 has a Stem separation funktion build in now. Most cases I just use that if I just need a Karaoke track with Voice removed. Works fine for that purpose, only in rare cases I employ UVR.
