There’s another thread here where a few of us tried the splitter in Studio One Pro 7. That test was about isolating the bass track. I got better quality sound on bass with Studio One than Song Master Pro. I still use Song Master Pro regularly to analyze songs I’m transcribing, because it separates the instruments and gives much more information about tempo, key, song sections, and chords.
