iZotope RX7 does the same thing. It allows you to pull out the vocals, bass, drums/percussion from a stereo mix and put the extraction into a new track, which can be pieced into a 6 channel file. I have done this with some excellent results over the past few months.
The standard version of RX7 is reasonably priced IMHO.
