Perhaps I was dreaming, but I thought I read somewhere (but can't find the place now!) that with PowerTracks a user can read an existing polyphonic WAV file and extract a reasonable approximation of the melody and chords.

If that is correct, I'm ready to drop a significant portion of this month's Social Security check to get that kind of software! Manual transcription of very old gospel music is a passion as part of my retirement hobby and it is painful most of the time because the renditions are often not very precise musically (rhythm especially).

TIA.
