I presume this is not possible - would likt to produce a score from the music (via NWC)
I'm not sure what you mean by "MP". Can you elaborate? Is that an abbreviation for another music application?
Maybe he means an MP3 file in which case he is correct - can't be done... (yeah, yeah, I know there're products that claim they can, but they really can't and in anycase NWC is NOT one of them)
