> Hi all,

> I'm looking for a tool that can analyse an MP3 file, and write out a 
> polyphonic MIDI file - basically so I can have the sheet music. Can

> 
> Although this is a Linux list, I don't care what platform the tool runs 
> on, since I will only use it once and then go away happy with my MIDI 
> file :)

> So far I only found a demo Windows program called intelliScore 
> Polyphonic Demo. It's limited to the first 15 seconds but unfortunately 
> it made such a terrible job that I don't feel inclined to purchase the 
> full version.

> The MP3 in question is "Vevey (Revisited)" by Yes, from their 1977 album 
> "Going for the One". It's a simply constructed piece of music but the 
> organ chords are really confusing me. I've tried to go through it and 
> notate it manually, but I seem to be incapable of picking the notes out 
> of the chords. Rick Wakeman is clearly a genius :)
