Yikes - sounds hard?
I'd have hopes that I could jump into the processor somewhere and get it 
spitting out note names and co-ordinates…. seems like that information must 
exist pretty much in the same place at the same time somewhere in the 
processing chain?
To me, it seems like a really good thing for Lilypond to be able to do, as it 
opens up a bunch of graphical options?
