Hi Lilyponders,

Following my request to update and debug the midi2ly utility:

I'm also a user of Mup, a program similar to Lilypond but shareware, and 
slightly less advanced. ( Which reminds me: whatever happened to mup2ly 
? Can't find it anywhere anymore. )

In the mup-users mailing list was a discussion 
about mtm ("midi to mup"), a utility comparable with midi2ly. The 
discussion was about: how to determine when to use sharps or flats ?
There is more to it then just determining the key and scale. Especially 
minor scales and late 19th century romantic music can be problematic. 
Not to mention 20th/21st century music.

A snippet from the discussion from the mup mailing list:

After having had a short look at David Meredith's paper I realize that I
need to revise my doubt on usable algorithms for calculating sharps and


Could be interesting stuff to read for Lilypond / midi2ly developers
