The following works for me & my girlfriend who is anything

alpha: there is voicing analysis, I think it kinda works for up to
2 voices per staff, and SharpEye cannot handle > 2 voices per staff
anyway.

My filter is in http://www.cs.vu.nl/~rutger/software/niff2ly-0.2c.tgz
in source form. It generates lilypond 1.(6,8,..). Methinks it is easy
to upgrade it to Lily 2.
If anybody wants me to upgrade it to generate Lily 2, let me know.
If anybody needs a cygwin or RedHat binary, let me know.
