Yep, that's it. Modified ob-lilypond.el and recompiled it. Timidity
works as helper, couldn't get vlc to work. Maybe the file ending
should be modifiable via org-babel-lilypond-commands as well, or make
ob-lilypond.el look for *.mid or *.midi. I'm pretty confident *.mid is
the default setting for lilypond on win, and not my doing.
