This sounds like a good idea. I did not look at that part of the  
code, but is that functionality cross-platform compatible? Does it  
work on Solaris, BSD, Linux, Mac OS X and Windows?

I'm having trouble myself with some defun's that have midi in their  
name (like (defun LilyPond-string-current-midi () ). In the intro, it  
says that lilypond-mode.el has support for:
<copy src="lilypond-mode.el">
;;;;    * Add PS-compilation, PS-viewing and MIDI-play (29th Aug 2001)
;;;;    * Keyboard shortcuts (12th Sep 2001)
;;;;    * Inserting tags, inspired on sgml-mode (11th Oct 2001)
;;;;    * Autocompletion & Info (23rd Nov 2002)
</copy>

I'm hoping that I'm not stepping on any toes here, but it seems to me  
that in a true unix tradition, lilypond-mode should do only one thing  
and do it good and that is helping with the editing of .ly files. So  
could we please leave the PS-compilation, PS-viewing and MIDI-play to  
more appropriate emacs editting modes?
I'm the maintainer of three major modes (with minor usage and all  
only for gnu emacs), so I do know a bit about emacs modes. It seems  
to me that things can be accomplished in a more straightforward way.  
Just three days ago I dabbled with the idea of writing my own  
lilypond-mode.el that would only do font-locking, auto-indentation  
and compiling .ly files. It's just that I'm too pressed for time  
that's holding me back. Aber wenn Ich dir helfen kann, dann sag's mir  
bitte.
