I should also have mentioned that there was a thread with a title like this on rec.music.theory not long ago. I put pointers to the actual pdf's being discussed on my blog <http://www.laymusic.org/cgi-bin/blosxom.cgi/2005/08/14#050814-comparison>. The programs compared don't include any of the ABC family, unless you count lilypond, but there are some interesting points made. -- Laura (mailto:lconrad@xxxxxxxxxxxx , http://www.laymusic.org/ ) (617) 661-8097 fax: (501) 641-5011 233 Broadway, Cambridge, MA 02139
