I'm not surprised. I read somewhere that Lilypond is used extensively at Hal Leonard publishers. Frankly, after doing a big-band arrangement, I think it's one of the very few systems that can handle large arrangements with ease. I use it nearly every week for my smaller groups...it is exquisitely precise. The only thing I haven't figured out is how to do jazz falls/lip-ups with ease. It's possible, I'm sure, but it seems like it needs the
\jazzGlissUp and
\jazzGlissDown functions to make life easier.
Bravo, developer-folk!
