I checked the result against my part (trombone 3) In the 3rd pianoconcerto from Rachmaninoff, and I get the following result: Rach3-1: 0 Rach3-2: 9 Rach3-3: 185 Which is correct... The effect of this is visualized here: http://www.youtube.com/watch?feature=player_embedded&v=6dI-S77-jIY (Of course that's compressed in 4 minutes - the whole concerto lasts around 40 minutes) I've also learned that we entered 130K notes in LP for the SCORA launch concert , of which 30K alone are for the piano part for Rach3. There's also close to 700 staff up/down transitions in that score. Rachmaninoff goes in public domain on January 1st. Maybe I should clean up the sources a bit and put them on mutopia. There's a discussion here on having examples of what LilyPond can do. Well, that's an example. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
