This worked very nicely - thank you!

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:

(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.
