Hi David,

I do know a bit of programming myself, but LISP and its dialects are absolutely beyond me - it is one of those languages that still look completely inaccessible to me, which is a pity since I'd really love to help by coding.

I hit a problem with << >> (SimultaneousMusic), but I have > your request in mind This is indeed tricky, I didn't think about this situation before. Here is an example /without/ any rhythmical complexities (with those, things can turn into nightmares very quickly, since ottavation affects the whole staff...): <http://lilypond.1069038.n5.nabble.com/file/n167757/53.png> (this example above is a bit exaggerated, but think of instruments that have a nice range and are traditionally notated in one single staff, such as a xylophone). If I may suggest something, what about simply ignoring places where two or more voices occur and outputting an error message to the user telling the lines that are problematic? This way, one can find the problem and solve it by: \ottavation #'(4 . 7) #'(-4 . -7) { \musicPartA } \musicPartB \ottavation #'(4 . 7) #'(-4 . -7) { \musicPartC } where \musicPartB would be the passage that needs manual tweaking. I think a lot of these decisions are easy to take by a human but very difficult to generalize (I have been myself working on a code (not in Scheme ;) ) to decide between flat and sharp accidentals in atonal music, but there are situation that makes the computer go nuts (or makes the code increasingly complex and long), where a human can spot right away what is the best solution, or the least worse alternative).
