Hi everyone, There appears to be an issue with long lists of differently scaled LilyPond notes where they fail to display, but leave no trace of a problem in the log (example below). I'm having difficulty condensing the issue into something simple enough to send to the bug list, but maybe someone with more insight into how LilyPond calculates time intervals internally can help out.
I thought the problem had something to do with using too many different
denominators in the fractions used by the scale syntax. To test this idea out,
I made a script generating notes scaled by multipliers from 1/1 to 1/n (output
for n=30 shown below).
Running my file, LilyPond only manages to render up to note 18. Commenting up
to note 17 (testing to see whether the interval between notes 18 and 19 is at
fault) 18 to 26 render but no further. So from this test I assume there's some
sort of issue with complex time intervals aggregating that stop the notes
rendering after a certain threshold has been reached.
Some input to help take this further and identify exactly what's going on would
be great if anyone is willing!
Thanks,
O.
