Hi Anders,
Well you did put teh finger on the REAL issue, why Musicxml standard ain’t one…
THEORETICALLY, you could put whatever you want such as ratios. (I know ratios are not computer friendly).
However, putting integers is very constraining because, it’s parser dependent !! :
i.e Finale has a different duration/division base than Sibelius, and let’s not talk about muscxml2ly
which apparently doen’t want to work ever… (it didn’t still back then UNFORTUNATELY!).
So unless doing 2 to 3 or many type of exports for each software, (which i think is hasardous, since they can change anytime their own specifiacations), or rely on another strategy.
ANd let me explain to you why the ratios. : because it allows us to use any rhytyhm imaginable figure which should be correctly and theoreticaly displayed.
Now if the users want a specific musicxml export for each of their beloved note engraving software, well , this is possible but mostly non elegant.
I succeded for the example above in importing it in Finale 2010 but NOT in 2012… that’s because teh guys there changed the spec…
You see what i mean…
Best
K
