Bad notes length (shortened) when exporting midiFile using museScore
1) Write a score with some half and whole notes
2) export the score as a midiFile
3) check the midifile, and note's durations
Exported as midiFile and imported in Ableton Live,
Every note has been shortened !...
(An exported whole has a duration of 3.75 instead of 4 quarters,
same for the half notes)
The same score using Sibelius, exported as midiFile and imported in Ableton Live
Note's length are now correct (that means that the problem doesn't come from Ableton Live.
Importing the museScore midifile in music21 monitors bad note lengths as well.
Notice that it's the default behavior of museScore. I didn't check / uncheck any museScore option.
It can be easily reproduced (and I didn't find any workaround).
It is a major issue. I cannot be confident in museScore midifile output as it doesn't reflect the written score.
With the bad instrument name formatting bug, it makes museScore almost unusable to work with music21, for example...
