Beats per minute interpreted incorrectly in certain MIDI files detected as "human performance"
Load the MIDI file "Blowing In The Wind" - this has a beats per minute (BPM) of 135 and you will see that it appears in MuseScore as 144.
Load the other MIDI file "Retimed In the Wind" - this is essentially the same music but all the durations and timings have been scaled by 75/135 to give a BPM of 75. It looks very different to the first one but plays exactly the same if you choose to play it. This one has a BPM of 75 but again in MuseScore it shows as 144.
If I load these same files into any other scoring program (for example QuickScore Elite) they both show the correct BPMs of 135 and 75 respectively.
So MuseScore is getting something wrong here. Each of these files only has one Tempo Message in it. In the first file it is close to the beginning, in the second file it is the first MIDI Message in the file.
