Notes being dropped during playback and mp3 export with MuseSounds

[blackears]

Describe the bug
When I use the Grand Piano from MuseSounds to play back this piece, I am unable to hear some of the notes (the eighth note in measure 1, all the Ds in m2 and the half note in m4). When I use MS Basic, the notes are all heard.

This also affects export to mp3 where these notes are also being dropped.

All notes should be heard, particularly when exported to mp3.

Platform information
Windows 10

That's because the note overlaps with a note on the other staff. So, a duplicate of #13853. That was closed because it's mostly fixed for MS Baisc, but definitely still a very serious problme for Muse Sounds.

I think I'll close this in favour of #15306, which describes the issue more specifically (namely that it relates to overlapping notes in different staves).
Thanks for reporting!
