Nice that you have highlighted your post again.

I wanted to use the video to show the whole process from a more complex piece of music in Musescore to the transposable sheet in mobilesheets. In this respect, not everything was clear to me in your posts. However, I cannot publish the whole piece of music here for copyright reasons.

Secondly, I wanted to visualize the problems that occur, especially when transposing.

Here is the text form with zipped files:

• Hay_Burner_Test.mscz is the massively reduced source file in musescore 3.6.2
  
• Hay_Burner_Test.mxl is the compressed MusicXML file exported from Musescore
  
• Hay_Burner_Test.abc is the ABC file created with the freeware tool EasyABC
  
• Hay_Burner_Test.pro is the ChordPro file extended by {start_of_abc} and {end_of_abc} for importing to mobilesheets and renamed to ".pro"
  
• Hay_Burner_Test.pdf shows the additional notes that appear when transposing in semitone steps in musescore
  

If you transpose the mxl- or abc-file in Michael Eskin's ABC tool, as shown in the video, the wrong additional notes do not appear. For me, this is a proof that the problem lies in mobilesheets.
