Non-tonal percussion MusicXML import/export improvement

[zacjansheski]

Your idea

Non-tonal percussion import/export via MusicXML should be improved upon. Very simple parts have odd behaviors when importing and exporting within MuseScore Importing MusicXML parts from other programs yields even worse results.

Problem to be solved

Make a score with a snare drum Export to MusicXML Open in MuseScore, it is now plays as a string instrument https://github.com/musescore/MuseScore/assets/69917893/41039bad-178b-4b3c-a612-a384b25fb886

Could the program recognize what is a non-tonal percussion instrument and give the user a chance to assign it to a percussion instrument / load a drumset file?

Looking into going from Sibelius to MuseScore.

Very different appearance, but at least it plays as bongos. However, there is no differentiation between normal noteheads and x noteheads

Sibelius

MuseScore

Snare test.zip

Another example why you should never use the Sibelius Direct export, which is exceptionally bad. There is no information in the file about which MIDI note should actually be played. The basic import/export issue in MuseScore has (apart from some minor flaws) been fixed with 4.3.
