Exporting altered note tunings to MusicXML

• Oct 14, 2020 - 21:02

Hello,

This score https://musescore.com/infojunkie/ya-labesyn uses altered note tunings, by manually adding cents to some notes (e.g. the first one is altered by 33 cents).

However, when I export the sheet to MusicXML, 2 unexpected things happen:
- The MusicXML file has an [alter] element for the first note with value 0.5, not the expected 0.33 or similar
- When I import the MusicXML file back into Musescore, the [alter]ed note loses the altered tuning

Actually, I see that the XML export code does not take altered note tunings into consideration, as per https://github.com/musescore/MuseScore/blob/master/mu4/importexport/int… it has hard-coded values for a few accidentals, but does not appear to read from the "Tuning" note property. Where can one submit a proper bug report?

Nope, see #303920: [MusicXML import] Floating-Point Alter tag interferes with import of accidental and #303918: Microtonal information in Alter MusicXML tag not preserved.

I think these issues pertain to MusicXML import, not export.

I think #303918: Microtonal information in Alter MusicXML tag not preserved. is about export

Or #311792: MusicXML export does not preserve altered note tuning

As for import, I see that https://github.com/musescore/MuseScore/blob/master/mu4/importexport/int… means that fractional tunings are not supported, effectively preventing any microtone import.
