Can you please provide all precise the file you used for reproducing the issue you are experiencing? Also try to provide the exact error you see. From your explanation I do not know what exact error you mean. I have not heard of a term like "sigh mesures" or "pause mesures".

My best guess is: If you refer to the fact that MuseScore might show multi measure rests and alphaTab not, this is not a bug and also not specific to MusicXML. alphaTab does not have any feature yet to render multi-measure rests. In MuseScore this grouping is activated dynamically with the shortcut M when the music sheet is rendered. If this is the case please open a feature request via Discussions and explain in a proper fashion what you need and why.

@brusand From the display the issue looks valid. But I'll have to check in detail what is actually written in the MusicXML file to verify if it is an alphaTab import or MuseScore export issue.

The file upload dialog is right below the textbox when adding new comments to the issue. Or just drag&drop it to the box. https://docs.github.com/en/free-pro-team@latest/github/managing-your-work-on-github/file-attachments-on-issues-and-pull-requests. You just need to zip the files because GitHub does not allow all formats.

Your attempt to send the file via E-mail did not work.

I gave it a try on my side and it seems this is rather a missing feature than a bug. The affected rests look like this:

<measure number="2">
	<note>
		<rest measure="yes"/>
		<duration>4</duration>
		<voice>1</voice>
	</note>
</measure>

They have 1 rest with duration 4 inside the XML. This is what alphaTab currently supports. But the important part is the measure attribute. According to the spec this means:

If the measure attribute is set to yes, this indicates this is a complete measure rest.

alphaTab currently has no support for "full bar rests" similar to the fact it does not support multi-bar rests. Full bar rests are denoted as whole rests. Adding full-bar rests should be fairly straight forward.
