notation corruption on re-opening

• Apr 23, 2020 - 00:08

I have a repeated issue of my file being corrupted on re-opening.

The issue is with semi-quavers - images of what it should be ad what I get are attached ("coorect", "incorrect".

I am running Musescore 3.4.2.9788, revision 148e43f.

Please let me know what I need to do to prevent re-occurrence?

Thanks

Hi & thanks again

All my copies of the Compressed Musescore files give the corruption message & error per images reported earlier. I can't give you an uncorrupted version.

Please see bars 38 & 54 in the organ part - these are the images sent earlier.

I simply saved the files as a Musescore 3 File (.mscz) after they were finalised. These bars were definitley correct at the time of saving,

I am attaching the version of the file that is corrupted, and an XML export I sent to a colleague. Please compare bars 38 & 54 in the organ part - they are identical in the XML but not in Musescore on re-opening.

Is this a known issue?

Thanks again
Gordon

Hmm, several strange things going on here, but I can reproduce the corruption using your score by loading it, ignoring the warning, fixing the first example I see, saving under a different name, then closing and reload that new version.

I think the issue comes from the organ part, which remains corrupt even if I try to fix that staff in the score. So that's the fix for now, I think - delete and regenerate that part. But in order to fix the problem at our end, we'd somehow need to know how that happened.

Thanks for the response. Please confirm - when you re-load the saved corrected version, it opens ok (without corruption of the fixed bars)?

And for path forward - introduce a new instrument track, reproduce the organ track, then delete the original organ track (without copying anything from the original track, which has the corruption)? I want to be clear on path forward.

I have corrected the organ part several times & saved it in new versions - the corruption occurs each time for me.

Should I delete Musescore 3 & reinstall from scratch?

First, to confirm - yes, when I rel-loaded the corrected version, the corruption is gone.

Regarding the path forward - when I say you should delete the organ part, I don't mean to actually remove any music. Keep the staff in your score, you just need to delete the separate part by going to File / Parts, selecting it, and pressing "Delete". In fact, safest to just delete both parts. You can easily regenerate them later by returning to this dialog and hitting "All Parts"

Your score will still be corrupt, but with the parts out of the way, your fixes will "stick". The problem so far has been that you fixed the score but not the parts. Normally they are linked so any change you make to the score automatically updates the part, but that's part of the corruption here - somehow the score and part got out of sync, so no amount of fixing the score was fixing the part. Actually deleting the part, fixing the score, then regenerating the part, is the answer.

So - delete the parts, then fix the score. Save and reload to verify the fix worked. Once you verify all is well - the corruptions are fixed and stayed fixed on reload - then go regenerate the parts. You shouldn't have any further problems, but if you do, then definitely let us know as soon as possible so we have some chance of retracing your steps to understand how the corruption occurred.

And no, reinstallation almost never fixes anything.
