Correcting beat counts in scanned score (Musescore 18.104.22.168071203)
I scanned a pdf score with 930 measures for my partner who is a classical musician (retired from 25+ years first flute at a major symphony). About half of the scanned in measures have the wrong duration values.
Some measures had, for example, double dotted 1/8 notes in the original but were entered by the scanner as single doted 1/8 so there is extra time in the measure and it is too long, there are whole notes in 2/4 measures, etc. When she changes a dotted 1/8 to a double dotted 1/8 note, musescore adds a 16th rest to preserve the incorrect duration. We haven't found a way to change the (too long) measure length beside inserting a new measure and copying the notes over, which is very time consuming since it needs to be done several hundred times. So far the only thing I can think to do is to write a python program to process the musicxml file, but it has been 9 years since I retired, and I was an OS geek only using python to process performance data.
The measures with incorrect duration are annotated with plus and minus signs, so it seems like musescore knows they are wrong and ought to be more willing to accept the corrections.
Anybody know how to fix this using the user interface? The google searches I have tried result in instructions that refer to interface bits that don't seem to be in musescore 4.
