PDF Conversion, Audiveris software
Uploaded a PDF document transcription of "you are the Sunshine" by Stevie Wonder, for guitar.
The process was relatively fast, less than 60 seconds
The transcription, downloaded and then opened in MuseScore 3.03
The transcription was a mess. What appeared to happen is the rhythmic timing was off so that it was necessary to open a new score, copy and paste the output from Audiveris software, and then edit the music.
It is easier than re-writing everything.
To be fair, I am not using the most current version of Musescore, we will continue testing and report whether or not current versions can handle the output better.
