It seems the input doesn’t distribute the fingerings correctly for left-hand fingerings in staff A. This doesn’t matter if the voice is a down stem from staff A, or an upstem from staff B. Am I missing something? Obviously I can enter one note at a time, but that is honestly ridiculous with the project I am currently working on.
I’m not sure if this will work in your situation, but try typing the letter L before the numbers.
Ooh, that works thank you! Hope they can do some wizardry behind the scenes to give a smarter fingering input system.
