[JW Lua] Weird accidental behaviour

Wed Jul 8 18:33:57 CEST 2020

With your script, running on your file, FCAccidentalMod:LoadAt returns true
if there is an acci mod and false if there isn't one. What's the issue?

If the question is, "where did that -54 come from?", the answer is Finale
calculated it and put it there. I wouldn't worry about where it came from.
Instead, I would set the value you want and save it. Don't forget to set
the note detail flag on FCNoteEntry.

If you are not seeing the results you think you should see after running
your script, use my plugin to compare the changes made by your script to
those identical changes done manually. That will show you what your script
is lacking.
