Harm I don't use MIDI so a custom function could work great yes for visual
spacing. But please bear with me on this for a second. If the durations
command already spaces them out then why doesn't this work *every* time? I
understand both commands are independent yes thank you. But I presumed that
I needed durations to space out the notes correctly like Gould and
publishing houses all over do.

Why would I need a custom function to do what featherdurations does if I'm
misunderrstanding?
I wouldn't even know how to make this function besides. Sorry.
