help to manually fix conversion errors for beatLength from ~2.10 to 2.22.0

[Kenneth Wolcott]

Hi;

I recently downloaded the Brahms Horn Trio from Mutopia.

When using Lilypond 2.22.0 convert-ly I encountered only two errors.

Not smart enough to convert beatLength.
Use baseMoment and beatStructure.

cat -n HornMvtIII.lyi | grep beatLength
    75     \set Score.beatLength = #(ly:make-moment 3 16)
    77     \set Score.beatLength = #(ly:make-moment 3 8)

I've looked in the Notation Reference.

I'm not at all sure how to manually perform the conversion.

Please advise.

Thanks,
Ken Wolcott
