Music notation software produces incorrect output when combining parts with dynamics on empty chordsClassical musicians and composers using LilyPond struggle with a specific technical bug where the partCombine function fails to properly handle dynamics markings that end on empty chords, resulting in malformed sheet music output. This forces users to manually edit source code or find workarounds, significantly slowing down the composition and arrangement workflow. Current solutions lack adequate documentation or built-in fixes for this edge case.
