Isn’t this backwards? The bugs with part-combined accidentals seem to arise
from the part combiner’s destroying information (and creating misleading
information) by reassigning notes to other voices. Instead of removing the
NullVoice which has the valuable original information useful to the Accidental
engraver, shouldn’t there be a way to make the Accidental_engraver ignore the
voices created by the part combiner? Here is an example that shows combined
issues with accidentals, lyrics, and dynamics.
