nimo - \once \set should not fall back on a prefattory setting while \unset
should.

or is there an easy way to redefine the initial setting of the
fingeringOrientations per voice?

you can set:

\layout {
  \context {
    \Score 
    fingeringOrientations = #'(right)
} }

but then this is the default for all voices!

and the behavior of \override is different:

take for example

\relative { 
  \override NoteHead  #'color = #blue
  \set fontSize = #-5
  c4 c4
  \once \set fontSize = #5
  c4
  \once \override NoteHead  #'color = #green
  c4 |
  \override NoteHead #'font-size = #-5
  c4 c4
  \once \override NoteHead #'font-size = #5
  c4
  \once \override NoteHead  #'color = #green
  c4
}

where the last note head has the font size as overriden before! this
beahvior applies to the color override, too.

thanks

btw: writing fingeringOrientations = #'right brings Lilypond to crash!
