Let me reword it and give a little more background.

I want that fingerings in single NoteEvent are affected by
*Orientations-settings as well as NoteEvents in EventChords.
(Currently this works only for StringNumber, although I've no clue why.)

I thought wrapping single notes into an event-chord while nicely
sorting their 'articulations and 'elements would be the way to go,
thus my polite-event-chord-wrap!-coding.

If not, I have no good idea where to start to tackle the problem
directly. Looks like I need more hints...


Here an example to play with:

\version "2.19.36"

\layout {
  \context {
    \Voice
    fingeringOrientations = #'(left)
    strokeFingerOrientations = #'(up)
    stringNumberOrientations = #'(right)
  }
}

{
  c'2-3\5 -\rightHandFinger #1
  <
   c'-3\5 -\rightHandFinger #1
   e'-2\4 -\rightHandFinger #2
  >
}

Cheers,
