Beams of sixteenths

[Johannes Roeßler]

Hi,

professional editions often try to avoid angles that let visual staff 
lines between the beams - and when dealing with notes shorter than 
eighth notes,
the beams should not cross the staff lines - I now could change them all 
manually - but that's not really feasible (or not that what I'd like to do)

Is there any option I can set to handle this?

{
  \time 2/8
  f'16[^"a" c']
  \once \override Staff.Beam.positions = #'(2 . 1.6)
  f'[^"b" c']
}
