A bunch of questions...

[Dominic Sacré]

Hi again...

I've been working with lilypond for a while now, but there are some things I 
really couldn't figure out myself...

1)
I've got three staffs (voice, treble, bass). Now I want the empty parts of 
the voice-staff to be removed (i.e. a "harakiri-staff"), but if I include 
"\translator { \HaraKiriStaffContext }" in the paper-section this will affect 
all staffs. 
The problem is that some parts of the treble-staff only contain rests, too, 
but these schouldn't be removed.
How do I use "harakiri-staff" for only one staff?

2)
If I have something like
    \property Voice.TupletBracket \set #'tuplet-bracket-visibility = ##f
    \property Voice.TupletBracket \set #'direction = #1
    \stemDown \times 2/3 { d'8( e'8 )d'8 }
(i.e. a triplet with a slur) the "3" collides with the slur.
Is there a way to change the the position of the "3", so that it will be 
above the slur?

3)
Is it possible to put one note (or the note head) in parentheses?


Thanx in advance for your help,
