OK, I think that's partially what I am asking about. I would just
never have found that myself. I would have asked the wrong question.
I think that Zbynek and I might be asking the same question. Language
is the barrier for both of us.
Let me re-phrase my question to see if I understand this:
Normally a half or whole rest sits on the middle line. The exception
is where there are multiple voices on one staff. There is yet another
exception to the exception. In piano music, even though there may be
two voices which are resting, for clarity the two rests which would
sit one above the other, are merged into one rest as if there were
only one voice.
In my case, Lilypond is not acting in this manner. This action will
have to be invoke manually. It isn't an explicit placement, it is an
invocation of a usual case that Lilypond isn't acting on.
This is something akin to the \override Staff.NoteCollision
#'merge-differently-dotted = ##t, but instead of notes being merged in
what would be considered a collsion, I want to override the usual
placement of the rests and instead, place them as if there were only
one voice.
I almost found what I was looking for then lost it. In some way I need
to override the placement of the rests. I think it was about having a
grob sit x number above middle C.
Override rest collision and place rests from both voices in the same
place in the score.
I'm using the word grob for the first time and I hope I've used it
correctly. I think this is what the other post was about. But I have
now clarified what I want lilypond to do.
I want to get this right because I think this is something important
for the documentation. Understanding how to ask a question is primary
in getting an answer. This question seems to have been a hard one to
ask.
cheers,
david
