Uh, if you have a _custom_ staff context for which you want particular
overrides, you just do
\layout {
\context {
\Staff
\name "MyStaff"
\alias "Staff"
\override ...
\override ...
}
}
at the bottom, and then in the music you use
\new MyStaff { ... }
and, of course, the overrides will be in every staff of that type, and
not anywhere else.
Right, I have been using this custom staff approach and it works great for
"global" overrides that should _always_ happen on the custom staff. (I omitted
those overrides in my previous tiny example to make it tiny, with a comment saying so,
but in the process I may not have communicated clearly enough that I was trying to
achieve something else.)
My question now is about when say, a particular chord needs a manual
("non-global") override added _within_ the music (using \once), for it to look
right on the custom staff (as a by-product of the global overrides of the custom staff).
However, these same manual one-time overrides are not needed on a standard staff, and
look wrong there. (For example, needing to move note heads to a different side of the
stem to avoid collisions with other note heads on the custom staff, but not on the
standard staff.)
So once you've added these one-time overrides within the music you can only use
the music for the custom staff and not a standard staff. (Unless... there's
some way for a function that's called to do these one-time overrides to know
whether its being called from the custom staff context or a standard staff
context.)
