Re: Non-printing score-wide dynamics

[David Sumbler]

Yes, I now see that 'mid' is treated as a stand-alone music expression,
so that Staff and Voice contexts are added automatically.  This is
confirmed by adding \mid to the printed output.

So my original question now becomes: how can I add dynamics to the 'mid'
staff and have them applied to all staves?

I have tried creating a 'mid' staff explicitly, thus:

midiStaff =
\new Staff {
    \time 4/4
    \new Voice \with { \remove "Dynamic_engraver" } {
        \mid
    }
}

and in the \midi block I put:

\midi {
    \context {
        \Score
        \consists "Dynamic_engraver"
        \consists "Dynamic_performer"
    }
}

But this did not work.  The dynamics in midiStaff seem to be ignored
altogether in midi, although they do appear in the printed score if I
add \midiStaff to the relevant \score block and the context changes to
the \layout block.  But then with this context change the dynamics from
all of the instruments appear above the top stave.

What I want is for the individual instruments' dynamics to remain with
and apply to them, but simultaneously to allow any dynamics in the
normally invisible midiStaff to apply to all of them.  Is this possible?
