%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\version "2.19.48"

pizz = \markup { \larger \italic "pizz." }
midiPizz = \set Staff.midiInstrument = "pizzicato strings"

arco = \markup { \larger \italic "arco" }
midiArco = \set Staff.midiInstrument = "violin"

\score {
\relative c'' {
\new Staff \with { midiInstrument = "violin" } {
c2 \midiPizz c4^\pizz c |
\midiArco c2^\arco r \bar "|."
}
}
\layout { }
\midi { }
}

The above works as I would wish it to. However, I am wondering whether
it can be simplified.

1) Is there a way of combining \pizz and \midiPizz into one variable?
Preferably it needs to be attached to the note (as \pizz already is)
so that the printed marking can be placed above or below the stave.
Similarly, of course, for \arco and \midiArco.

2) '\unset Staff.midiInstrument' would be preferable to 'set
Staff.midiInstrument = "violin"', because it would not need to be
redefined in each instrumental part. However it does not work in a
voice context. Is there a way of reverting the midiInstrument to its
previous setting which could still be included in a variable?

Just curious, does changing the Staff.midiInstrument midstream produce more than one MIDI track? 


 

Below is one way to simplify your expressions.

I wasn't happy with this solution in that I couldn't find a way to apply a markup to the music _expression_ $note within the music function, and instead had to apply it to an empty chord preceding the note.

\version "2.19.15"

pizz = \markup { \larger \italic "pizz." }
midiPizz = \set Staff.midiInstrument = "pizzicato strings"
myPizz = #(define-music-function (parser location note) (ly:music?) #{
    { \midiPizz <>^\pizz $note  }
#})

arco = \markup { \larger \italic "arco." }
midiArco = \set Staff.midiInstrument = "violin"
myArco = #(define-music-function (parser location note) (ly:music?) #{
    { \midiArco <>^\arco $note  }
#})

\score {
    \new Staff \with { midiInstrument = "violin" } {
        \relative c'' {
       
            c2 \midiPizz c4^\pizz c |
            \midiArco c2^\arco r \bar "|." \break

            c2 \myPizz c4 c |
            \myArco c2 r \bar "|."
        }
    }
    \layout { }
    \midi { }
}
