Variables and tags are helpful.  Consider:

%%%%
\version "2.19.83"

asdf = \fixed c' {
  | c4 d e2
  | \tag #'display { <f g>1_\trill }
    \tag #'midi { \repeat unfold 4 { f8 g } }
  | a4 b c'2
}

\score { \keepWithTag #'display \asdf \layout {} }
\score { \keepWithTag #'midi \asdf \midi { \tempo 1 = 60 } }
%%%%
