If you write everything “in C” you can use it for the score directly (I 
guess that’s what you call “orchestral pitch”?).

You are right: For the transposed parts with midi in C you need 
\transposition. But you don’t have to rewrite everything, just use 
\transpose too:

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

\version "2.19.83"

altosax = \relative {
  \key c \major
  c d e f g a b c
}

horn = \relative {
  \key c \major
  c d e f g a b c
}

trombone = \relative {
  \clef bass
  \key c \major
  c d e f g a b c
}

\score {
  \new StaffGroup <<
    \new Staff \altosax
    \new Staff \horn
    \new Staff \trombone
  >>
  \layout { }
  \midi { }
}

\score {
  {
    \transposition es
    \transpose es c' \altosax
  }
  \layout { }
  \midi { }
}

\score {
  {
    \transposition f
    \transpose f c' \horn
  }
  \layout { }
  \midi { }
}

\score {
  \trombone
  \layout { }
  \midi { }
}
