Actually, the MIDI output won't necessarily be correct.  Using
\transpositon seems to freeze the pitch so \transpose does
nothing to the MIDI, but does affect the printed output.

I've reported this a couple of times to the bugs list, but been
ignored.

Try this:
 \score {
        \transpose c' bes
        <<
                \relative c' { c1 }
                \relative c' { \transposition bes d1 }
        >>
        \midi{}
  }

You should get a unison, but instead get a major second in the MIDI
output.
