I'm going to reply to this post because the mixture of top-posting and bottom 
posting is annoying.

You'll probably be better off if you use variables. With variables, you can 
define the musical material separately, and then have separate instances for 
creating a print score and a midi score.
\version "2.16.0"

topPart =  \drums { \time 2/4 \bar "|:"<<{hh8 hh <hh sn> hh }\\ { bd4 r16 bd8. 
}>> \bar":|" }

bottomPart =  \drums { \time 2/4 \bar "|:"<<{hh8 hh <hh sn> hh }\\ { bd4 r16 
bd8. }>> \bar":|" }

\markup{
   \line{
      \score{
         \topPart
         \layout{}
      }
      \score{
         \bottomPart
         \layout{}
      }%Score
   }%Line
}%Markup
\score{
   \topPart
   \midi{}
}
\score{
   \bottomPart
   \midi{}
}%MIDI
