perhaps version 2.6.3 has some bug in midi generation. If I remember it  
was fixed in 2.6.4, but I'm not sure. in version 2.7.x, your example yelds  
a correct midi file.

you have to use a ChordNames context in the \score section

by "inside the lines" you mean inside the staff? if I get you right, you  
have to set the noteheads to slashes. these are "/" signs, not "\". For  
the last one I guess you should use markups with "\\".

Is this what you want?:

\header
{
title = "Improvise"
composer = "Jannik Jeppesen"
}

chordline = \chordmode {
  \repeat volta 20 {
    a1:m c g e:m
  }
}

rythmline = \relative c''
{
  \override NoteHead #'style = #'slash
  \override Stem #'transparent = ##t % or not
  \repeat volta 20 {
    b4 b b b
    b b b b
    b b b b
    b b b b
  }
}

\score {
  <<
    \context ChordNames {
      \chordline
    }
    \context Staff {
      \rythmline
    }
  >>
  \layout {}
}

\score {
  \unfoldRepeats \chordline
  \midi { \tempo 4 = 120 }
}
