I suppose lack of dynamic sign at the beginning of the music may be
the cause of the problem. See
http://lilypond.org/doc/v2.14/Documentation/notation/controlling-midi-dynamics
: midiMinimumVolume and midiMaximumVolume properties have an effect
only on dynamic marks, so a dynamic mark must be placed at the
beginning of the score if you want them to work properly.

In other words,

\version 2.14.0
\include "articulate.ly"
\score {
  <<
    \new Voice {
      c \mf d e f
    }
    \new Voice {
        \set Staff.midiMinimumVolume = #0.2
        \set Staff.midiMaximumVolume = #0.5
        c''\mf c'' c'' c''
    }
  >>
  \midi {}
}

works for me (i.e. the high c's are quieter than low melody).

HTH,

PS there is a bit different wording in Notation Reference than what i
wrote. Maybe it should be changed to simpler english?
