I want MIDI only for a specific tag

[address@hidden]

I have a peace of music that has a Staff and a TabStaff but the music is 
not the same. How would I create the midi so it only plays the tag that 
is used in the Staff

In the sample I only want MIDI for the tag myStaff.

Sample code
%% Start
\version "2.19.15"

\header {
  title = "Test of MIDI"
}

global = {
  \time 4/4
  \key c \major
  \tempo 4=100
}


melody = {
  \global
  \tag myStaff { c'8 d' e' f' g' f' e' d' c'2 r2}
  \tag myTab { c'8 d' e' e' g' e' e' d' c'2 r2 }
}


\score {
    \new StaffGroup <<
    \new Staff
    \keepWithTag myStaff {\melody }
    \new TabStaff
      \keepWithTag myTab { \melody }
  >>
  \layout { }
  \midi { }
}
%% end
