I use this for other purposes:

  allMusic = {
    <<
      \include "chordstaff.ly"
      \include "leadstaff.ly"
      ...
      \tag #'midiOnly \include "ticktock.ly"
    >>
  }

  \score {
    \removeWithTag #'midiOnly \allMusic
    \layout {
    }
  }

  \score {
    \removeWithTag #'scoreOnly \unfoldRepeats \allMusic
    \midi {
    }
  }

I don't think the \tag mechanism is suitable for the purpose I
described in my other posting.
