There are several ways to handle this.

I always postprocess the MIDI output, eg. to split chords + 4 parts into
4 separate MIDI files, each having one part plus the chords (but with
decreased volume). It would be trivial to just leave the chords out.

Another way is using tags:

allMusic = {
  <<
    \tag #'scoreOnly \harmonics
    \sopranoStaff
    ... other staffs ...
  >>
}

%% Generate the printed score.
\score {
  \removeWithTag #'midiOnly \allMusic
  \layout { ... }
}

%% Generate the MIDI.
\score {
  \removeWithTag #'scoreOnly \unfoldRepeats \allMusic
  \midi { ... }
}
