Here's something you can do in 2.19.83:
%%%%
\version "2.19.83"
\tagGroup #'(screenOut midiOut)
nc = {\tag #'midiOut <c c'> \tag #'screenOut c' }
nd = {\tag #'midiOut <d d'> \tag #'screenOut d' }
myScore = {\nc \nd \nc << \nd s~ >> \nd}
\score {\keepWithTag #'screenOut \myScore \layout{}}
\score {\keepWithTag #'midiOut \myScore \layout{}}
%%%%
And empty chord works in place of the spacer too:
%%%%
myScore = {\nc \nd \nc << \nd <>~ >> \nd}
