Hi,

I had a look at your code and did some experiments.

I was very surprised that the following seems to work (outputting pdf and midi)

myL =
\layout {
  \context {
    \Staff
    \name MyCustomStaff
    \alias Staff
    \consists "Pitch_squash_engraver"
    squashedPosition = #0
    \override NoteHead #'style = #'slash
    \override Stem #'transparent = ##t
    \override Flag #'transparent = ##t
  }
  \context { \Score \accepts MyCustomStaff }
}

\score {
  <<
    \new Staff {
      c' d' e' f'
    }
    \new MyCustomStaff {
      c' d' e' f'
    }
  >>
  \midi { \myL }
}


Is this really valid code?

Cheers,
