Show ledger line with hidden staff

[Rajesh Baskar]

Hi,

I'm trying to display just the notes without the staff lines but I need 
the ledger line to be displayed. I know you can use \stopStaff or 
\remove "Staff_symbol_engraver" but that removes the ledger line as 
well. Please advise and thanks in advance.



\version "2.22.0" \include "english.ly" \header { tagline = "" }
\score {\new Staff \with {\remove Time_signature_engraver
                          \hide Clef
                          \hide BarLine
                          \remove "Staff_symbol_engraver"

}

        {\set Staff.midiInstrument = #"Acoustic Grand Piano"
         \key c \major \time 4/4 \clef treble

\stopStaff  c'1
        }
       \layout { indent = #0 line-width = #25 }

        \midi { \tempo 4 = 168}}


Thanks,

Raj
