shifted rhythms, barlinecheck and \cadenzaOn

[Atte André Jensen]

Hi

The following .ly obviously breaks. The dotted halfnotes are displayed
where i want then (on the second 16th note) but barline checking
scrambles the remaining output. Is there a way to either

1) turn off barchecks?
2) use \cadenzaOn? (I couldn't find much documentation on this)
3) Is there a better way to achieve what I want?

-- begin lily --
RH = \notes \relative c'' \context Voice = RH {
    | r16 c8 c c16 ~ c16 c8 c c16 ~
    | c16 c8 c c16 ~ c16 c8 c c16 ~
    | c16 c8 c c16 ~ c16 c8 c c16
}

LH = \notes  \relative c \context Voice = LH {
    | r16 c2. 
    | c2.
    | c2.
}

\score {
    \context PianoStaff
    \notes <
        \context Staff = up <
            \time 6/8
            \clef treble
            \RH
        >
        \context Staff = down <
            \time 6/8
            \clef bass
            \LH
        >

    >
    \paper {
    }
}

Thanks in advance
