ties between different voiced notes

[Martijn Vromans]

Dear all,

As stated in the manual I use the \once \override Stem #'transparent = ##t method for the following bar, but the result is not as expected, because the hidden a flat is not drawn at the same place as the a flat in the other voice. I have enabled note collision. What do I do wrong? Is there a workaround?

This is the example:

<< {

s8 s32 \tieDown \stemDown bes,16. ~ \stemNeutral <bes aes' bes>2( \tieNeutral <c g' c>8) s8

}
\\
{

s8 s16 s32 \stemDown aes'32 ~ \once \override Stem #'transparent = ##t aes2(\noBeam \once \override \Stem #'transparent = ##t g8 s8

}
\\
{

aes,32[ f bes,-1 f' aes bes-1 f' aes] s2  \once \override Stem #'transparent = ##t <c, g' c>8\noBeam) b8\rest

} >>

All the best and thanks in advance,

Martijn
