I think I might have noticed this before, but in the example below, all the "re" noteheads that are stem up that should be open (half note, dotted half note) are filled. Whole notes are not affected.
====
\version "2.16.2"
notation = { \aikenHeads \time 3/4
\key c \major
d2. d' d'' d'''
d'2 d'4
\stemUp \time 2/4
d2 d' d'' d'''
}
\score {
{ \notation
\transpose c d { \notation }
}
}
