Dear users,
There is a bug in the Mac version where the Re half-note in \aikenHeads renders
as a quarter note in 2.16, and the problem just swaps for the whole note in
2.17. This has been reported to the bug list, but I'm wondering how to work
around it in the mean time. Here is a minimal
\ah = \set shapeNoteStyles = #'#(doThin reThin miThin faThin sol laThin
tiThin)
Use \ah wherever you would use \aikenHeads.
In my documents, since I *only* use Aiken heads, I do this:
\layout {
\context {
\Voice
shapeNoteStyles = #'#(doThin reThin miThin faThin sol laThin tiThin)
}
}
