Thanks for putting the bug report together, Darren. I was able to reproduce the behaviour you reported. I also tried removing the \ignoreCollide from your source just to see what happens, and I have to say that the output looks correct to me. See attached. The notes are both supertonics and the note shape seems correct. But I've never used Aikenhead notation so I may not be the best judge. I will create a tracker so we don't lose your input. In the meantime, could you send an example of good practice for colliding Aikenhead notes, or an image of what you think Lilypond should do in this situation? Cheers, Colin. -- Colin Hall

% I'm trying to create a score for four voices SATB that uses AikenHeads
(shaped
% notes). When two parts on the same staff overlap on the same notes (for
% example soprano and alto), it is customary to show the stems for the two
parts
% going different directions so each part realizes that it is to sing the
% overlapping notes.
% When I try to do this with LilyPond 2.14.2,
% 1. The heads face in opposite directions, which obscures the shape of the
head.
% 2. I tried suppressing the Note Head for one of the parts (made it
% transparent), however the stem does not meet the note head of the opposite
part.
% Example .ly code follows. It requires a bit of detail to demonstrate the
% problem. I have a screen shot I can provide if that would help (but this
% interface doesn't accept attachments).
% The bass staff demonstrates #1, the treble staff demonstrates #2.
% Thanks for any assistance
