I'm trying to use lilyjazz with 2.18.2 on os/x. I installed it with lyp and it seems to have worked. But when I try an example, a maj7 is rendered strangely as shown in the the screen grab below. The biggest problem is that it doesn't seem to like flats or sharps in chord names (see the ">"). But also, it is rending major chords with a superscript M, and minor with a subscript M. I had expected a triangle for major and minus for minor. And I can't seem to explicitly force it, e.g. using majorSevenSymbol.
The source code is right below the image. I've looked in the mail archive and tried many other things, but I can't get it. I must be missing something very basic!
\version "2.18.2"
\require "lilyjazz"
chordNames = \chordmode { e1:maj7 ees:maj7 }
melody = \relative c' { e1 ees }
\score {
<<
\new ChordNames { \chordNames }
\new Staff { \melody }
\new TabStaff {\melody}
>>
}
