Hi Kieren,
What's the current best snippet for rendering polychords? I know the GSoC chord stuff
is still in air traffic control, but the snippet found
at<https://lists.gnu.org/archive/html/lilypond-user/2012-02/txtmAr2kxZ1Uy.txt>
definitely doesn't work, and is likely far from optimal given the decade-plus of
advances in the codebase.
I don't have much time at the moment, but as a first pointer:
The snippet worked as late as 2.18.2. What broke it after that is that
the meaning of c1:5.9-.11.13- in chordmode has changed:
\version "2.18.2"
\chordmode {
c1:5.9-.11.13-
}
yields
in 2.18.2, whereas in 2.19.83, it yields
The culprit seems to be the added support for power chords: In 2.18.2,
c1:5 generated a c major chord; now it only generates a power chord
fifth. My guess would be that Valentin V.'s chord name cleanup in
78225bc1b386e12dc was the point when this changed.
