I now have my Lilypond JI code working with the Extended Helmholtz-Ellis
Pitch Notation. This is something I've been putting off for some time
because it means the function that determines the original accidental
has to know the original ratio that it refers to. After the more recent
discussion here, I decided to use a global list to keep lookups of
alterations to ratios, and all is well so long as you don't transpose
anything.
You can get the code from the git repository:
https://bitbucket.org/x31eq/microlily
I have a "don't care" attitude to licensing, which is made explicit in
the README. So, if you want to copy any ideas for your code for other
JI notations, feel free. The same input code should work for different
notation systems, as it currently does for different kinds of Sagittal
and the new Helmholtz-Ellis.
