If there's some intuitive reason for choosing different logical equivalents, perhaps that should be reflected in different pitch alterations anyway.

```Graham Breed wrote me a nice note suggesting defining some kind of

I think I'll probably go with 'cheaty' definitions of pitch alterations,
like +/- 101/400 (or 1001/4000 or whatever seems most appropriate:-)

Yes, sorry that went privately. I forgot the "shift-ctrl" to reply. The idea is you can only have one set of quartertone symbols at a time, but you can use a \tweak or \override to switch between sets. I have proof of concept examples for pure/mixed Sagittal.

The cheating looks fine until you want to do transpositions. Transposing C up-a-quartertone up by the same quartertone won't give C sharp, for example. If you think it should that's an indication you're treating quartertones equally, of course.
