Converting cents to ratios only makes even a bit of sense if you have some
preexisting music in some temperament, which you then want to approximate
in just intonation. But even that isn't really something that would be

I'm not sure if that's a viable road, but it might also be a good idea
to define these stencils in metafont. This might
Converting cents to ratios only makes even a bit of sense if you have some

So I've kludged around with Inkscape, and I'm attaching a few .svg files to
show what I'm getting at. These are *very ugly*, and I would want to spend
a good bit of time working on proportion, weighting, etc..

Take a look at conversions.ly (sorry; mround is the equivalend function in
the spreadsheet I use to do the same thing). Those functions will convert
the input (given as a fraction comprising two integers) into Lily's
semitone values. That should allow you to convert between just-intonation

What's the OLL repository?

sorry. You have to switch to the just-intonation-stub branch, which is

Maybe so, but the result is less portable because (if I understand correctly)
you'd have to have a custom font and have i
It would not, because the accidentals I use are in an open system of just
intonation (not a fixed scale) in which *any* conceivable ratio can be
represented (so long as I have the module for its respective prime
factors). This is a serious limitation of a lot of systems, in that the

If I understand the procedure correctly, wouldn't it be easier to use a
tool like fontforge add/adjust font glyphs?
