The Four Mistyschism Scales

A hoary eccelesiastical joke has it that mysticism should really be
spelled "misty schism", so this is how I am spelling the four Fokker
blocks which come from misty and the schisma. The two most notable
things about these scales is that Scala classifies all four of them
as well-temperments, and that this concludes the classification,
though I'll check the latter claim. Mistyschism2 is the same scale as
Scala's duoden12.scl, about which we read "Almost equal 12-tone
subset of Duodenarium".

Is Kirberger's approximation to 12-equal in Scala? It would be
interesting if you actually had to go all the way out to atomic to
maximize the number of Scala matches in this big 12-tone exercise of
yours.

Is atomic a comma of 12-et?

Yes. <12 19 28|161 -84 -12> = 0
(Did I notate this incorrectly?)

Wow. Is the tuning list ready for this kind of stuff? I could go up
to the epimericity of the atom.

Well, this is probably the only way you're going to get Kirnberger's
tuning (the one that's a JI approximation of 12-equal: a chain of
schisma-flattened fifths), and that's the sort of tuning you might
find in Scala.
