This is a bizarre request--1216/1215 comes out a comma if you map
19 to 94, and 57/56 if you map 19 to 93. To get them both to be
commas, you need to screw the mapping of 7.

the shocking implication is that, unlike the vast majority of
wilson's scales, evangelina is not a constant structure scale. this
is seen immediately in that the interval from 135/128 to 45/32, which
is 4:3, is 10 steps in the tuning, while the interval from 1/1 to
4/3, also 4:3, is 9 steps.

does kraig have any comment?
