This scale is one of the few I extracted from the archive two months ago,
when I went thru the archive.

Scales are big. Takes years to learn your way around some of them. But
preliminary playing gives me the feeling that "Fokker's 7-limit periodicity
block of 2048/2025 & 3969/4000 & 225/224" functions quite differently than
either my scale or its Keenan-tempered version.

No, no, no! I agree that one is quite different. But I wasn't referring to that Fokker scale, rather this one:

! fokker_12.scl
!
Fokker's 7-limit 12-tone just scale
12
!
15/14
9/8
7/6
5/4
4/3
45/32
3/2
45/28
5/3
7/4
15/8
2/1
4/3-------1/1
... ..
. . . . .
5/3-------5/4------15/8------45/32
