Ok,

I have started a JI serial piece using John's Blue JI tuning. One of
the parameters I want to keep track of is the intervals between steps
in the row. For me this becomes a bit hard to keep track of. So, is
there a way to generate this kind of information in scala for instance
so I may avoid pencil and paper and fractional math. I can do it - but
I'm pretty lazy on that end.

For example my row starts on A and the prime p-0 row is

P-0 0 8 3 11 5 2 1 7 9 6 4 10 R-0

And John's tuning is

! C:\Cakewalk\scales\blue-ji.scl
!
Blue JI
12
! C
15/14 C#
9/8 D
6/5 Eb
5/4 E
4/3 F
7/5 F#
3/2 G
8/5 G#
5/3 A
9/5 A#
15/8 B
2/1 C

So my sequence starts with difference (A to F) = 1/3 , next
difference (F to C) = 1/6 = that is to say that the row should
reduce to a series of JI steps.
