Triple harmonic scale

The augmented second interval is characteristic of much European folk
music. There are various single harmonic scales. Hungary uses two double
harmonic scales.

A triple harmonic scale might include the following conventional notes:

P8 2/1 1200c
M7 15/8 1088c
m6 8/5 814c
P5 3/2 702c
M3 5/4 386c
m2 16/15 112c
P1 1/1 0c

To fill it out, a diminished fourth is needed. Which of these sounds better?

32/25 427c
9/7 435.08c

What instrument can I obtain that will allow me to measure all these notes
precisely, hear them clearly, and use them in chords?

What can I buy that will allow me to play a triple harmonic tune with
theremin timbre into a computer file that people can listen to?

d4 9/7 435c

Above was the major scale. The minor seems to provide provide better
proportions:

P8 2/1 1200c
M7 15/8 1088c
m6 8/5 814c
P5 3/2 702c
A4 7/5 583c
m3 6/5 316c
A2 7/6 267c
P1 1/1 0c

Does anyone have experience with either of these scales?
