Omnitetrachordal MODMOS scale

10 tones (4+2+4)

Pajara MODMOS. Best at lower ratios of L/s.

P = 1.8849491924

Q = 4.8274237885 (4/3 = L+2.5s)

L = 120.00 to 600.00 cents (192.18 cents @ P, 328.12 cents @ Q)

s = 0.00 to 120.00 cents (101.96 cents @ P, 67.97 cents @ Q)

9/8 = 2s (0.00 to 240.00 cents)

4/3 = L+3s (480.00 to 600.00 cents)

MOS generator = s (0.00 to 120.00 cents)

MOS period = 1/2 octave (600.00 cents)

notable EDOs: 12, 14, 16, 22, 26
