Omnitetrachordal MODMOS scale

13 tones (5+3+5)

Tetracot MODMOS. Best tuned at high values of L/s.

P = 5.1745609664

Q = 10.4523018119 (4/3 = 3L+1.5s)

L = 92.31 to 171.43 cents (147.07 cents @ P, 158.44 cents @ Q)

s = 0.00 to 92.31 cents (28.42 cents @ P, 15.16 cents @ Q)

9/8 = L+2s (171.43 to 276.92 cents)

4/3 = 3L+2s (461.54 to 514.29 cents)

MOS generator = L+s (171.4 to 184.6 cents)

notable EDOs: 20, 27, 34, 41
