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
