Omnitetrachordal MODMOS scale

7L+3s

10 tones (4+2+4)

Mohajira / neutral-thirds MODMOS; primes 3, 11 better at high L/s; primes 7, 13 better at low L/s

P = 2.5872804832

Q = 7.8650213288 (4/3 = 3L+0.5s)

L = 120.00 to 171.43 cents (147.07 cents @ P, 162.57 cents @ Q)

s = 0.00 to 120.00 cents (56.84 cents @ P, 20.67 cents @ Q)

9/8 = L+s (171.43 to 240.00 cents)

4/3 = 3L+s (480.00 to 514.29 cents)

MOS generator = 2L+s (342.86 to 360.00 cents)

notable EDOs: 17, 24, 27, 31, 37, 41
