Omnitetrachordal MODMOS scale

12L+8s

20 tones (8+4+8)

diminished; 3 forms; best at high L/s

P = 16.3836241662

Q = 41.9590604155 (4/3 = 5L+2.5s)

L = 60.00 to 100.00 cents (96.09 cents @ P, 98.44 cents @ Q)

s = 0.00 to 60.00 cents (5.87 cents @ P, 2.35 cents @ Q)

9/8 = 2L+2s (200.00 to 240.00 cents)

4/3 = 5L+3s (480.00 to 500.00 cents)

MOS generator = L+s (100.00 to 120.00 cents)

MOS period = 1/4 octave (300.00 cents)

notable EDOs: 32, 44, 56, 68, 80
