Omnitetrachordal MODMOS scale

10L+2s

12 tones (5+2+5)

Pajara MODMOS. Good for most any ratio of L to s.

P = 1.1300083763

L = 100.00 to 120.00 cents (101.95 cents @ P)

s = 0.00 to 100.00 cents (90.23 cents @ P)

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

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

MOS generator = L (100.00 to 120.00 cents)

MOS period = 1/2 octave (600.00 cents)

notable EDOs: 22, 32, 34, 46
