Omnitetrachordal MODMOS scale

3L+7s

10 tones (4+2+4)

The imperfect dual of OTC 7L+3s, this scale pattern barely qualifies as omnitetrachordal.

temperaments: sephiroth, sharp, dicot, contorted ripple?

P = 0.3865062201

Q = 2.4263858852 (4/3 = L+3.5s)

L = 120.00 to 400.00 cents (203.91 cents @ Q)

s = 0.00 to 120.00 cents (84.04 cents @ Q)

9/8 = L+s (240.00 to 400.00 cents)

4/3 = L+3s (400.00 to 480.00 cents)

MOS generator = L+2s (360.00 to 400.00 cents)

notable EDOs: 13, 16b, 23b
