OTC 12L 7s
Omnitetrachordal MOS scale
19 tones (8+3+8)
Meantone MOS; P<0 (oddly, neither this scale nor its dual can be tuned with a perfect 3/2!)
P = -4.8459060415
Q = 20.7295302077 (4/3 = 5L+2.5s)
L = 63.16 to 100.00 cents (97.26 cents @ Q)
s = 0.00 to 63.16 cents (4.69 cents @ Q)
9/8 = 2L+s (189.47 to 200.00 cents)
4/3 = 5L+3s (500.00 to 505.26 cents)
generator = 4/3
