The 305 equal temperament divides the octave into 305 equal parts of 3.934 cents each. It has a flat tendency, with the 3, 5, 7 and 11 of the patent val all flat, and it tempers out 2109375/2097152, the semicomma (orson comma) in the 5-limit, 2401/2400 in the 7-limit, and 243/242, 441/440, and 540/539 in the 11-limit.

Template:EDO intro

305edo has a flat tendency, with the 3, 5, 7 and 11 of the patent val all flat, and the equal temperament tempers out 2109375/2097152, the semicomma (orson comma) in the 5-limit, 2401/2400 in the 7-limit, and 243/242, 441/440, and 540/539 in the 11-limit. It provides the optimal patent val for 7- and 11-limit neominor temperament.
