10/9 equal temperament
Using a Just 10/9 whole tone as the basis of an equal temperament tuning results in an interesting non-octave tuning. As every interval is a multiple of 10/9, the resultant tuning would be a subset of 5-limit Just intonation. This can be also viewed as generating a subset of minortonic temperament.
