Theory
190edo is distinctly consistent in the 15-odd-limit with a flat tendency, as harmonics 3 through 13 are all tuned flat.
The equal temperament is interesting because of the utility of its approximations; it tempers out 1029/1024, 4375/4374, 385/384, 441/440, 3025/3024 and 9801/9800. It provides the optimal patent val for both the 7- and 11-limit versions of unidec, the 72 & 118 temperament, which tempers out 1029/1024, 4375/4374, and in the 11-limit, 385/384 and 441/440. It also provides the optimal patent val for the rank-3 11-limit temperament portent, which tempers out 385/384 and 441/440, and gamelan, the rank-3 7-limit temperament which tempers out 1029/1024, as well as slendric, the 2.3.7 subgroup temperament featured in the #Music section. In the 13-limit, 190et tempers out 625/624, 729/728, 847/845, 1001/1000 and 1575/1573, and provides the optimal patent val for the ekadash temperament and the rank-3 portentous temperament.
The 190g val shows us a smooth path to the even higher limits. This extension tempers out 289/288, 561/560, 595/594 in the 17-limit; 343/342, 476/475, 495/494 in the 19-limit; and 391/390, 529/528 in the 23-limit.

Subsets and supersets
Since 190 factors into 2 × 5 × 19, 190edo has subset edos 2, 5, 10, 19, 38, and 95.

- 190et (190g val) has a lower relative error in the 23-limit than any previous equal temperaments, being the first to beat 94. However, 193, only slightly larger, beats it.
- It is also prominent in the 13- and 19-limit, with lower absolute errors than any previous equal temperaments. It beats 183 in either subgroup and is bettered by 198 in the 13-limit, and by 193 in the 19-limit.
