This extension of 5-limit diaschismic adds prime 17, and can be seen as the trivial tuning of [[MVP archagall]] in its minimal prime subgroup by equating [[85/64]] with [[4/3]] by tempering out their difference of [[256/255]] (S16). Therefore it also tempers out [[289/288]] (S17) and thus equates [[17/15]] with [[9/8]] due to tempering out [[136/135]] (S16⋅S17). It could be described as the 10 & 12 temperament with strong emphasis on 12edo being the better tuning on the 2.3.5.17 subgroup, implying ideal tunings of 34edo, 46edo or 80edo. | This extension of 5-limit diaschismic adds prime 17, and can be seen as the trivial tuning of [[MVP archagall]] in its minimal prime subgroup by equating [[85/64]] with [[4/3]] by tempering out their difference of [[256/255]] (S16).
