They make the mercator and qian microalterations go in the opposite direction the interval suggests, which eliminates the need of knowing which direction you need to alter by. ''Alter'' is more than enough for the overwhelming majority of cases. | ||
So you have the fourth -1 fifth, alterfourth +52 fifths, mercfourth is -54 fifths and altermercfourth +105 fifths. Same with revol. | So you have the fourth -1 fifth, alterfourth +52 fifths, mercfourth is -54 fifths and altermercfourth +105 fifths. Same with revol and qian. | ||

== How to use for temps in/and higher limits == | |||
EPN can handle tons of temperaments that are based on the chain of fifths, obviously the rank-2 monocots, dicots, alpha-dicots, and hemipyth ones; but also rank-3 ones with a free generator for other primes. However, there is a special case when the septischisma is tempered out due to the prevalence of the super/sub usage for septimal. | |||
=== General case === | === General case === | ||
Can be used not necessarily with just fifths, can use ideally with fifths between 24\41 and 38\65 inclusive. | |||

=== Septischismic === | |||
Use the rightward names and symbols if the septischisma is tempered out since the poma is closer to 64/63 (the septischismic column). In there, the pomas and merccommas become are equated and often sound much closer to rumas and [[buzzardsma]]<nowiki/>s. If not, keep po and super distinct. There is no equivalent for septimal comma qian, on purpose. Assume ^/v are always [[aberschisma]]<nowiki/>s. This gives you a solid 13-limit basis that can be extended to [[olympic]]. | |||
