Parasoft tunings of 4L 5s have a step ratio between 4/3 and 3/2, implying a generator sharper than {{nowrap|7\31 {{=}} 270.97¢}} and flatter than {{nowrap|5\22 {{=}} 272.73¢}}.


Parasoft tunings of 4L 5s have a step ratio between 4/3 and 3/2, implying a generator sharper than 7\31 = 270.97¢ and flatter than 5\22 = 272.73¢.
Parasoft 4L 5s EDOs include [[22edo]], [[31edo]], [[53edo]], and [[84edo]].
 
Parasoft 4L 5s EDOs include [[22edo]], [[31edo]], [[53edo]], and [[84edo]].
* [[22edo]] can be used to make large and small steps more distinct (the step ratio is 3/2).
* [[22edo]] can be used to make large and small steps more distinct (the step ratio is 3/2).
* [[31edo]] can be used for its nearly pure [[5/4]].
* [[31edo]] can be used for its nearly pure [[5/4]].
* [[53edo]] can be used for its nearly pure [[3/2]] and good [[5/4]].
* [[53edo]] can be used for its nearly pure [[3/2]] and good [[5/4]].


The sizes of the generator, large step and small step of 4L 5s are as follows in various parasoft 4L 5s tunings.
