The [[step ratio]] (also simply called the ''hardness'') of MOS denote the relative sizes of the large and small steps and is an important factor for classifying MOS patterns. The step ratio of 2:1 — which means that the large steps are double the size of the small steps — is called the ''basic'' form of the MOS. When the difference between the large and small steps increases (i.e., the large step becomes larger and the small step smaller) the MOS is considered harder, as the contrast in size is more pronounced. Conversely, when the size difference decreases (meaning the large step becomes smaller and the small step larger) the MOS is considered softer, due to the subtler contrast.
File:5L 2s hard.png|When the L:s ratio is 3:1, the MOS is hard. 17-EDO contains the hard 5L 2s.
 
File:Basic 5L 2s.png|When the L:s ratio is 2:1, the MOS is basic. 12-EDO contains the basic 5L 2s.
To find the equal tuning of some hardness of an MOS, simply input the relative size of the steps and multiply them by the number of steps. For example if we want to find the tuning which contains the 5L 2s pattern with the hardness of 2:1, we simply calculate 5(2)+2(1)=12, showing us that 12-EDO contains it.
