The step pattern for a modmos uses the characters L and s, either arranged differently from the true mos pattern or may include the characters A, c, and d. Each character has a value represented in large and small steps. It is recommended to use a step pattern whose value of L's and s's matches that of the true mos pattern. The table below shows the sizes of each supported step type. | The step pattern for a modmos uses the characters L and s, either arranged differently from the true mos pattern or may include the characters A, c, and d.
