Slider Core-AsymmetrySlider Core Asymmetry Slider Core Asymmetry uses an asymmetric track structure, with a normal rhythm track on one side and a smooth track and limit points on the other side. This makes the feel smoother. There are two styles of asymmetric track structures: smooth version (A) and setback version (B). Version A has one limit point at the end, and version B has two. Super Dense Core further increases the number of track sections based on Dense Core,
