or creates ramps between the steps. The following settings are available:

When Slope is set to Rising, Falling or All, the Amount parameter determines the time
of the ramp between two steps. The higher the setting, the smoother the transitions
between steps.

Snap
When Snap is activated, the level of each step can only be adjusted in quantized
steps of 1/12th.
