This command reports the minimum and maximum step values in the selected tracks or steps. The command also checks for clipping, which can be caused by excessive track velocity or velocity modulation. If a step selection exists, it takes priority, and only the selected steps are included. Otherwise all steps of the selected tracks are included. The step values are interpreted as unsigned integers from 0 to 127, regardless of track type. When applied to note tracks, the command reports velocities, but for other track types, the meaning depends on the context.
