Step ADD function in the Step Sequencer

this is the function we see in oldskool Amiga and Fasttracker . If we implant this to our beloved LMMS step sequencer , believe me friends, LMMS will become better than FLStuio. step ADD can be anything from 1 to 32 .

Start by learning how LMMS's step sequencer is structured and how its existing step editing works; the issue names no files, tests, or entry points. Before implementation, clarify what “Step ADD” means, how values from 1 to 32 affect sequencing, and what behavior would count as complete.
