I do use uneven step edits often when trying to add variations to dense note-event filled tracks, use them to delete hits sometimes onbeat, other times offbeat. I guess stuck from the olden tracker days, the F9 to F12 keys still get used a lot travelling through patterns, cutting whatever pattern length that is being used in 4s. Page up & page down keys are also handy in that regard, same as for the home & end keys for fast travel . I love the flexibility.
I’m realizing there might be a good use case for a key binding that simply increments or decrements the step length by one so you can quickly just press up or down to get to the number you want. this would get you to those rarely used step lengths like five, seven, and nine in the rare cases when you use them. Maybe I’ll explore that tomorrow.
I have my instruments set up that way so I don’t select them with the number pad but rather just Alt+arrow up and down the list until I get to the one I want.
