Over the years, I have never fully mastered the copy and clear functions under track and pattern jobs. Often, I seek to copy all phrases from a single track from one pattern section to another pattern track section, but often find that other unwanted and unselected tracks go with it, why? Then, when I attempt to clear out the track now filled with the unwanted patches, both the track phrases I wanted in the first place as well as the unwanted patches are gone. Why do some user phrases on other uncopied tracks travel together with the one track I seek to copy? I read the manual but couldn't find an answer. I discovered looking at the patch screen that populated tracks with user phrases are preceded by either a solid square box OR a dotted square box. Seems like the dotted square box phrases are my unwanted hitchhikers. I am able to clear it from the patch screen without losing my other copied track... What are these dotted box user phrase? What am I doing wrong to let them come over in the first place?
