Believe it or not, not everyone who uses Elektron gear DJ’s or plays EDM. Some of us play guitars, bass, vocals, drums, etc. , and we can’t be plinking buttons every 15 seconds to change a pattern.
If Elektron puts in a song mode, or the ability to save pattern chains, people don’t have to use it, but at least it’s there for those of us who find it indispensable.
