Yeah, by “chart” I mean the actual 4K note patterns.
What I was really curious about is how you generated or designed them. Since the music doesn’t seem to have a very obvious note-to-beat structure, I expected the notes to feel somewhat random, but the patterns actually feel very familiar and “authored”, like something you’d see in a proper 4K rhythm game.
Did you hand-write the patterns, use some rules to generate them, or generate them procedurally somehow?
