Structure is fun, but the structures i've been interested in aren't super musically obvious when you listen.
Use only 4 notes(that one made me think a lot), build everything around a comparator, make a patch then run it at audio rates.
Yeah, I know exactly what you're talking about. I used to love textures and feelings transmitted through drones, it's something I would like to incorporate into a more strict and melodic tune. Actually tried to end one of my songs in a droney way, not sure if that one came our right though, it's way too lightweight
