Yeah, James, that's what he's saying. (By the way, hi!)
He's asking for the beatmap editor to have capabilities that will allow itself to automatically map parts of a song so the user doesn't need to "work so much from scratch".
This topic has been discussed before, as linked
here~
While it's possible on a technical level to implement random, automatic patterns that miraculously go with the song, the map would probably lack flow, excitement, and most importantly, that unique style. With a lot of practice and mapping skills, a beatmapper's style can evolve out, and there can be tons of awesome, innovative, fun things that can come out of it. I don't think an automatic beatmap maker can do any of that.
So yeah, going to render this invalid. Sorry! Play maps, pick up on mapping, have fun, and you won't need some generator to create epic beatmaps.
