I'm not sure it's a matter of learning to use generative programs as much as it is the program not being up to snuff for casual use.
Yeah, if you fiddle with your input, you can get a more realistic result, but that's not the only way to use that kind of software. It's perfectly fine to use them for casual things where realistic results aren't the point.
Now, is this the C/ to post them in? Probably not, though I haven't seen any rule against unrealistic results, and there are plenty of posts containing things like this.
Philo does it as a game, where the point is to input songs and take whatever the program spits out and then people guess what the input was. Again, not sure this is the place for that, but the mod or mods don't seem to object, and there's never enough down votes to point towards the community as a whole caring enough to try to make that a rule.
I think the annoying thing is there is a community for this game, and he posts the same things to both. I can block that community, but I enjoy this one. I guess I just have to block him
