@mandlebro I'm sure it could make generic Chopin that isn't too far removed from the stuff he wrote, but it wouldn't be able to come up with flashes of genius that characterize a lot of his pieces. for instance I was listening to the Grand Polonaise recently and noticed that he's using the exact same chords as Op.9 no.2 right down to the flat 9 descending line on the dominant chord that then turns to a pretty obscure Fm->Bdim->Fm in the left hand that I've seen nobody other than him do, so I think he does have a consistent bag of learnable of tricks that he's used all over the place
