This is clearly pastiche, but I think that's the first step towards convincing compositions and then onwards to being original and interesting. I know there have been software methods to compose (and symphonies written by such), but I think the current AI/machine learning trend will allow the technology to move far faster than teaching it explicitly all the music and composition theory that you can.
But given that, it is still surprisingly coherent, melodic and generally enjoyable!
