Clever technology but I really don't see a need for it personally as I write my own & enjoy that process as well as hamfistedly creating chord progressions and stabs of melody.
If the aim is to create & express rather than "create content" or experiment with potential then it's more a diversion that path.
Of course, if the aim is to enjoy then it probably serves the purpose.
