For the most part the new samples still sound like melodic nonsense — in all but one of the examples the melody doesn't fit properly with the chords underneath.

For the most part the new samples still sound like melodic nonsense — in all but one of the examples the melody doesn't fit properly with the chords underneath. It really does feel like the output of a music blender. The style transfer is the most interesting bit IMO, as you get a sense of how it hears the source examples. For example, when transferring the opening to the Bach Toccata all the new samples miss out the same passing note (the fifth note in the sequence). To a human ear that note is important, and could easily have been incorporated into the new samples, but it seemingly doesn't activate enough neurons for MusicGen to care.
