However, there is a score mismatch issue in the early stage of the distillation process, because existing methods mainly focus on using the endpoint of pre-trained diffusion models as teacher models, overlooking the importance of the convergence trajectory between the student generator and the teacher model.

A melody is then generated by feeding a random sample from that space to the autoencoder's decoder, along with the chord progression generated by the grammar.
