Does >anyone know of any such models? Note that there is a theoretical assumption embedded in your question, namely that simultaneous integration precedes sequential integration. In order for "notes" to exist as a perceptual/cognitive representation, we must presuppose a processing step that accurately extracts them from an acoustic signal. The psychoacoustic validity of a MIDI-like representation (one that depends on "notes") is open to some question, in my opinion. That said, I would also be interested to hear of such computational models.
