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
