Hi, I'm new to this thread, I'm listening to the version of the song that's on page 9...
Here's what I would do if I had a copy of that mmp file:
-Add c* saturator to piano, aiming for a "vintage sample" kind of sound
-Re-pitch the hihat, kick and snare, maybe add fine-tuned, very short calf reverb to hihat and snare
-Put a peak controller on the kick and have it duck the instrument parts by different amounts
-Add various stutter effects to the vocal samples and use them to add interest
-Have the patterns on the piano switch over to other, new instruments
-Add additional percussion patterns to enhance the progression of the song
