The MIDI version is richly informative. There are long passages where there’s almost no rhythmic correspondence between the notes as written (and as “performed” in the MIDI) and the way that humans perform them. People are playing the same notes in the same order, but have pretty much thrown Bach’s written rhythms out the window. But the MIDI isn’t a very satisfying listening experience.
In my video example above, my variations were as follows: First, I removed the hi-hat entirely (variation 1), then I added a kick and snare hit (variation 2), and finally I added kick and snare hits while removing snippets of the hi-hat pattern (variation 3). All of which is in addition to an already interesting yet repetitive beat sequence.
