People have been doing this kind of thing with trackers for some time. Here's Vache by Venetian Snares, from 2006: https://www.youtube.com/watch?v=c2f5gOo1VEM https://www.youtube.com/watch?v=c2f5gOo1VEM And here's a webcam video of the sequencer data scrolling past: https://www.youtube.com/watch?v=zGK-EzEa45U https://www.youtube.com/watch?v=zGK-EzEa45U The techniques are much older. Here's a screengrab of the OctaMed tracker running on an amiga, playing back the original drum tracks from Aphrodite's jungle classic Beats Booyaa from 1994: https://www.youtube.com/watch?v=bkVSe9DubE8 https://www.youtube.com/watch?v=bkVSe9DubE8 And here's the whole of Beats Booya to hear it in context: https://www.youtube.com/watch?v=vts6rqJHMK8 https://www.youtube.com/watch?v=vts6rqJHMK8 Real producers chop their beats in hex ;) EDIT: also, most music software includes something called an arpeggiator, into which you play chords, which it breaks up into little sequences of notes according to different parameters. Set the interval down to 20ms or so and you've got your black midi :) That's also how you get those distinctive chord-like sounds out of monophonic soundchips in oldschool video games.
