MIDI Diagrams

[Mod & Op]

I'm looking for a book or a place to study diagrams like this:
this is from this month's Computer Music:

I rarely find tutorials that are like Ok this this a running baseline, or this is a trance chord progression. I love studying music theory but I'm trying to find stuff that's more closely related to what I'm trying to do.



Thanks guys,

These are chord progressions in a piano roll. Why don't you translate them into sheet music?
