I used one new technique while composing this section: copy-and-paste within the matrix editor. You can see this around the beginning of measure 103, where the same pitch-classes are heard simultaneously in a high and low octave. I created the upper register first, then selected the notes that I wanted to copy. I used Control-c and Control-v to create the copy. Like when copy-and-pasting clips in the main window, the cursor icon changes to a clipboard, and an outline of the to-be-pasted material is shown so that you can position it as desired. As you will see, you can paste the copy onto any pitch level, and at any point in the measure. What is kept the same is the pitch intervals between notes and the rhythms between notes.

I also used the copy-and-paste technique with the three stepwise-descending-notes figure in this passage. After building the initial note of each set of four, I randomized those, and copy-and-pasted the three descending notes after. This way, I was able to randomize part of the melody, but avoid randomizing another part.

In this passage, I kept the "a note followed by three beats of rest" idea, then added onto the melody by taking two cues from the audio file. The first was the increasing surface rhythm of the upper part, which gave rise to the "three-descending-notes" figures. The second was the fact that the chords are still going on underneath that melody, so I added a second randomized set of notes underneath my upper part. At the end of the passage I continued the trend that I started with a finishing flourish that picks up sustained notes.
