I listened to Vulture Culture yester-day, and I learned a couple parts. First, I have what I guess is a synth part from "Separate Lives." The closest match on my keyboard is actually calliope. I'd thought that this is just the same phrase repeated (so it's played four times), but the third iteration has a different rhythm, and the fourth iteration (which I don't have yet) has different notes.
I also figured out that the synth part that begins the song is just A notes an octave apart. I'm not sure how long that lasts though or if the notes change later on.
