Prime Music returns

Last year I posted some music I had generated by factoring integers. I've been thinking about it off and on since then and last night I got something that I liked.
1.1K MIDI 336K MP3 (Both are 14 seconds long)

( The details )

I'd love to hear what you think!

ETA: I should mention that most of my changes amount to "do what mrmorse told me to."
