It works pretty well. The "random" melody sounds rather human-made for me (of course, since you've programmed it:) )

Yeah. It picks between 5 pre-selected notes (and a rest, which is less likely to occur than the notes) at random and plays them with a sequenced rhythm.

I'd wanted to do something with a start and end that still made a somewhat different song every playback, but I just gave up on that and submitted what I had since I wasn't going to finish that by the extension's end.

i didn't realize you could use select with multiple numbers, that's way cleaner than the hacky stuff i tried with moses
