The mission-active theme from the Space Cadet pinball table of Cinematronics's Full Tilt! series.
Not as widely recognisable as the main theme, as this tune didn't survive the conversion of the game to "3D Pinball: Space Cadet" that came with Windows back in the day. But it's still a good tune, and a good complement to the main theme.
This port cribs the instrumentation from the previous Space Cadet main theme port, so ideally it should work together to put both in the same hack, for whatever purpose. (But also, this is my first port, and I wanted the head-start while I was figuring out how MML worked.)
Version 1.1 fixed a couple of typos so all the tracks are the right length now.
