Launchin and morphin in 53 tone equal temperament. Most of the 53 notes were used here, I think. No particular subset was used so all 53 were available on the piano roll. I tried to use plenty of descending 1\53 steps in the voice leading. Since there are only 128 MIDI notes it was tricky for any one instrument to range much beyond 2 octaves. I simply tuned the bass 2 octaves down and the lead 1 octave up, then kept each instrument within its range.
