Z = randomise root X = randomise octave C = randomise instrument V = randomise note length P = stop Works best in Scratch 1.4's turbo mode.
The last one of these I made was pretty dumb, so I made this better one. It's still kinda buggy, though. Top left watcher = octave modifier Top right = major (top)/minor (bottom) root Bottom left = instrument # Bottom right = note length The line used to show what note was being played, but it's kinda messed up now.
