Picked up your page. The issue is that you must set MIDI values on the supercontrol relative to the 0-127 range (or whatever its range is). So you cannot use 0, 1, 2, 3 for 4 sub ticks. Instead you need to use 0 / 3 * 127 (0), 1/3 * 127, 2/3 * 127, and 3/3 * 127 (127)... If these numbers don't work exactly, I might have the math a tiny bit off (need to use 128 and then subtract one), but for 4 ticks (or 10 or whatever) these numbers should work out perfectly.
