All midi CC values are a range from 0 t0 127 for all synths. (For 7-bit midi.)
On/off buttons use 0 for off and 127 for on.
Broad range knobs go from 0 to 127.
Knobs or buttons with a set number of options have their options divided equally between 0 and 127. Just divide 128 by the number of options and use that value to find the ranges.
If a knob has four options: 128/4=32 <- then the ranges are 0-31, 32-63, 64-95, 96-127
If a knob has five options: 128/5=25.6 <- not an even number so the ranges are 0-24, 25-49, 50-74, 75-99, 100-127 (you may have to tweak the boundary numbers +/- 1 but that's the general idea. It's not hard to figure out.)
From page 48 in the manual.
• Buttons that control “on/off” functions have a Controller value of “0”
at the “off” position and a value of “127” at the “on” position.
• Buttons that step through various possibilities start with a Controller
value of “0” for the “lowest” setting and then increment for each step
upwards. The size of the increments depends on how many possible
settings there are.
