Hey Steve 
I found only the post, you can see above. But in this solution, theres a limitation of the endless knob. Because, wenn I reach for example value 0, I cant continue the move.
The other example, where the other guy, shared his script, it`s a nice one, with reset the value after reaching the values 0 or 127. But then it go laggy.
I cant find another post, where I can make the easiest solution, with the example, Ive tried to explain. As with the fixed centeres position from the values 3F/4E or something like that.
When I move knob left, the value stays on value 3F (63) but triggered everytime this value to keystroke UP, by moving. Same to moving knob right, which stays on value 4E (65) and triggers everytime this value and keytroke DOWN, by moving. When I don`t move the knob, it stays on the centered value (64)
Would be great, to get the example for this small but very effective translation
best regards
