Singletons (values) inside Lemur are always on a range of 0 - 1 regardless the actual midi mapping....
the location of ball of a multiball object is defined by TWO values - X and Y
To place a ball of a multiball object to the center for example you need to type:
Multiball.x = 0.5;
Multiball.y = 0.5;
If you have more than ONE ball in a multiball object you access each ball the same way you do with all multi-enabled objects of Lemur (sliders, pads, switches) meaning that their x,y,z form vectors (arrays)
so for example if you have 3 balls you access them with x[0], y[0] - x[1], y[1] - x[2], y[2]
so to set three balls to locations - lets say, center, top left corner, bottom right corner you go:
