Description::
|
||
|
|
Returns the minimum difference of two values in modulo arithmetics. On a circle, there are two distances between two points. This UGen returns the smaller value of the two.

code::
|
||
|
|
{ var a = Line.ar(0, 4, 0.01), d = ModDif.ar(a); [a, d] }.plot;
|
||
|
|
{ var a = Line.ar(0, 4, 0.01); ModDif.ar(a, 0, (1..4)) }.plot;
|
||
|
|
{ var a = Line.ar(0, 4, 0.01); ModDif.ar(a, (0, 0.25 .. 1), 1) }.plot;
