XCut
+Select one from an array of inputs. When index is changed, fades between the old and new signals using switch-and-ramp technique, minimizing audible artefacts/clicks.
+Class methods
+*ar(inArray, which, envLength, mul, add)
+inArray - array of inputs.
+which - index of the signal to select.
+envLength - length of the x-fading window in samples, (default 2000).
+Examples
+// execute this line first
+b=Buffer.read(s,"sounds/a11wlk01.wav");
+// now, execute this block and click the mouse button to switch between two signals
