TWChoose randomly select one of several inputs

An output is selected randomly on recieving a trigger from an array of inputs.

the weights of this choice are determined from the weights array.

If normalize is set to 1 the weights are continuously normalized (this is an extra overhead)

when using fixed values the normalizeSum method can be used to normalize the values

superclass: Object (TWChoose is a composite of TWindex and Select )

*ar(trig,array,weights,normalize)

*kr(trig,array,weights,normalize)

(

{

var a;

a = [

SinOsc.ar,

Saw.ar,

Pulse.ar

];

TWChoose.ar(Dust.ar(MouseX.kr(1, 1000, 1)), a, [0.99, 0.05, 0.05].normalizeSum) * 0.2

}.play;

)

Note: all the ugens are continously running. This may not be the most efficient way if each input is cpu-expensive.
