1 class:: TIRand
2 summary:: Triggered integer random number generator.
3 related:: Classes/ExpRand, Classes/IRand, Classes/LinRand, Classes/NRand, Classes/Rand, Classes/TExpRand, Classes/TRand
4 categories:: UGens>Random, UGens>Triggers
7 Description::
9 Generates a random integer value in uniform distribution from
10 code::lo::  to  code::hi::  each time the
11 trigger signal changes from nonpositive to positive values.
14 classmethods::
16 method::ar, kr
18 argument::lo
19 Lower limit of the output range.
21 argument::hi
22 Upper limit of the output range.
24 argument::trig
26 The trigger. Trigger can be any signal. A trigger happens when
27 the signal changes from non-positive to positive.

38         outBus = TIRand.kr(0, 1, trig); //play on random channel between 0 and 1
39         Out.ar(outBus, PinkNoise.ar(0.2))
