4 categories:: UGens>Random, UGens>Triggers
7 Description::
9 Generates a random float value in exponential distribution from
10 code::lo::  to  code::hi::  each time the
11 trigger signal changes from nonpositive to positive values
12 code::lo::  and  code::hi::  must both have
13 the same sign and be non-zero.
16 classmethods::
18 method::ar, kr
20 argument::lo
21 Lower limit of the output range.
23 argument::hi
24 Upper limit of the output range.
26 argument::trig
28 The trigger. Trigger can be any signal. A trigger happens when
29 the signal changes from non-positive to positive.

34 code::
38         var trig = Dust.kr(10);
39         SinOsc.ar(
40                         TExpRand.kr(300.0, 3000.0, trig)
41                 ) * 0.1
42 }.play;
47         var trig = Dust.ar(MouseX.kr(1, 8000, 1));
48         SinOsc.ar(
49                         TExpRand.ar(300.0, 3000.0, trig)
50                 ) * 0.1
