class:: TExpRand
summary:: Triggered exponential random number generator.
related:: Classes/ExpRand, Classes/IRand, Classes/LinRand, Classes/NRand, Classes/Rand, Classes/TIRand, Classes/TRand
categories:: UGens>Random, UGens>Triggers
Description::
Generates a random float value in exponential distribution from
code::lo:: to code::hi:: each time the
trigger signal changes from nonpositive to positive values
code::lo:: and code::hi:: must both have
the same sign and be non-zero.
classmethods::
method::ar, kr
argument::lo
Lower limit of the output range.
argument::hi
Upper limit of the output range.
argument::trig
The trigger. Trigger can be any signal. A trigger happens when
the signal changes from non-positive to positive.
Examples::
code::
(
{
var trig = Dust.kr(10);
SinOsc.ar(
TExpRand.kr(300.0, 3000.0, trig)
) * 0.1
}.play;
)
(
{
var trig = Dust.ar(MouseX.kr(1, 8000, 1));
SinOsc.ar(
TExpRand.ar(300.0, 3000.0, trig)
) * 0.1
}.play;
)
