description::
Returns a stream that behaves like an arithmetic series.
ClassMethods::
method::new
argument::start
start value.
argument::step
addition factor.
argument::length
number of values produced.
Examples::
code::
(
var a;
a = Pgeom(1.0, 1.1, inf);
a.asStream.nextN(100).plot;
)
// sound example
(
SynthDef(\help_sinegrain,

var env;
env = EnvGen.kr(Env.perc(0.01, sustain, 0.2), doneAction:2);
Out.ar(out, SinOsc.ar(freq, 0, env))
}).add;
