summary:: Print the current output value of a demand rate UGen
categories:: UGens>Demand, UGens>Info
description::
Print the current output value of a demand rate UGen.
WARNING:: Printing values from the Server in intensive for the CPU. Poll should be used for debugging purposes. ::
classmethods::
private:: new1
method:: new
argument:: in
ugen to poll values from
argument:: label
a label string
argument:: run
active if 1, inactive if 0. can be a demand ugen (default: 1)
argument:: trigid
discussion::
the print-out is in the form: code:: label: value block offset: offset. ::

examples::
code::
{ Duty.kr(0.5, 0, Dpoll(Dseries(0, 1, inf) * 2)); 0.0 }.play;
// posts only when cursor is in right half of the screen
{ Duty.kr(0.5, 0, Dpoll(Dseries(0, 1, inf) * 2, run: MouseX.kr > 0.5)); 0.0 }.play;
// label
{ LFPulse.ar(Duty.kr(0.5, 0, Dpoll(Dseries(0, 1, inf) % 10 + 1 * 30, "value"))) * 0.1 }.play;
// block offset:
{ Duty.ar(0.511, 0, Dpoll(Dseries(0, 1, inf) * 2)); 0.0 }.play;
// multichannel expansion:
(
{
var x = Duty.kr(0.5, 0,
Dpoll([Dseries(0, 1, inf), Dgeom(1, 1.1, inf)], ["first", "second"])
);
LFPulse.ar(100 + (x * 100)) * 0.1
}.play
)
{ Duty.kr(0.5, 0, Dpoll(( Dseries(0, 1, inf) + _ ).dup, ("value" + _).dup)); 0.0 }.play;
// the message dpoll(label, run, trigid) is a shorthand:
{ Duty.kr(0.5, 0, Dseries(0, 1, inf).dpoll); 0.0 }.play;
{ Duty.ar(0.5, 0, SinOsc.ar(0.1).dpoll); 0.0 }.play;
