class:: ReplaceOut
summary:: Send signal to a bus, overwriting previous contents.
related:: Classes/OffsetOut, Classes/Out, Classes/XOut
categories::  UGens>InOut


Description::
link::Classes/Out::  adds it's output to a given bus, making it
available to all nodes later in the node tree (See Synth and
Order-of-execution for more information). ReplaceOut overwrites those
contents. This can make it useful for processing.


See the link::Reference/Server-Architecture:: and link::Classes/Bus:: helpfiles for more information on
buses and how they are used.


classmethods::

method::ar, kr

argument::bus

The index of the bus to write out to. The lowest numbers are
written to the audio hardware.


argument::channelsArray

An Array of channels or single output to write out. You cannot
change the size of this once a SynthDef has been built.


Examples::

code::

(
SynthDef("ReplaceOutHelp", { arg out=0, freq=440;
	var source;
		source = SinOsc.ar(freq, 0, 0.1);

		// write to the bus, replacing previous contents
		ReplaceOut.ar(out, source);

}).send(s);
)

// each Synth replaces the output of the previous one
x = Synth.tail(s, "ReplaceOutHelp", [\freq, 500]);
y = Synth.tail(s, "ReplaceOutHelp", [\freq, 600]);
z = Synth.tail(s, "ReplaceOutHelp", [\freq, 700]);

// release them in reverse order; the older Synths are still there.
z.free;
y.free;
x.free;
