SuperCollider CLASSES

# Out

Write a signal to a bus.
Source: /usr/local/share/SuperCollider/SCClassLibrary/Common/Audio/InOut.sc
Subclasses: OffsetOut, ReplaceOut

## Description

Write a signal to a bus.

Note that using the Bus class to allocate a multichannel bus simply reserves a series of adjacent bus indices with the Server object's bus allocators. abus.index simply returns the first of those indices. When using a Bus with an In or Out UGen there is nothing to stop you from reading to or writing from a larger range, or from hardcoding to a bus that has been allocated. You are responsible for making sure that the number of channels match and that there are no conflicts.

NOTE: Out is subject to control rate jitter. Where sample accurate output is needed, use OffsetOut .

See the Server Architecture and Bus helpfiles for more information on buses and how they are used.

## Class Methods

### *kr (bus, channelsArray)

#### Arguments:

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

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

// write to the bus, adding to previous contents
Out.ar(out, source);

}).send(s);
)

Synth("help-out", [\freq, 500]);
Synth("help-out", [\freq, 600]);
Synth("help-out", [\freq, 700]);
