class:: BusPlug
summary:: a listener on a bus
categories:: Libraries>JITLib>NodeProxy
related:: Classes/Bus

description::
BusPlug is mainly in use as a basic superclass of NodeProxy, but it can be applied for other things as well. Most methods are documented in the link::Classes/NodeProxy:: helpfile.

ClassMethods::

method::new
Create a new (neutral) instance on the given server

method::audio
Create a new audio rate instance on the given server

method::control
Create a new audio rate instance on the given server

InstanceMethods::

method::clear
Free the bus, end the monitor

method::ar, kr
Return a link to my output, which is limited by strong::numChannels::. If uninitialized, creates a matching bus. Normally, strong::ar defaults to stereo, kr to mono::. This can be set in the classvars: link::#*defaultNumAudio::, link::#*defaultNumControl::

method::play
Plays from a bus index ( strong::out:: ) with a number of channels to another index with a number of channels, within a strong::group:: (ie a target group or server).

argument::out
bus index

argument::numChannels
an link::Classes/Integer::

argument::group
target link::Classes/Group:: or link::Classes/Server::

argument::multi
keep old links and add new one

argument::vol
volume at which to monitor

argument::fadeTime
fade in fade out time

argument:: addAction

method::playN

argument::outs
array of destination channels

argument::amps
array of amplitudes for each channel

argument::ins
array of source channels

argument:: vol
argument:: fadetime
argument:: group
argument:: addAction

method::monitor
returns the current monitor (see link::Classes/Monitor::)

Examples::

code::
// using as a control bus listener

s.boot;
z = Bus.control(s, 16);
a = BusPlug.for(z);

m = { Mix(SinOsc.ar(a.kr(16), 0, 0.1)) }.play;

z.setn(Array.rand(16, 300, 320).put(16.rand, rrand(500, 1000)));
z.setn(Array.rand(16, 300, 320).put(16.rand, rrand(500, 1000)));
z.setn(Array.rand(16, 300, 320).put(16.rand, rrand(500, 1000)));

m.free;


m = { SinOsc.ar(a.kr(2, MouseX.kr(0, 19)), 0, 0.1) }.play; // modulate channel offset

z.setn(Array.rand(16, 300, 1320).put(16.rand, rrand(500, 1000)));


m.free; z.free;

// using as a audio monitor

p = BusPlug.audio(s,2);
d = { Out.ar(p.index, PinkNoise.ar([0.1, 0.1])) }.play;


p.play; // monitor whatever plays in p (the execution order does not matter)



d.free;
d = { Out.ar(p.index, PinkNoise.ar([0.1, 0.1])) }.play;

p.stop;
p.play;

// also p can play to another bus:

p.stop;
p.play(12);

// listen to that bus for a test:
x = { InFeedback.ar(12,2) }.play;
x.free;
