@section{description}
A general purpose class for monitoring or crosslinking between busses. It supports multichannel expansion and crossfading between settings. It provides optimizations for playing contiguous channels to other contiguous busses (link::#play::) and for more complex routings, such as splitting, spreading etc to multiple channels (link::#playN::). Monitor uses the existing set of link::Classes/SystemSynthDefs:: to do this.

x = Monitor.new; // create a new monitor
x.play(fromIndex: 87, fromNumChannels: 3, toIndex:0, toNumChannels:2); // play them back to the stereo hardware channels

@section{method}
play
Plays from a bus index with a number of channels to another index with a number of channels, within a target group, or a server.
@section{argument}
fromIndex
bus index from which to read
@section{argument}
fromNumChannels
number of channels to read from.
@section{argument}
toIndex
bus index to which to write.
@section{argument}
toNumChannels
number of channels to write. If this number is larger or smaller than fromNumChannels, wrap around. If nothing is given, uses fromNumChannels.
@section{argument}
target
where to send the synths to (default: server default group)
@section{argument}
multi
keep old links and add new one: this allows you to add layer after layer, otherwise free ther previous mapping (false by default).
@section{argument}
volume
volume at which to monitor
@section{argument}
fadeTime
specifies the fade in and fade out time
@section{argument}
addAction
where, relative to the target to place the monitor group.

@section{method}
playN
Plays from an array of bus indices to another array of bus indices with an array of amplitudes, within a target group, or a server.
@section{note}
The arguments strong::out::, strong::amp:: and strong::in:: can be nested arrays. see also link::Reference/playN::
The three arguments out, amp, and in will wrap if they do not have the same size, like this:
@racketblock[ [[0, 1], [0.1], [3, 4, 5]].flop ::
::
]
@section{argument}
out
array of destination channels.
@section{argument}
amp
array of amplitudes for each channel
@section{argument}
in
array of source channels
@section{argument}
vol
global scaling value for amplitudes
@section{argument}
fadeTime
specifies the fade in and fade out time
@section{argument}
target
where to play (default: server default group)
@section{argument}
addAction
where, relative to the target to place the monitor group.
@section{argument}
multi
keep old links and add new one: this allows you to add layer after layer, otherwise free ther previous mapping (false by default).
@racketblock[
// examples: args are // outs, amps, ins, vol, fadeTime

x.playN(
[0, 1, 4], // to these outs
[0.1, 0.4, 0.3], // with these volumes
[87, 88, 89] // from these ins
);
)
(
x.playN(
[0, [1, 3, 2], 4], // outs can be nested: 87 -> 0, 88 -> [1, 3, 2], 89 -> 4
[0.1, [0.4, 0.2, 0.1], 0.3], // with nested volumes 0.1, [0.4, 0.2, 0.1], and 0.3
[87, 88, 89]); // reading from these ins
)
// can also set global volume and fadetime
x.playN(vol: 0.0, fadeTime:4);

@section{method}
stop
Stops within the fadeTime.
@section{note}
this keeps all the settings, so when using
@racketblock[play:: next time, it will play in the same configuration, overriding only values provided.::

@section{argument}
argFadeTime
The time for fading out all routing synths.
@section{method}
clear
Stops within the fadeTime.
@section{note}
unlike
@racketblock[stop::, this removes all the settings.::
]
@section{method}
vol
Set the volume.

Set or get the first output index.
@section{method}
outs
Set or get the array of output bus indices.
@section{method}

Set or get the array of input bus indices.
@section{method}
amps
Set the array of amplitudes.
@section{method}

isPlaying
Returns true if the group is still playing.
@section{method}
group
Return the group in which all mapping synths are running.
@section{method}
numChannels
Return the number of input channels.
@section{method}
copy
Return a copy of the receiver, with the same channel setting, but not running. You can run it with the settings by sending it the link::#play:: message, and pass in any modifications you want to make.
@section{method}
playToBundle
Adds all playing osc messages to a bundle, passed as an argument. The bundle object should implement the method strong::.add::
