Generally a proxy is a placeholder for something. A node proxy is a placeholder for something playing on a server and writes to a limited number of busses (usually a synth, but also an event stream that makes synths). NodeProxy objects can be replaced and recombined while they play. Also they can be used to build a larger structure which is used and modified later on. Overview: JITLib.
NodeProxy is used internally in ProxySpace and it is a superclass of Ndef, allowing to easily access and combine a large number of placeholders.
Graphical editor for a node proxy: NdefGui.

Return a link to numChannels of my output. If uninitialized, creates a matching bus. Normally, ar defaults to stereo, kr to mono. This can be set in the classvars: *defaultNumAudio, *defaultNumControl
For consistency, it always returns an array of signals when no numChannels are given. To make it a single ugen output, use numChannels = 1 . See also: InBus.
| numChannels |
Number of channels returned. If the receiver is neutral or reshaping is elastic, initialize it to this number. If this is more than the available channels, use the clip behaviour (below). If set to |
| offset |
Channel offset when reading a bus that has more channels than numChannels, cross fading between adjacent channels. |
| clip |
If set to 'wrap', exceeding channels will wrap around, if set to 'clip', repeat the last one. |
Usage: proxyA <-- proxyB. Set proxyA source to proxyB and play proxyA. If proxyB was playing, fade it out. This is convenient in the following situation:
xxxxxxxxxxb = NodeProxy.new.play;b.source = { PinkNoise.ar(0.2.dup) };// now I want to filter b through a new proxy.a = NodeProxy.new;a <-- b; a.source = { HPF.ar(b.ar, 7000) };a.source = { HPF.ar(b.ar, 3000) };// changing the sourcea.clear; b.clear;Chaining. Usage: proxyA <<> proxyB <<> proxyC <<> ... . Map proxyC source to proxyB \in argument, and proxyB to proxyA's in argument.
xxxxxxxxxxa = NodeProxy.new.play;a.source = { RLPF.ar(\in.ar(0!2), [4600, 7000], 0.1) };b = NodeProxy.new.source_ { Impulse.ar([5, 7] / 2) };a <<> b;Inverse of the above. Usage: proxyA <>> proxyB <>> proxyC <>> ... .
NodeProxy keeps a number of slots which can be sources and are mixed on the same bus.. The default source is the slot 0. All objects can be exchanged while running, and also before and after. Normally, the source is active immediately. If sources are to be exchanged "quietly", set the node proxy to sleep (awake = false), or use the message prime().
See the list under section Supported sources
Play a new synth through proxy and release/remove any old ones.
xxxxxxxxxxa = NodeProxy(s);a.play;a.source = { Pulse.ar(130, Saw.kr(0.3)) * 0.1 }; // change this line while running| obj |
can be one of the supported inputs (see Supported sources) NOTE: When reshaping is set, e.g. to \elastic, setting the source can change the number of channels of the proxy. This means that its bus changes, and that child proxies, which read signals from it, may also change. See the example in Routing. |
Signals can be routed between any number of node proxies.
See also: BusPlug: -ar, BusPlug: -value, Reshaping.
Here is a simple example, using Ndef (NodeProxy works similarly):
xxxxxxxxxxNdef(\maus, { MouseX.kr });Ndef(\haus, { Pan2.ar(Blip.ar(Ndef.kr(\maus, 1) * 70), SinOsc.kr(Ndef.ar(\maus, 1) * 5)) }).play;Ndef.kr(\maus) will return an Array. Subsequently, e.g. by a Pan2 UGen, you may get the message:
WARNING: Synth output should be a flat array.
If you intend the output to be really mono, make it explicit by writing: Ndef.kr(\maus, 1)
With elastic reshaping, you can use the parent to expand the child, if you omit the number of channels in the routing:
xxxxxxxxxxNdef(\maus, { MouseX.kr });Ndef(\haus, { Blip.ar(Ndef.kr(\maus) * 70) }).play;Ndef(\haus).reshaping = \elastic;Ndef(\maus).reshaping = \elastic;Ndef(\maus, { LFNoise0.kr(1 ! 8) + 1 }); // now 8 parallel channels of audio are audible.Three parameters are automatically specified if they don't exist in a given UGen function. You can override their use: [\out, \gate, \fadeTime]
If a UGen function that is passed to the proxy has its own envelope, and if this envelope can free the synth, the node proxy uses this envelope instead of making its own. If you provide a fadeTime argument, the proxy's fadeTime will be used.
xxxxxxxxxxNdef(\sound).fadeTime = 3;(Ndef(\sound, { |fadeTime = 1, gate = 1| var e = Env.adsr(fadeTime, 0.01, 0.4, fadeTime).ar(2, gate); SinOsc.ar(100 + (e * 700), SinOsc.ar(208) * (1 - e) * 6) * e * 0.1}).play)copies the hidden internal state to make the new proxy independent of the old, but will keep the reference to the source object. The rendered SynthDef is cached, which makes this method more efficient than simply assigning the same function to a new proxy. By design, the monitor is copied, but is not running (use play to start it in the same configuration).
xxxxxxxxxxa = NodeProxy(s);a.source = { |freq = 444| Blip.ar(freq * [1, 1.03], 200) * 0.1 };a.play;a.set(\freq, 555);b = a.copy;b.play;b.set(\freq, 222);xxxxxxxxxxs.scope(4);a = NodeProxy(s);a.source = { |freq = 234| Blip.ar(freq * [1, 1.03], 20) * 0.5 };a.playN([0, 1, 3], [0.04, 0.3, 0.1], vol: 1); // some complicated routinga.set(\freq, 123);b = NodeProxy(s);b.source = { |freq = 1000| SinOsc.ar(freq * 3 * {{ rrand(0.9, 1.1) }.dup(8) }.dup(2)).mean * 0.5 };b.monitor = a.monitor.copy;b.nodeMap = a.nodeMap.copy;b.play;a.stop;Copy the internal settings of one proxy into another. Old state is cleared.

Determines how to behave when a new source is added. Current options:

xxxxxxxxxxa = NodeProxy(s);a.reshaping = \elastic;a.play(0, 2); // play stereoa.source = { BPF.ar(Dust.ar(8 ! 8), (0..5).nthPrime * 300, 0.01) * 20 };a.numChannels; // 8Adjust the proxy to a given rate / numChannels. If there are any child proxies that have elastic -reshaping, they are adjusted accordingly.

Remove the last object and its synths, if they exist.
Set the source by index. Objects can be inserted at any index, only the order of indices is relevant. Internally, NodeProxy uses an Order to access the sources.

Pause all objects and set proxy to paused
If paused, start all objects
Rebuild all SynthDefs from sources.
Arrange the order of groups from this to the last. This can be important when external input is filtered in order to minimize latency. Note that if a -parentGroup was provided, the nodes must be in the same parentGroup.
Release all running synths and the group. If patterns are playing, stop them.
| fadeTime |
decay time for this action |
| freeGroup |
a boolean |
release running synths. If patterns are playing, stop them.
| fadeTime |

reset everything to nil, neutralizes rate/numChannels
| fadeTime |
if a fadeTime is given, first fade out, then clear. |
Calls a function after the fadeTime and server latency have passed. If the proxy specifies a quant value, the function is evaluated fadeTime + latency seconds after the next timepoint on the quant grid; otherwise, the fade delay begins immediately.
| func |
a function to be called at the appropriate time |
Returns an array of all sources
Returns the first source.
The node proxy's server (a Server).
The node proxy's private bus (a Bus). Because it has a private bus, it is not audible directly - monitoring it by (.play or playN) routes it to the hardware output channels.
The bus rate (default: nil) The rate and number of channels is determined either when the instance is created (.control/.audio) or by lazy initialisation from the first source (see the_lazy_proxy)
The bus numChannels (default: nil)
true if the proxy has no initialized bus.
The node proxy's group (a Group). This is maintained by the proxy and serves as a context in which all synths are placed.
Access the parentGroup (default: nil), which can be set to run the proxy's group in another group. This group has to be maintained (kept playing etc.) externally.
A clock, which can be set to account for different timing schemes, such as beat accurate replacement of sources.
A quant value, to specify quantizes replacement of sources. Compatible with the general use of quant in SuperCollider.
Synchronize the proxies by resending and adjusting to quant.
Access the Monitor object, which plays back the output of the proxy's private bus.
Returns true if the object has been initialized on the server, e.g. a synthDef has been stored.
Returns true if the processes are paused.
If set to false (default: true), a change of the source does not start a new synth immediately. This is useful when synths are triggered by -spawn, and a change of sound should not duplicate sends.

NodeProxy behaves like its NodeMap and very similar to a Synth.
