7 Generally a strong::proxy:: is a placeholder for something. A node proxy is a placeholder for something strong::playing on a server:: that writes to a limited number of busses (e.g. a synth or an event stream). 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: link::Overviews/JITLib::
9 When accessed, ProxySpace returns a link::Classes/NodeProxy::. A similar class without environment: link::Classes/Ndef::
11 For more examples see: link::Tutorials/JITLib/proxyspace_examples::, link::Tutorials/JITLib/jitlib_basic_concepts_01::
13 For GUI overview, see link::Classes/ProxyMixer::. See link::Classes/NodeProxy:: for many relevant methods.
15 subsection::First Example
21 p.fadeTime = 2; // fadeTime specifies crossfade
23 p[\out] = { SinOsc.ar([350, 351.3], 0, 0.2) };
24 p[\out] = { Pulse.ar([350, 351.3] / 4, 0.4) * 0.2 };
25 p[\out] = Pbind(\dur, 0.03, \freq, Pbrown(0, 1, 0.1, inf).linexp(0, 1, 200, 350));
27 p[\out] = { Ringz.ar(p[\in].ar, [350, 351.3] * 8, 0.2) * 4 };
28 p[\in] = { Impulse.ar([5, 7]/2, [0, 0.5]) };
30 a.clear(3); // clear after 3 seconds
43 a link::Classes/Server:: object. Note that on remote computers the clock must be in sync.
46 a link::Classes/Symbol::. If a name is given, the proxy space is strong::stored:: in code::ProxySpace.all:: under this name.
49 for event-based or beat-sync playing use a link::Classes/TempoClock::.
52 replace the currentEnvironment with a new ProxySpace and strong::clear:: the current one, if it is a ProxySpace (this is to avoid piling up proxy spaces).
54 In order to move to another ProxySpace while keeping the current, use strong::pop:: and then strong::push:: a new one. To have multiple levels of proxy spaces, use strong::.new.push;::
57 restore the previous currentEnvironment
60 clear all registered spaces
64 subsection::Play back and access
67 returns a group that plays the link::Classes/NodeProxy:: at that strong::key::.
70 a link::Classes/Symbol::
76 play this number of channels.
79 returns a link::Classes/RecNodeProxy:: that records the NodeProxy at that key.
82 returns a NodeProxy output that plays the NodeProxy at that key, to be used within a function used as input to a node proxy
85 when the proxyspace is created without a running server this method can be used. To run it (internally this is done by link::#-play:: as well).
88 set the fadetime of all proxies as well as the default fade time
91 set the clock of all proxies as well as the default clock.
94 set the quant of all proxies as well as the default quant.
97 free all proxies (i.e. free also the groups, do not stop the monitors)
100 release all proxies (i.e. keep the groups running)
103 stop all proxies (stop only monitors, do not stop synths)
106 end all proxies (free and stop the monitors)
109 clear the node proxy and remove it from the environment. this frees all buses. If a fadeTime is given, first fade out, then clear.
112 add the ProxySpace to the repository (name required)
115 remove the ProxySpace from the repository
117 subsection::Setting the sources
119 The strong::rate:: and strong::numChannels:: of the link::Classes/NodeProxy:: determined in a lazy way from the first object put into this environment (see helpfile). Once it is created it can only be set to a function that returns the same rate and a number of channels equal to the intial one or smaller. For details, see link::Tutorials/JITLib/the_lazy_proxy::.
122 Gets the NodeProxy at strong::key:: (if none exists, returns a new one) and sets its source to strong::obj::. For how this works, see also link::Classes/LazyEnvir:: and link::Classes/NodeProxy::.
125 Return the proxy source object at that key.
127 subsection::"garbage collecting"
130 free and remove all proxies that are not needed in order to play the ones passed in with 'exclude'. if none are passed in, all proxies that are monitoring (with the .play message) are kept as well as their parents etc.
133 free all proxies that are not needed in order to play the ones passed in with 'to'. if none are passed in, all proxies that are monitored (with the play message) are kept as well as their parents etc.
138 creates a new document with the current proxyspace state. This does not allow open functions as proxy sources. see: link::Tutorials/JITLib/jitlib_asCompileString::.
