class:: NodeMap
summary:: store control values and bus mappings
categories:: JITLib>NodeProxy, Server>Nodes, Server>Abstractions
related:: Classes/Bus
description::
Object to store control values and bus mappings independently of a specific node.
code::
a = NodeMap.new;
a.set(\freq, [446, 662], \amp, 0.2, \out, Bus.audio(s));
a.asOSCArgArray;
::
InstanceMethods::
method::set
set arguments of a node
method::unset
remove settings
method::unmap
remove mappings
method::at
return setting at that key.
method::sendToNode
apply a setting to a node by sending a bundle
method::send
apply a setting to a node by sending a bundle
method::addToBundle
add all my messages to the bundle
method::addToEvent
add all my values to the event
method::asOSCArgArray
returns the arguments for an OSC message.
method::unmapArgsToBundle
returns the arguments for an OSC message to unmap any mapped controls.
method::setMsg
returns the OSC message for setting a synth
argument:: target
a group, synth, or server to use as a nodeID to set.
method::get
Kept for backward compatibility.
method::clear
Remove all settings and clear cache
private::updateArgs, upToDate
Examples::
code::
s.boot;
(
SynthDef("modsine",
{ | out, freq=320, amp=0.2 |
Out.ar(out, SinOsc.ar(freq, 0, amp));
}).add;
SynthDef("lfo",
{ | out, rate=2 |
Out.kr(out, LFPulse.kr(rate, 0, 0.1, 0.2))
}).add;
)
// start nodes
(
b = Bus.control(s,1);
x = Synth("modsine");
y = Synth.before(x, "lfo", [\out, b]);
)
// create some node maps
(
h = NodeMap.new;
h.set(\freq, 800);
h.map(\amp, b);
k = NodeMap.new;
k.set(\freq, 400);
k.unmap(\amp);
)
//apply the maps
h.sendToNode(x); // the first time a new bundle is made
k.sendToNode(x);
h.sendToNode(x); // the second time the cache is used
k.sendToNode(x);
h.set(\freq, 600);
h.sendToNode(x); // when a value was changed, a new bundle is made
//free all
x.free; b.free; y.free;
