NdefPreset | SuperCollider 3.13.0 Help

Description

Like ProxyPreset, NdefPreset stores settings and can morph between them.// same example as in link::Classes/ProxyPreset:: but using Ndef for Tdef: ( // make an empty Tdef a = Tdef(\a); // give it some param settings a.set(\dt, 0.1, \freq, 440, \bend, 4, \bendVar, 4, \sustain, 0.05); // add specs for the params to the Tdef - see Halo class. a.addSpec(\dt, [0.03, 3, \exp]); a.addSpec(\bend, [-24, 24, \lin]); a.addSpec(\bendVar, [-24, 24, \lin]); a.addSpec(\sustain, [0.003, 3, \exp]); // define what the Tdef does Tdef(\a, { |env| loop({ ( instrument: \pingbend, freq: env[\freq], bend: env[\bend] + env[\bendVar].rand2, sustain: env[\sustain], pan: 1.0.rand2 ).play; env[\dt].wait; }) }); Tdef(\a).gui; // will be using this SynthDef: s.boot; SynthDef(\pingbend, { arg out=0, freq=440, bend = 4, sustain=0.05; var env = EnvGen.ar(Env.perc(0.001, sustain, 0.3), doneAction:2); freq = freq * XLine.kr(1, bend.midiratio, sustain); Out.ar(out, SinOsc.ar(freq, 0, env)) }).add; ) // brain transplant Ndef(\a, { arg freq=440, bend = 4, sustain=0.05, dt = 0.1; var trig = Impulse.ar(1/dt); var env = EnvGen.ar(Env.perc(0.001, sustain, 0.3), trig); freq = freq * EnvGen.ar(Env([1, bend.midiratio], [sustain], \exp), trig); Pan2.ar(SinOsc.ar(freq, 0, env), TRand.ar(-1.0, 1.0, trig)); }); Tdef(\a).envir.keysValuesDo { |k, v| Ndef(\a).set(k, v) }; Ndef(\a).addHalo(\spec, Tdef(\a).getSpec); Ndef(\a).getSpec === Tdef(\a).getSpec; Ndef(\a).play; Ndef(\a).gui; // then make a ProxyPreset for for the Tdef: // for Tdefs, best use TdefPreset. b = NdefPreset(Ndef(\a)); // these are the param names for which settings are stored // they can be reordered, see ParamGui help file. b.namesToStore; // in emergencies: NdefPreset.all.clear; Ndef(\a).addHalo(\namesToStore, Ndef(\a).controlKeys); NdefPreset(Ndef(\a)); // add the current state of the envir as a setting b.addSet(\ada); // make and add 3 random settings ( b.setRand(0.25); b.addSet(\bobo); b.setRand(0.25); b.addSet(\coco); b.someRand(0.25, 0.5); b.addSet(\dad); ) // b.getSetNames; b.settings.printcsAll;""; b.setCurr(b.getSetNames.choose.postln); b.setTarg(b.getSetNames.choose.postln); // a gui for the NdefPreset g = NdefPresetGui(b, 8).moveTo(10, 200); b.morph(1.0.rand, \ada, \coco); b.xfadeTo(\coco, 3, { "xfade doneFunc done.".postln; }); b.xfadeTo(b.getSetNames.choose.postln, exprand(0.3, 10)); // do recursive crossfading ( f = { "next xfade: ".post; b.xfadeTo(b.getSetNames.choose.postln, exprand(0.3, 10), f) }; f.value; ) f = nil; // stop // set relative to a preset: b.getSetNorm(\coco); b.proxy.setUni(*(b.getSetNorm(\curr) + [0.1.rand2]).flat); b.setRelFrom(\coco, { 0.3.rand2 }.dup(b.namesToStore.size))

Class Methods

NdefPreset.all

the global dict for all NdefPreset instances

NdefPreset.proxyClass

the class to be used with NdefPreset: Ndef.

NdefPreset.new(key, namesToStore, settings, specs, morphFuncs)

access an existing NdefPreset or make a new one for a Ndef.

Arguments:

key	If key is key of an existing NdefPreset, then that is accessed. If key is a Ndef, then a net NdefPreset with that Ndef's key will be created.
namesToStore	which paramNames to store in the presets. if none given, inferred from the current proxy settings.
settings	provide preset settings for the proxy
specs	provide preset specs for the proxy, mainly for randomizing and morphing. if none given here, and object has a halo of specs, those in halo will be used.
morphFuncs	special functions to provide for morphing between non-numerical settings. not used yet.
