Subclassing and Internal Methods

The following methods are usually not used directly or are called by a primitive. Programmers can still call or override these as needed.

Examples

Make a basic editor:( e = Env([1, 2], [10]); w = Window("Env Editor", Rect(200, 200, 300, 200)); v = SCEnvelopeEdit(w, w.view.bounds.moveBy(20, 20).resizeBy(-40, -40), e, 20).resize_(5); w.front; ) v.addBreakPoint; ( v.clear; v.redraw; v; ) v.maxLevel_(2); // to give more headroom v.maxTime_(2); // to increase release point v.minTime_(-1); // to increase attack time e.curves_('sin'); // env object is changed v.refresh; // must refresh editor

Controlling a Synths.boot; ( e = Env([0, 1, 0.7, 0.9, 0], [0.03, 0.03, 0.03, 0.03], 'sin'); f = Env([0, 1, 0.7, 0.9, 0], [0.03, 0.03, 0.03, 0.03], 'sin'); w = Window("Shards", Rect(100, 100, 500, 400)); v = SCEnvelopeEdit(w, w.view.bounds.resizeBy(-20, -200), e, 10).resize_(2); StaticText(w, v.bounds).string_(" amplitude").resize_(2); x = SCEnvelopeEdit(w, v.bounds.moveBy(0, 200), f, 10).resize_(2); StaticText(w, x.bounds).string_(" frequency").resize_(2); w.front; ) ( SynthDef("sineBlip", { arg freq = 440, vol = 0.1, la0, la1, la2, la3, la4, ta0, ta1, ta2, ta3, crva, lf0, lf1, lf2, lf3, lf4, tf0, tf1, tf2, tf3, crvf; var signal, fenv, aenv; fenv = EnvGen.ar(Env([lf0, lf1, lf2, lf3, lf4], [tf0, tf1, tf2, tf3], crvf)); aenv = EnvGen.ar(Env([la0, la1, la2, la3, la4], [ta0, ta1, ta2, ta3], crva), doneAction: Done.freeSelf); signal = SinOsc.ar([freq, freq*2] * fenv) * aenv * vol; Out.ar(0, signal.dup); }).add; ) ( Routine({ var par, indices; indices = (2..21); loop({ par = (indices +++ ( v.env.levels ++ v.env.times ++ v.env.curves ++ x.env.levels ++ x.env.times ++ x.env.curves)).flatten; s.sendBundle(s.latency, [\s_new, "sineBlip", -1, 1, 1, \freq, exprand(4e3,11e3)] ++ par); 0.04.wait; }); }).play; )
