SCEnvelopeEdit

Location: NOT INSTALLED!

Description

An editable Envelope view.

Some Important Issues Regarding SCEnvelopeEdit

The breakpoints are color coded as follows:

blue	normal
red	sustain node
green	loop node

Class Methods

.new

Arguments:

parent	The parent view.
bounds	An instance of Rect, or a Point indicating `width@height`.
env	The envelope. An instance of Env.
pointsPerSegment	The resolution in points per segment. Default value is 10.

.paletteExample

Arguments:

parent
bounds

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:

Controlling a Synth

s.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;
