Trig1 | SuperCollider 3.14.0 Help

Description

When a nonpositive to positive transition occurs at the input, Trig1 outputs 1 for the specified duration, otherwise outputs 0.

Class Methods

Trig1.ar(in: 0.0, dur: 0.1)

Trig1.kr(in: 0.0, dur: 0.1)

Arguments:

in	Trigger. Trigger can be any signal. A trigger happens when the signal changes from non-positive to positive.
dur	Duration of the trigger output.

Examples

{ Trig1.ar(Dust.ar(1), 0.2) * FSinOsc.ar(800, 0.5) }.play

To create a fixed duration gate
(

SynthDef("trig1", { |dur = 0.125|
    var gate;
    gate = Trig1.kr(1.0, dur);
    OffsetOut.ar(0,
        SinOsc.ar(800, 0.3)
        * EnvGen.kr(
            Env([0, 0.1, 0.1, 0], [0.01, 1.0, 0.01], [-4, 4], 2),
            gate,
            doneAction: Done.freeSelf)
    )
}).add;

Routine({
    1.0.wait;
    100.do({
        s.sendBundle(0.05, ["s_new", "trig1", -1, 0, 0, 0, rrand(0.02, 0.25)]);
        0.25.wait
    })
}).play(SystemClock)

)

This should sound like a continuous sine wave, although it is actually a series of 0.25 second synths.

        * EnvGen.kr(
