Examples

    FreeSelf.kr(t_trig);

}).add;

s.sendMsg("/n_set", 1731, \t_trig, 1);

// a single impulse SynthDef:

(
SynthDef("dirac", { arg out, amp=0.1;
    var u;
    u = Impulse.ar(1);
    FreeSelf.kr(u);
    Out.ar(out, u * amp);
        // multiply by amp after using for release, so amp = 0
        // doesn't cause synth buildup.
}).add;
)
