s.boot;
SynthDef("a", { Out.ar(0, SinOsc.ar(800, 0, 0.2)) }).send(s);
SynthDef("b", { arg gate=1; Out.ar(1, PinkNoise.ar(0.3)); Pause.kr(gate, 1001); }).send(s);
s.sendMsg(\s_new, \a, 1001, 0, 0);
s.sendMsg(\s_new, \b, 1002, 0, 0);
s.sendMsg(\n_set, 1002, \gate, 0);
s.sendMsg(\n_set, 1002, \gate, 1);
