SC3 Tank Reverb (JMC)

Excellent sounding reverb, courtesy JMC:

SynthDef("tank", { arg outbus, feedback=0.9,something=0.1;
		var local, in, amp;
		in = In.ar(outbus);

		amp = Amplitude.kr(Mix.ar(in));
		in = in * (amp > 0.04); // noise gate
		in = in * 0.4;
	
		local = LocalIn.ar(2) * feedback;
		local = OnePole.ar(local, something);
		local = Rotate2.ar(local[0], local[1], 0.237);
		local = AllpassN.ar(local, 0.05, {Rand(0.01,0.05)}.dup, 2);
		local = DelayN.ar(local, 0.3, {Rand(0.15,0.33)}.dup);
		local = AllpassN.ar(local, 0.15, {Rand(0.03,0.15)}.dup, 2);
		local = LeakDC.ar(local);	   
		local = local + in;
		4.do {
				var t;
				t = {Rand(0.005,0.02)}.dup;
				local = AllpassN.ar(local, t, t, 1);
		};
	
		LocalOut.ar(local);
		ReplaceOut.ar(outbus, local);
}).load(s);
