Strange CoinGate behavior

Questions
1

Hi all, today I noticed some behavior I can’t explain. When CoinGate is uncommented in the following example, it appears to skip the first trigger, even with 100% probability. This does not happen if the phase of Impulse is somewhere between 0 and 1.

Is this a bug, or am I misunderstanding intended usage?

	var trig;
	trig = Impulse.kr(50);
	// trig = CoinGate.kr(1.0, trig);
}.plot(0.12)

i have discovered something similiar in the past. I think this is an initialisation bug.
You could add Impulse.ar(0) or derive the triggers from phases, which im doing at the moment because of this issue with some Ugens.

(
var rampToTrig = { |phase|
	var history = Delay1.ar(phase);
	var delta = (phase - history);
	var sum = (phase + history);
	var trig = (delta / sum).abs > 0.5;
	Trig1.ar(trig, SampleDur.ir);
};

{
	var rate = 100;
	var phase = (Phasor.ar(0, rate * SampleDur.ir) - SampleDur.ir).wrap(0, 1);
	var trig = rampToTrig.(phase);
	var gate = CoinGate.ar(1.0, trig);
	[phase, gate];
}.plot(0.02);
