SendReply should be sent?

1

I have this code, and actually two questions.

SendReply.ar(In.ar(trigBus) > 0.01, "/trg", [40, In.ar(trigBus) , buf]);

  1. If found this trg was being called by looking at a network trace. Converting the hex values to float I saw [40, 0.00625, 10]. Why did this send the reply when 0.00625 > 0.01 is false?

  2. I was initializing trigBus = -1. Not sure why, but it was seeing this noise, for instance 0.00625. I changed to 9999, which seems to prevent it from sending anything, but is -1 a problem?

-1 is not a problem, but it seems to suggest it triggers when the signal changes from non-positive to positive, besides the > operator you wrote

I the value of In.ar(trigBus) is 0.00625, should it have triggered? If so why?

It’s a bit strange, indeed.

5 
{
	var trig = Impulse.ar(0);
	Out.ar(0, DC.ar(1));
	In.ar(-1, 1).poll(trig);
	FreeSelf.kr(A2K.kr(trig));
	Silent.ar(1)
}.play;

// prints:
UGen(OutputProxy): 1

And if you remove the Out.ar(0, DC.ar(1));, it prints 0.

This means that In.ar(-1, 1) is reading bus 0 instead. So initializing trigBus to -1 is not a safe way to deactivate triggering. I think you would need something like:

var trig = Select.ar(trigBus < 0, [In.ar(trigBus), DC.ar(0)]);

I can’t see why it’s triggering for 0.00625 though.
