input error(?) on plugin

hello there.

i think i might be going crazy...

so below is a super tiny plugin that just prints out the input samples that it's given to the message window. i'm just giving the Ugen a static input value of 0.0, yet it reports a value of 8.0000000 on the 5th sample and the 17th sample ... for every block...

can someone tell me whether it's my current build of sc3 that's doing this or am i fudging something in this superbasic plugin?? are you able to reproduce the same effect on your system??

help please. this is driving me nuts...

here's the code i'm using:

// THE PLUGIN //
<x-tad-smaller>
</x-tad-smaller><x-tad-smaller>/*
Adam Overton
TestInput -- Converts an incoming signal into binary, and outputs that binary series (0111000) at audio rate.
Since each single input value will put out 16-32 bits, this ugen only samples the input every N-samples, where N
is equal to the number of bits per input value. Since that may leave out many input samples, the user can specify
which input sample they would like to use, which will be useful when using more than one of these generators at a time...
