ouch, i missed the [* 1e-05].
so your rate is really low, lower than sr.
when i change the tabsize to something small (like 44), and the input
signal to something more predicatable ([sig~ 0.5]) the pattern looks
very nice, with samples alternating between 0 and non-0 (0.5 in my
case); every know and then a sample is repeated (e.g. two times 0.5,
then continuing with 0, 0.5,...) but this is expected if your
toggle-rate is not a multiple of your sr.
