[PD] outputting samples

[marius schebella]

sorry, i cannot catch what your problem is
the outlet~ of the 256-window produces a stream. one 256-sample vector
covers 5,8 ms (at 44,1 kHz). and the 64-window gets that stream and handles
it in 4 parts (each 64 samples, each 1.45 ms). there is no loop at all.
in each (block)window there is a kind of "trigger-point" until then all
calculations of a vector have to be done. and at that point the result is
copied to what ever (eg. the soundcard). in a 64 block this is done all 1,45
ms (depending on the samplerate). a larger blocksize has less of those
"trigger-points" and does calculations on larger data. - at least that´s how
I understand the whole thing.
sme.
