putting a [block~ 128 2] anywhere in your canvas will make it use signal
vectors of 128 samples length with an overlap factor of 2 (read: the
last 64 samples of the old signal vector are the same as the first 64
samples of the new one).
the objects themselves are not notified of this, they just get 128
sample chunks to process. inspecting the signal-vector's samplerate
(sic!, it's really a data-rate) will reveal that it has now the double
samplerate as when using [block~ 128].
