the signal specs are fixed with a canvas.
that is: ALL signals in your subpatch will have a size of 128 samples
and an overlap factor of 2.
if you only consider a single object with one input and one output, this
means that both input and output will have the same length and overlap
factor and samplerate.

overlap-adding is applied at the patch boundaries (e.g. the [outlet~] of
your subpatch to the parent patch running at the nominal specs [block~
64 1].
