Yes, it's gone then. But so are messages. Btw.: the [tabsend~] and
[tabreceive~] objects directly operate on the sample blocks we're
talking about here, as does the [print~] object, so if you want to see
or influence what's happening in a block, use these.

You mean "window" as in for example a FFT? Yes, that is equivalent to the
block in Pd.
