[PD] is it wise to to have a smaller blocksize in a subwindow?

[Andreas Sumerauer]

I am playing around with IIR filters and I would like to know if it 
makes any sense if the blocksize in the parent window is bigger than 
that of the subwindow. I assume that the Blockwise calculation anyway  
can't be done properly because the subpatch always breaks the mold.
Is there still a reason to keep the bigger blocksize? (for waveguide 
synthesizers, where the filter is used in a feedback path)

Thanks

Andreas
