Pd's oscillator wave tables are 512 samples.  Supercollider uses 8192 - not sure what CSound uses.  The efficiency of the SC code allows for large sample tables and bigger FFTs, which certainly help make a 'smoother' sound. 

It would be interesting to hear what happens with 16x larger tables in Pd.

PS - Amazing that Andy Moorer replied to the blog about the SC version!

Yep I did that as an exercise way back. Lost the code
and wavs now sorry to say :(

But, yes it did show up the weakness of Pd oscils
when compared to Csound - somewhat muddier, with
a slight distortion when using so many.

IIRC its a saw/string like wave and I made it
bandlimited by filling tables and felt very
confident it couldn't be aliasing because
I calculated no sweeps put any harmonics even
close to Nyquist. So, he difference tis kinda
to do with the small table size or interpolation
in Pd I think. Of course in Csound it sounds
gorgeous.
