I would say even with 256 oscillators, you could make a fairly nice 
polyphonic additive synth.  If the fundamental freq is 200Hz, the 64th 
overtone would be 12800 Hz, which I would think would be quite 
adequate.  So 256 oscilators would give you 4 voice poly...and I would be 
willing to bet that 1024 oscillators would be no problem, and that would 
make 16 voices.  An additive synth in an XC3S400 would not be probably more 
than a hiccup.... :-)

hic...hic...hic....
