I said it likely wasn't "feasible" not that it was impossible. 
Even the high end digital effects units in the mid 90s only 
managed a handful of basic effects at the same time, and they 
usually did that by using multiple chips, with different chips 
handling different blocks in the chain. A phase vocoder would 
have been pretty hard to pull off on that kind of hardware even 
if it was possible to a level of quality that was useful. I mean 
it's basically fft-->processing-->ifft, which is an order of 
magnitude or two more than the 20 or 30 cycles/sample you need to 
implement a reasonable quality chorus, phaser or eq, etc... Which 
is likely why AutoTune appeared first as a DAW plugin.
