More exactly: DCW function changes the speed how the wave is read
from the memory, thus creating phase distortion, which in effect
changes harmonic content and simulates LPF. That's the reason why
they called this type of synthesis PD - Phase Distortion. It's in
fact very similar to Yamaha DX7, which also works with phase
distortion (FM is additional).

There are even some hidden waves in CZ synths, not normally
accessible. Look here http://homepage.mac.com/synth_seal/html/cz1.html

VZ1 synth and others were even better, they used more elaborated iPD
system with more complex structure.
