Casio CZ/ VZ/ FZ - Pro Series

I checked the manual- and you can indeed modulate 4 in equal amounts 
by 1,2, & 3 at the same time.

Those links make my head spin (as did the Phase equations in john 
Cownings patent when I first read them years ago).

Summa- I'm a bit surprised that you present different info on the DAC 
resolution of the DX series. I pride myself on providing uesful and 
accurate information. If i'm wrong, I'd sure like to know.

Can you confirm your source of the TX81z being 16 bit ?
