diki you are correct voice pitch correction/moddelling is only available as an option on the PA1x/pro.....actually there was a thread on the SOS forum i think it was where billy joel apparently sang the anthem with auto tune at the super bowl??? i think it was....anyhoo you should have read the many posts that derided him for doing so, saying they would prefer something a little "off-key" than the results coming out of the auto-tune box.....FWIW i used to own a PA1Xpro and bought the pitch correction option, and used it exactly.....0!!!! used the voice modelling once at a party!!biggest waste of $300 ever...
cheers
