Yes ! See Pages 180 to 183 of the PSR-3000 manual for the various Vocal Harmony Parameters. Turn on LEAD PITCH CORRECTION to the "Correct" setting. Not being a singer, I have never used Vocal Harmony on my PSR-3000, so I can not tell you how well it works. Maybe Gary or some of the others can give you some advice on that. I do know that some (many/most/?) of them eventually opted for the TC Helicon Vocal Harmony unit because of its better performance characteristics, but that Vocal Harmony demo that Michel Vonken does on the PSR-2100 has always sounded pretty good to me.
