Yamaha psr vocal harmony, anything similar in software?

I recently sold my Yamaha psr9000 and Tyros 2 and want to recreate the same harmony vocal effect.

Is there anything available in software that reproduces a similar 3 voiced vocal harmony when using a mic?

Did Yamaha release anything like this in software? i'm not interested in vocaloid though, thats a totally different thing altogether. I've tried googling but nothing? I'm almost certain i read something about a software version?

For anyone interested in studio harmony type fx

One hundred

I could do ELO, Clannad and 10cc all at the same time
