Many seem to be forgetting that this software clearly is not just simple pitch correction.

That may have been around for years but, this software also turns a flat and uninteresting voice into one with some depth, vibrato and power and gives the impression of a singer with a really good voice.

Take the average bad singer and just use pitch correction and you will still hear a bad singer only in the correct pitch.

If this software can be incorporated into a Tyros4, it will be the first software with all these capabilities to be found in a usable form and in a mass produced keyboard.
