I sent a note to Yamaha about the pitch correction software deonstrated by Craig Knudsen on Youtube... Below is the answer

Hi Ron,

Regarding your TYROS4,
The software demonstrated in the video is a development by one of our consultants. It's not a modification of the Tyros4 operating system and it's not a beta version of a future Tyros4 operating system. We don't have any details other than that at this time.

Please note that the Tyros 4 does have onboard pitch correction as part of its Vocal Harmony 2 processor.

I hope this information is useful. Please let me know if I can help further.

Best regards,
