That's really incredible! It looks like the technology is being targeted, for now, at project studios. I would bet that this is going to be a very pricey piece of software for now.

It looks like you could use the tech to just copy a vocal track and then paste harmonies over it. But the vocals they were demoing, had a lot of space. Many vocal harmonies change notes in mid-breath during changing chords.

They showed the technology with guitar and keyboard. It would be interesting to see how it worked with vocal harmonies, strings, organs, and other instruments.
