So it seems that really, this technology is only a vocoder, as you need to actually PLAY/record the notes for it to pitch shift. It does not work purely on the actual audio...maybe not so revolutionary after all, but an improvement on existing technology...Although it IS Yamaha and that is their way, just improve on what is already available and then spin it out to be some new and revolutionary thing...and of course then charge an arm and a leg for it!!! (Just an observation on Yamaha methods, not a criticism)
