That much (and not a great deal else) has been revealed in the teaser video above, though the moniker suggests that that this could be an instrument that brings together a range of different technologies (sound engines, perhaps?).
We're told that this will be Yamaha's new flagship synth, so speculation is rife that it could be a replacement for the Motif range. That would imply that it'll be digital rather than analogue, and aimed at the higher end of the market.
We'll find out soon enough, as will you if you keep it right here on MusicRadar.
