3D sound..

Here a nice video about a revolutionairy 3D sound development system...



But how about integrating 3D sound in our keyboards?
Current technollogy allows incredible surround sound from 3D sound bars or even trough headphones.
Wouldnt it be great to sit behind your piano and sound it like sitting behind a grand piano, while hearing a small accompaniment by a quartetbof jazz musicians from behind your back

When will we fully realize that 3D sound will make the music come alive..
And will this work on gigs, with multiple speaker setups?

Currently the only instrument i know that supports 3d sound is the roland integra 7..
