Big house in north Raleigh with a mini-concert hall containing 4
concert grand pianos rigged with their hardware & connected to laptops
- I got to basically sit in a room and hear Rachmaninoff, Glenn Gould
and Art Tatum play piano live.  Read this review for a better
explanation of what they do than I can give...

What really made my jaw drop to the floor was the demo of their new
"upright bass" - a thing that looks like "V...GER" from the first Star
Trek movie (geek check) and was made by somebody in Germany.  They
played me an old Oscar Peterson recording with the piano & drums in a
pair of Magnepans and the bass separately reproduced on the gadget -
if you didn't look you'd bet money that Ray Brown was standing there
playing bass.

Fun stuff.  They told me sax & drums are next.  When they figure out
how to do this with acoustic guitar, I want to hear Robert Johnson.
