Some interesting variations on the Goldberg Variations at Michael Century’s Vimeo page.

In this version, performers use a Nintendo wireless controller to modulate dynamics, tempo, and incidence of looping. Computer programmed in Max strictly follows the 32 bar harmonic structure composed by Bach, but it’s possible to jump from variation to variation, in “random mode” (this only occurs rarely in this demo). The “linear mode” proceeds through Bach’s score as composed, though in the demo here it seems the computer sometimes has a mind of its own. Abrupt gestures caused seizures, sometimes with, and sometimes without recovery.

Sort of like a fancypants version of pianola controls, but with the ability to loop at will.
