I'm a little surprised at Mac's response as it takes a somewhat narrow view of the utility of such a capability. BIAB serves, among many other things, as an excellent and highly sophisticated metronome, but for performance it would be very useful to have an intelligent accompanist. As far as I know there is nothing commercially available, but software responsive to the artist does exist in the Media Lab at MIT. I've seen it working as a virtual piano accompanist to a violin soloist. In the demonstration it followed tempo changes and pauses.

This was many years ago. It might be worth contacting the Media Lab to find out what happened to the project. There might be a small technology company somewhere in Massachusetts with an unusual software package available . . .

Edited to add: I wrote my reply before I noticed the link to the video, which I haven't watched yet. If HCE looks like it will do what you want at a reasonable price, I'd say go for it.
