FX-Max or Cubase's System Link (I've never tried system link, but apparently it's meant for those sort of things, it's a built in feature in Cubase.)

yeah i would defenetely go for the fx teleport option. but i heard sometimes it doesnt work well, but its worth cheking. theres also the old fashion way sync via midi time clock or time code, just have to get two midi and audio interfaces, preferely with digital in/out.
cheers
