Wrangling the Wily Multi-Track

B4 is an interesting beast, in that any given preset doesn't just contain one sound. The B4 provides upper keyboard, lower keyboard, and foot switch. Each can have its own setting, meaning it can produce three different sounds simultaneously, but in some cases all three of those sounds depend on certain settings (rotator speed, brake, reverb, and drive for instance).

Unless I'm missing something (and I hope I am), the modern sequencer (e.g. Live) is adapted for one plug-in per track, which means one input per plug-in, which means two thirds of B4's potential is never realized, or much harder to coordinate.

So how would I go about routing three tracks worth of data to one plug-in?
