Sometimes you may have to disable fast generation of RealTracks, invoke the DXi synth (VSC DXi is the one I did) and then, reboot the computer.

Re-enable the fast generation of RealTracks, disable the DXi synth and then reboot again.

And then, it works as it should.

Why?

I dunno.

But you might give that a shot if all else fails.
