Sidechaining in Cubase SX

Here is a nice tutorial video about how to do sidechaining in Cubase SX. As you will see it's a pain to set it up, but after doing it a couple of times it's ok. Well, except you use something like the old TC Electronic Native Bundle or dB-D dynamics processor (watch latency of compression when using these!). I wish Cubase SX had a better sidechain concept.
