I thought the sidechain was only internal for the EQ. But reading the specs on their site it states:
"Channel Dynamics includes fully featured 2 Band side chain EQ which can also be used in signal path
I'm taking this means you can use an external signal. The plus side is that I own a powercore and wouldn't mind adding this to it. Will download the demo and check it out.
