Side-chain compression not working! please help...

Question

I am trying to duck my es1 bass sound via the kick drum being emitted by an ultrabeat.
i have done the following after reading several guides;
ultrabeat in track 9. es 1 in track 10.
set up basic 4/4 beat purely for learning this method, set es1 to emit one long bass note. after this i put a standard compressor into track 10. pressed sidechain, clicked track9. clicked auto- gain off. set attack to nearly o. release quite short. ratio of 3 ish.
yet the gain reduction meter does not even move. its clearly not picking up any signal whatsoever...
As soon as i put "none" in the sidechain box it starts to work again, so its really baffling.
i am really frustrated by this as it is essential for me to get a clean low end sound yet this method simply won't work for me, any help would be much appreciated!
thank you.

Set the "output" of your kick audio instrument to Bus X. Set the output of Bus X to be Output 1&2. You will only hear one copy of the kick, which flows from:
Audio Instrument -> Bus X -> Output 1&2.
If you use a send instead to send to Bus X, then yes, set it's output to "No Output" as you are already sending the kick to the main output from its own channel.
