automation not working

Having trouble with LMMS? Ask about it here.
i sent three triple oscillators in the BB editor to FX8.
then i added pitch shifter to FX8.
i put the BB and an automation track in the first bar, and i tried to automate the rate of the pitch shifter.
i was able to draw the automation but i don't hear any changes nor is the controller moving.

what did i do wrong why can't i change the pitch?
Is the automation in the song or the bb-track? If you put the automation in the song and play the bb-track from the bb-editor, the automation obviously won't play. If you put the automation directly in the bb-editor, it should play every time you play the bb-track, no matter if you play it from the song or the bb-editor.

Remember also to connect the automation to the knob.
