Applying FX To Samples

Is there a way to apply FXs to samples using the knobs at the top of the DDJ RZ.  I figured out how to use colour FX but I'd like to do a bit more with the samples I have with regards to FX. 

Yes you can, took me ages to find the solution.

At the top of the screen in rekordbox to the left of the 3 FX panels there are 6 squares.

1,2,3,4,S & M. press on S for it to light up and that sides effects will now effect the samples. 

I have a DDJ RX so have to use the laptop to activate. Not sure if there is a hardware way of activating on the RZ. 

How do you activate the Colour FX for samples, That I haven't worked out lol
