Can't find any thing on the forums as a step by step on how to get the sidechain sound using the SX. Someone help please

first lower the volume of all your samples (exept the drums) to roughly half the vol of the drums.
then apply the compressor (12) effect to every pad by holding the remain button and pressing the mx?(whatever the multi effect pad button is)
then turn the sustain knob to full
the attack knob to about middle,
then the last knob to full,
then basically muck around to fine tune the sound as this is a rough guide
