[Solved] sidechain issue

thornton
no sir I am saying when I route audio to the sidechain plugin from a send or output of the track. the signal does not pass through the sidechain plug. ( i.e if I choose the prochannel gate choose sidechain (on bus track) no signal.

If I understand you correctly...the signal providing the sidechain input is a control signal only, so it will not be heard in the output.
 
For example suppose you have a sustained guitar power chord going into a gate, with a kick drum for the sidechain signal. The gate will open when the kick hits, and let through the guitar. When the kick goes away, so does the guitar until another kick hits. You will not hear the kick throughout any of this.
