sidechaining compressors work well for me and i know how to do that. However, when i'm using any other effect, it doesn't seem to work. i'm using one of traktors 12's filter for example, and i slap that on a loop on the sound level. i then add a guitar on another sound slot. I set the sidechain input on the loop to my guitar channel and change the gain and don't notice any difference. i expected the filter to be less noticeable as the guitar plays so the effect ducks underneath it. is that conceptually correct?
