I wanted to show the difference the side chain makes to the techno sample. I now realise how to side chain and how it works. It works by lowering the frequency of something like the bass just before the kick comes in, so that it does not muddy the two frequencies. The middle section shows the kick and bass without side chain, which is muddy and unclear.
i think compressors (like the one you used here) works by lowering the signal's level and not specific frequencies level (unless is multiband)
