Madeon says on the Cableguys website: "VolumeShaper is my most used plugin — I have an instance on practically every channel of every song I produce, for sidechaining using MIDI triggers. The curve system allows for quick, precise and smooth envelope creation. It's definitely the most powerful and versatile option I could find for sidechaining purposes." — Madeon on sidechaining his tracks (source [here](http://www.cableguys.com/volume-shaper.html))more
This is my go to sidechain plug. I use it on anything from synths to the kick drum (using an inverted envelope). It allows you to get the precise envelope you're looking for when shaping your sounds.
When adjusting character of my kicks, the Volume Shaper 4 proves to be the solution for me.
I can adjust the character in different bands. So if i want the lows to be more dynamic and i want the mids and highs to be intact, i can separate the kick in different bands and adjust the character from there.
Honestly it beats the c*** out of Nicky's "Kickstart" and also the "LFOTOOL"
