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)
