2.1.6. Sidechain

---

The sidechain toggle allows you to enable/disable sidechain processing. When enabled, the source signal will come from the plug-in’s sidechain channel(s). This allows you to drive compression/expansion using an external source, which can be used for example to duck the sidechain signal.

Since this compressor is capable of both compression and expansion, the reverse of ducking is also possible (source amplifies in response to sidechain signal above threshold).
