Sidechain Compressor is a flexible VST/AU compressor plug-in. It can be used as a regular channel strip compressor for clean crisp compression & limiting across a wide range of mixing jobs (e.g. adding punch to drum tracks or presence to vocals). For additional flexibility, the sidechain controls (Lo Cut/Hi Cut/Shape) let you customise the compression response.

Sidechain Gate lets you perform clever mixing techniques, by using a source track to gate a destination track. For example, you can use a complex hi-hat pattern in one track to rhythmically gate a synth pad in another track. Or simplify a busy bass guitar by gating it from a kick drum track (so the bass guitar is only heard when the kick drum sounds).
