dB-Audioware Sidechain Gate v2.0.0 WiN | 4.7 MbSidechain 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).
