Designated Sidechain effect with various triggers.

Basically like a grown-up version of autoduck from mobile effects rack that can be triggered by multiple trigger sources, ie. midi, audio, sync.

Sidechaining is huge, there can never be too many methods, but a quick and easy way is very nice. Limiter is great, but not for everything. envelope controller is awesome also, so is peak, fruity compressor is good too, but no visual aid (actually gets killer results anyway)

The point is, when I try to whip out an arrangement and get an idea down, I tend to reach for the quickest solution that requires the least amount of linking/routing and tinkering. Autoduck is killer, but its sync only, there's no way to give it a sidechain input (unless I'm missing something)

Thanks!
