Using triggers as Sidechain noisegate?

Simply route the trigger out to the side-chain input of your noise gate (via an auxiliary send perhaps), which is placed on the corresponding tom track. Set the gate to be triggered via the side-chain input, and set the threshold and various other settings accordingly.

This varies from plug to plug, and DAW to DAW, but the basic principle remains the same.
 
Nudge the trigger tracks like 5ms earlier than the mic tracks. This will let your gate open just before so you get the full transient of the attack.
 
i do this on snare.
use my snare trigs sidechained to the s/c input on channelstrip. sooooooo handy
 
^ That's what I was thinking, but nobody has a fucking gate for live use EVER.

I have one in my liverack.

(LIVE SOUND) So, lets say I have a DBX 166XL, which has sidechain on both channels. I run my signal, as normal, through for the drums...lets say kick/snare for this purpose. It has a sidechain TRS insert on it. Would I only need to worry about the input, unless I had a drum brain in the loop next?

I'd be interested in trying this out for live if benefits are to be had. I only ever heard of this being used for recording
