Hi,

Don't know if this has been mentioned here before, but Companion is an app to give the Elgato Stream Deck the ability to control all kinds of A/V equipment.
The latest development builds support vMix among lots of other apps and hardware gear.

I don't have a StreamDeck, but I have run the setup gui, and it seems to have quite a complete set of functions, you can set up many functions per key, and you can even trigger a different function on key down and up.

Has anyone with a streamdeck tried this yet?
