Has anyone noticed if you push multiple streamdeck buttons, for instance if you have several push to talk audio bus buttons for your mic, and then push another button that sometimes other functions trigger that you did not want to?

And part 2, why does the ActiveInput function not signal to vMix that a transition has occurred? This makes it impossible to use a stream deck as a preview/program similar to a real broadcast switcher. Any triggers programmed into inputs do not fire if you make that input the "Active" input. I guess one could just write scripts but what a pain. (or am I missing a function that does what I want, put a input to program (output1) and do whatever triggers have been added to said input)

Also it would be nice if vMix could send return info to the StreamDeck so you could actually do change-states for toggle buttons. Also multiple actions would be nice as well.

Sound to me like you have one shortcut doing 2 things. Double check your assignment.

As dmwkr said, using activators (https://www.youtube.com/watch?v=oPG6eq0ZiGg), you can turn the Stream Deck into a full fledged mixer, with preview color and program color that change automatically based on preview/program, audio on/off, etc.

You can set a shortcut to do multiple actions as well.

Awesome, let us know if you run into more issues.
