Hey, I'm using a X-52 Pro and would like to have a push to talk button on it. I already have a good profile but I don't know what the command is to set up a button as a push to talk key in Teamspeak and Ventrilo. Can anybody help me out with that?

Well, I have my push-to-talk button set up in teamspeak/ventrilo, for me that is [middle mouse button]. Then bind your key in the X-52 profile editor. (For me that is the middle mouse button).

HiTop-
I bind the capslock key to my TQS for Ventrilo - then just go into Ventrilo setup and set that as your push-to-talk hotkey.
