Yes, just enable the 'Inverse' option when you define the PTT and it will change to push-to-mute.
Thanks!!! Unfortunately my controllers are sending a lot of inputs from the resting state of various switches (as well as some spurious inputs that I don't quite understand) so I cannot assign my PTT correctly :( Not FOXVox's fault... Guess I will have to go with a voice command like you have programmed in your BMS library.
Any way to manually set a PTT button without using CAPTURE?
Sorry to use this means of communication. I didn't see any other contact methods for you.
