You are one of those who can hear this
Nothing you can do to remove this unpleasant sound it's part of the software!!
I was one of those reporting it in the beta testing team but I can understand that they will not change everything just for me so the more people who complaint the better chance we have to get a correction.
It's been a while since I post here & I still can't understand that Keyrite Pro is selling at that price knowing it can't do the job it suppose too!!
With all respect to MTU because I love their products and also their support, I honestly believe that their Key changer shouldn't be offered has is
