I updated to the latest version available with no problems a few weeks ago, but for less than a week, I have to state that the expression pedal is going crazy, as soon as I step on it. When I engage a preset and don't use the expression pedal to control a knob, it's OK, but as soon as I step on it, values of the controlled knobs are going up and down pretty quickly, even if I stop to step on the expression pedal. I reinitialized my TF and that made no changes to this strange behaviour.
I use a Boss EV5 with which I didn't have any problem yet… Any ideas? I remember that someone had the same problem a while ago on this board, but I'm not able to find these related posts.
