Weird problem on Logic Pro X controlling Helix LT in Helix Posted January 6, 2018 Hi guys, I've got a question for you. Since this is my first post on this forum I'd like to introduce myself: I am Fed, a guitarist, mixing and mastering engineer from the North of England. I am setting up a live rig with my band: a MacBook running Logic Pro X that controls our lighting system, backing tracks, my Fractal Ax8 and my guitarist's Helix LT. I've read the entire manual, done a bit of trial and error and I've managed to setup all the CC/PC and everything works properly until I move the playhead in Logic (both with the mouse or the hotkeys). Each time I move the playhead the Helix goes on tuning mode, the next time it turns off the tuning mode (and go on and on) without any apparent reason. If I save the Logic project, close the project, open it again and I start it from the top without stopping or moving the playhead at all it works fine, but the first time that I move the playhead it start to act crazy again. Are there some settings I need to change? Has someone got this problem and know how to solve it? What am I doing wrong? I can do a video if it helps you to understand, thank you in advance!
