I having an issue with Helix and Logic losing "sync" after a few minutes. When I start up Logic everything is fine with about 6.9ms of latency. After a few minutes of playing or just downtime, the latency becomes 3-4 full seconds. I reset the core audio in Logic and it is back to normal but only for a few minutes then it's back to the huge delay. I just updated to OS X 10.13.1 and Helix 2.30 but the problem was there before and after the updates. Has anyone experienced anything similar?
