Logic Pro X Audio/Midi Synch Error??


New Member
New to Logic and LUG, here. Having this issue: On only my 2nd project, after recording three guitar tracks through Logic Instruments and fiddling with Drummer, I got sandpaper audio and this message: "Error while trying to synchronize audio and midi. Sample rate 61,650 recognized. Check conflict between Logic Pro X and external device." Upon several replays, including after full shutdowns, the same message would appear, yet with seemingly random sample rates of 56,126, 60,373, 60,993, etc. being named. I had changed nothing of the sort throughout tracking those few tracks.
Old wounds from Cubase/Windows XP are reopening...any suggestions? My setup is described in my signature below. Thanks!
