Yes, fortunately I do not really do any recording and it was not a critical situation. My biggest relief is that I am pretty sure that my QC unit itself is not faulty. I do worry a bit about how much of a hassle it would be if the unit fails… and the procedure for getting it fixed. But it’s not broke, so we don’t need to fix it! I will be keeping an eye out for what could possibly be causing the issue. You hit the nail on the head when you said “so many variables.” It is truly mind boggling. God bless!
